Picture this. You spend three weekends and most of a marketing budget building a campaign for your new cold-brew concentrate. The hero line writes itself: "Acme Cold Brew — Doctors Recommend It for Energy and Focus." It tests beautifully. It converts. And then, eight months later, a polite but unsmiling letter arrives from a state Attorney General's office asking you to produce the clinical studies behind that "doctors recommend it" claim — the studies you, in fact, do not have, because no doctor ever recommended anything and you thought "doctors recommend" was just the kind of thing everybody says.

That, in miniature, is advertising law. It is not really about lawyers, or even about lying. It is about the gap between what your ad says — including what it cleverly implies — and what you can actually prove. Close that gap and you can be as bold, funny, and persuasive as your imagination allows. Leave it open and you have handed a regulator, a competitor, or a plaintiff's lawyer a free claim.

This guide is written for the small-business owner, the founder, the marketing lead, and the general-practice attorney who suddenly has an advertising question on their desk. We have kept it in question-and-answer form because that is how these issues actually arrive — one nervous "wait, can we say that?" at a time. A judge or seasoned regulatory lawyer will find the citations they expect; a first-time entrepreneur will find every term of art explained in plain language the first time it shows up. Both can read it start to finish or skip to the section that is keeping them up at night.

A quick map of where we are going. We start with the constitution of advertising law — the Federal Trade Commission Act and its three commandments. Then we dig into substantiation (the single most important and most ignored rule), the difference between express, implied, monadic, and comparative claims, deception versus unfairness, endorsements and influencers under the heavily updated 2023 rules, native advertising, "Made in USA," green claims, pricing and "free" offers, bait-and-switch, and comparative advertising. After that we turn to how you reach customers — email, texts, telemarketing, subscriptions, and marketing to children — where a different set of statutes governs. We close with competitor disputes, the fifty-state overlay, penalties, a practical compliance checklist, and a focused FAQ. If you market a product or service in the United States, something in here applies to you today.

The Foundation: The FTC Act and Its Three Commandments

What is the basic law of advertising in the United States?

The single most important source of advertising regulation in the country is the Federal Trade Commission Act — the FTC Act for short — codified at 15 U.S.C. §§ 41–58. Its operative engine is Section 5, which prohibits "unfair or deceptive acts or practices in or affecting commerce" (15 U.S.C. § 45(a)). That phrase is doing an enormous amount of work. It is the legal hook for nearly every advertising enforcement action you have ever read about, and it applies to advertising in every medium: television, radio, print, billboards, packaging, email, websites, search ads, social posts, podcast reads, and the influencer video your niece's favorite creator just posted.

Crucially, the FTC does not enforce Section 5 by issuing a code of ten thousand specific rules. It mostly works by accretion — through investigations and lawsuits against individual advertisers, consent orders, advisory opinions, informal business guides, formal policy statements, and a handful of substantive rules. Over the decades that body of guidance has hardened into a remarkably consistent set of principles, and because state regulators, the courts, and the advertising industry's own self-regulatory bodies all tend to follow the FTC's lead, its influence reaches far beyond the matters it personally prosecutes.

From Section 5, practitioners and the FTC distill three rules that are easy to memorize and surprisingly hard to live by:

  1. Advertising must be truthful and non-deceptive. An ad cannot say or imply something that is likely to mislead a reasonable consumer about something that matters.
  2. Advertisers must have a reasonable basis for their claims before the ad runs. This is the substantiation requirement, and it is the rule small businesses violate most often without realizing it.
  3. Advertising — and business practices generally — cannot be unfair. Even a literally accurate ad can cross the line if it causes substantial, unavoidable consumer harm that is not outweighed by benefits.

The Federal Trade Commission — an independent federal agency — is the primary cop on this beat, but it is not the only one. The Food and Drug Administration (FDA) handles the labeling of food, drugs, supplements, medical devices, and cosmetics under the Food, Drug, and Cosmetic Act (21 U.S.C. §§ 301–399); the FTC handles the advertising of most of those products under a long-standing liaison agreement, though the line between "label" and "advertising" blurs online. The U.S. Department of Agriculture regulates the labeling of meat and poultry. Other agencies have carved-out jurisdiction: the Department of Transportation over airlines, banking regulators over banks, the SEC over securities, and so on. And — critically for any small business — every single state has its own consumer-protection statute that reaches advertising aimed at its residents. We will return to that fifty-state overlay near the end, because it is where a lot of real-world risk lives.

Who actually enforces all of this?

More people than you might think, which is why "nobody will notice" is a poor compliance strategy. The FTC enforces Section 5 nationally, focusing on widespread deception and on claims touching health, safety, and consumers' wallets. State Attorneys General enforce their own "UDAP" statutes (short for Unfair and Deceptive Acts and Practices laws) and frequently coordinate in multistate sweeps. Competitors can sue you under Section 43(a) of the Lanham Act (more on that below). Private consumers can sue under most state UDAP statutes, often as class actions and often with the prospect of attorney's fees and statutory or even treble damages. And the advertising industry polices itself through the National Advertising Division (NAD) of BBB National Programs, a private self-regulatory body whose decisions, while not legally binding, carry real weight and can be referred to the FTC if an advertiser refuses to comply.

For a sense of how seriously courts take these standards, and how an ordinary commercial dispute can become a federal case, our discussion in false advertising and Lanham Act Section 43(a) walks through competitor litigation in detail.

What makes an advertisement "deceptive"?

The FTC's framework comes from its 1983 Deception Policy Statement. An ad is deceptive if it contains a representation or omission that (1) is likely to mislead consumers (2) acting reasonably under the circumstances about (3) a material fact — one likely to affect their decision to buy or use the product.

Three points repay careful attention.

First, likely to mislead is the standard, not actually misled. The FTC does not have to parade injured consumers through a hearing room. It is enough that the ad has a tendency to deceive a reasonable person.

Second, the reasonable consumer is the audience, and the FTC puts a surprisingly concrete number on this. It reads the ad the way an ordinary member of its target audience would — looking at the whole package of words, phrases, images, sounds, and context, not isolated sentences — and as a rule of thumb it treats any interpretation communicated to roughly 15% or more of consumers as a reasonable interpretation that must be true and substantiated. The agency has found reasonable interpretations at rates as low as 10–12%, so claims that survey in the 10–14% band deserve caution; below about 10%, the FTC generally treats the reading as noise. The practical lesson is that you are not safe just because most people read your ad correctly — you can be liable for a misleading impression that only a sizeable minority takes away. And the standard adjusts to the audience: if your ad targets sophisticated engineers, the reasonable engineer is your yardstick; if it targets people in financial distress or, especially, children, the standard tightens.

Third — and this is the trap — the FTC reads both express and implied claims, and it polices them identically. The level of proof you need does not depend on whether the claim was stated outright or merely suggested. An express claim is stated in so many words: "ABC Mouthwash prevents colds." An implied claim is one a reasonable consumer takes away even though the ad never says it: "ABC Mouthwash kills the germs that cause colds" implies that it prevents colds. You are responsible for substantiating both, including reasonable implied claims you never meant to make. The classic illustration is Kraft, Inc. v. FTC, 970 F.2d 311 (7th Cir. 1992), where every individual statement in a cheese-slice ad was literally true and substantiated, yet the ad as a whole implied that each slice contained the calcium of five ounces of milk — a claim Kraft had not intended, could not substantiate, and was held liable for anyway. The lesson: read your own ad as a skeptical stranger would, then ask whether you can prove the impressions it leaves.

What is the "net impression," and why do regulators care about the whole ad?

The doctrine that does Kraft's heavy lifting is the net impression principle, and it deserves its own moment because it is where unintended claims hide. The FTC does not grade your ad sentence by sentence; it asks what the entire package — headline, body copy, fine print, images, music, video, and context — communicates to a reasonable consumer taken together. An ad can be a string of individually true, individually substantiated statements that, in combination, imply a further claim that is false. A box of cereal photographed resting on shafts of wheat may imply "whole grain" even if the words never appear. A weight-loss ad that pairs a "clinically studied ingredient" statement with before-and-after photos may imply that the product, not just the ingredient, was clinically proven to cause the pictured results.

Two corollaries follow. If an ad can reasonably be read in more than one way, every reasonable reading must be true — you do not get to pick the charitable interpretation. And a disclaimer or disclosure can clarify or limit a claim, but it cannot contradict the main message; fine print that says the opposite of the headline does not save the ad. This is why experienced advertising counsel read a draft twice: once for what it says, and once for what it leaves a distracted, skeptical reader believing.

What makes an advertisement "unfair," as opposed to deceptive?

Unfairness is the FTC's second, less-used weapon, now codified at 15 U.S.C. § 45(n). A practice is unfair if it (1) causes or is likely to cause substantial injury to consumers, (2) that consumers cannot reasonably avoid themselves, and (3) that is not outweighed by countervailing benefits to consumers or competition. Note that an ad can be perfectly truthful and still be unfair — for example, a high-pressure sales practice that exploits a vulnerable population, a billing practice that traps customers, or a data practice that exposes consumers to harm they had no way to foresee. Unfairness shows up frequently in privacy and data-security enforcement, but it lurks behind aggressive sales, subscription, and billing tactics too — and, as we will see below, it is the FTC's primary tool against manipulative "dark pattern" interfaces.

Substantiation: The Rule You Cannot Skip

What evidence do I need before I make a claim?

Before an ad runs, you must have a "reasonable basis" for every objective claim it makes. This is the substantiation requirement, and it flows from the FTC's Policy Statement Regarding Advertising Substantiation. "Reasonable basis" means competent, objective evidence in your hands at the time the ad runs — not evidence you intend to gather, and not the fact that the claim happens to be true. You can be liable for an unsubstantiated claim even if it later turns out to be accurate, because the violation is making the claim without support.

How much support is enough? It depends on the claim. The FTC weighs roughly six factors: the type of product, the type of claim, the consequences of a false claim, the benefits of a truthful claim, the cost of developing substantiation, and — importantly — the amount of substantiation experts in the field would consider reasonable. For most ordinary performance claims, reliable evidence appropriate to the claim suffices, and the type of evidence should fit the type of claim: a technical performance claim ("battery lasts eight hours") calls for technical testing or an industry standard, while a sensory claim ("best tasting") calls for properly designed consumer testing or surveys. For health and safety claims, the bar is high: you generally need "competent and reliable scientific evidence," meaning tests, analyses, research, or studies conducted and evaluated objectively by qualified people using methods experts accept. A claim that your supplement "reduces the risk of heart disease" is in the same evidentiary universe as a pharmaceutical claim, even if your product is sold in a health-food store.

There is a special rule for establishment claims — claims that say you have a particular level of proof. "Clinically proven," "tests show," "studies confirm," "two out of three doctors recommend." If you advertise the type of evidence, you must actually possess that type of evidence, at the level claimed, before you publish; the touted benefit must be both statistically and clinically meaningful. "Two out of three doctors recommend ABC Pain Reliever" requires a reliable, methodologically sound survey to that effect; you cannot back it into existence after the fact, and you cannot substitute a different kind of proof for the kind you named.

What is the difference between a "monadic" and a "comparative" claim, and why does it matter?

Beyond the express/implied divide, advertising professionals sort claims a second way that determines how much testing you need. A monadic claim talks about your own product in isolation — "our battery lasts eight hours," "made from fresh-squeezed oranges." A self-comparative monadic claim touts an improvement over your own prior version — "now lasts 25% longer," "new, improved recipe." Even self-comparisons must be measurable and supported, and you cannot stretch general substantiation to cover a narrower claim: data backing "improved recipe" will not, by itself, support "improved chocolatey taste," which needs its own consumer-perception test.

A comparative claim measures your product against a competitor, a subset of competitors, or the market generally, and the substantiation bar climbs accordingly. The rough taxonomy:

  • A qualified superiority claim ("more effective than the leading bug repellent") names or identifies the rival and generally requires head-to-head testing whose results are statistically significant at the 95% confidence level.
  • A qualified parity claim ("works as well as the leading brand") asserts equivalence, which is harder to prove because you must show no perceptible difference; it usually demands larger samples, though a numerical win across the comparison set may suffice without hitting the 95% threshold.
  • An unqualified comparative claim or "dangling comparison" ("longest-lasting sunscreen," "no sunscreen lasts longer") names no one but sweeps the whole field. To support it you must test against a market basket — typically the brands making up the top ~85% of the relevant category by sales, plus any significant player that threshold would omit — using independent market data to define the set.

The takeaway for a small business is blunt: the bolder and more comparative the claim, the more rigorous (and expensive) the testing it requires. "Customers love it" is cheap to support; "outperforms every competitor" is not.

Worked example: the cold-brew problem

Return to Acme Cold Brew and "Doctors Recommend It for Energy and Focus." That is an establishment claim (it asserts a doctor recommendation) and a health-adjacent performance claim. To run it, Acme would need, at minimum, a methodologically sound survey of physicians showing the recommendation, plus competent and reliable scientific evidence for the energy-and-focus benefit. Acme had neither. The honest, runnable version might be: "Acme Cold Brew — Bold, Smooth, and Packed With Caffeine to Help You Power Through Your Morning." That is a non-establishment, monadic performance statement tied to a real, measurable ingredient (caffeine), and it stays clear of the regulated territory of disease and health claims. If Acme wanted to go further and say "More caffeine per ounce than the leading cold brew," it would have crossed into a qualified superiority claim and would need head-to-head lab testing against the named or identified leader, significant at the 95% level. The lesson is not "say less" — it is "say what you can prove, and prove what you say."

Are glowing customer reviews enough to back up a claim?

Generally, no. Testimonials from satisfied customers do not substitute for objective substantiation, especially for health, safety, or any claim requiring objective evaluation. A wall of five-star reviews saying "this cured my migraines" does not let you advertise that your product cures migraines. (Reviews carry their own rules, too — see the endorsement section below, and note the FTC's 2024 rule on fake and manipulated reviews discussed there.)

We offer a money-back guarantee. Doesn't that cover us?

No. A money-back guarantee is a nice feature, but it is not a get-out-of-substantiation-free card. The FTC has long held that the fact that few people demanded refunds does not prove the claim was true, and offering a guarantee does not relieve you of the duty to have a reasonable basis before you advertise. Substantiate first; guarantee second. (A guarantee also has to be honored on its own terms, and the way you advertise it must itself be truthful — "lifetime guarantee" had better mean what a reasonable consumer thinks it means.)

What is "puffery," and why does it escape these rules?

Puffery is subjective, exaggerated, or vague boasting that no reasonable consumer would take as a factual claim. "World's best cup of coffee," "unbeatable style," "the most fun you'll have all summer." Because puffery makes no measurable, falsifiable assertion, it generally does not require substantiation and is not actionable as false advertising. The danger is the gray zone: "clinically proven best," "scientifically superior," or any boast that smuggles in a measurable, comparative, or quasi-scientific element stops being puffery and becomes a claim you must prove. The test courts and the NAD apply is whether the statement makes a specific, measurable representation a consumer would rely on, or merely strikes a mood. When in doubt, assume it is a claim.

Endorsements, Testimonials, and Influencers

Are there special rules for endorsements and testimonials?

Yes, and they were significantly tightened in 2023. The governing framework is the FTC's Guides Concerning the Use of Endorsements and Testimonials in Advertising, found at 16 C.F.R. Part 255. The FTC published a comprehensive update to these Guides effective in 2023 — the first major overhaul in over a decade — explicitly to address the influencer era, social media, and fake reviews.

The bedrock principles:

  • An endorsement must reflect the honest opinions or experience of the endorser.
  • An endorsement may not make any claim that would be deceptive, or that could not be substantiated, if the advertiser made it directly. You cannot launder an unsubstantiated claim through someone else's mouth.
  • An advertiser must disclose any material connection between itself and an endorser that consumers would not expect and that might affect the weight or credibility they give the endorsement.

That last point — material connection disclosure — is where most small businesses get into trouble, usually innocently.

What counts as a "material connection," and how do I disclose it?

A material connection is any relationship between you and the endorser that might affect how much credibility a consumer gives the endorsement and that the consumer would not reasonably expect — anything that "puts the speaker's independence in question." The obvious one is payment. But it sweeps far wider: free products, discounts, gift cards, sweepstakes entries, affiliate commissions, a future business relationship, an employment relationship, or a family tie. If your employee posts a five-star review of your product without disclosing they work for you, that is an undisclosed material connection. If you ship free product to micro-influencers in exchange for posts, those posts need disclosures even if you never said the word "review."

Disclosure must be clear and conspicuous: hard to miss, in the same place as the endorsement, and in plain language. The FTC's guidance (including its .com Disclosures: How to Make Effective Disclosures in Digital Advertising) and the 2023 Guides converge on a few concrete rules:

  • Use simple, unambiguous language. "#ad," "Sponsored," "Paid partnership," or "Thanks to Acme for the free sample" works; vague tags like "#sp," "#collab," "#ambassador," or burying "#ad" in a thicket of thirty hashtags does not.
  • Put the disclosure in the post itself and proximate to the endorsement — not solely in a platform's built-in tool that a viewer might not see, not buried in a link or the influencer's bio, and not only "above the fold" where it scrolls away. If scrolling is unavoidable, cue the viewer to scroll. Make sure nothing else on the screen distracts from it.
  • In a video, a fleeting on-screen line is not enough. The disclosure should be within the video itself — spoken and/or superimposed and held long enough to read and understand — at the point the endorsement is made. The FTC has even drilled down to platform-specific advice (for example, superimposing a disclosure on a Snapchat or Stories image).
  • Make it understandable to ordinary viewers and, where the audience includes them, to children.

The 2023 update also clarified that the advertiser, the endorser, and intermediaries like ad agencies and influencer-marketing firms can all face liability. You cannot simply hand a brief to an influencer and look away. The FTC expects brands to have a real program: a written social-media endorsement policy adopted before engaging influencers, training for employees, agencies, and influencers on that policy, ongoing monitoring of what gets posted, and prompt corrective action — fixing or removing noncompliant posts and, if necessary, ending the relationship — when an endorser slips. The Guides also took aim at fake reviews, suppressing or "gating" negative reviews, and "review hijacking." For a model, see our broader treatment of social media law basics and the brand-side perspective in brand protection online.

What about consumer testimonials and "results not typical"?

Consumer testimonials must reflect the typical experience users can generally expect — not a cherry-picked best case. The old escape hatch ("results not typical" or "your results may vary") does not cure an atypical testimonial. If you feature someone who lost 50 pounds, the ad communicates that buyers can expect roughly that result; if the typical user loses five pounds, you have a deception problem that a disclaimer will not fix. Either feature typical results or clearly convey what the generally expected results are.

Do celebrity and expert endorsements have extra requirements?

Yes. A celebrity endorsement must reflect the celebrity's genuine, current views, and if the ad implies the celebrity uses the product, the celebrity must actually use it. The advertiser has an ongoing duty to ensure the endorsement still reflects the endorser's honest opinion — so a years-old endorsement deal can become a liability if the celebrity has moved on or switched brands. An expert endorsement requires that the person genuinely be qualified as an expert and that the endorsement be supported by an actual examination or testing of the kind other experts in the field would conduct. A celebrity in a lab coat who never tested the product is a recipe for an enforcement action.

The 2024 federal Rule on the Use of Consumer Reviews and Testimonials (16 C.F.R. Part 465) went further still, expressly prohibiting buying or selling fake reviews and testimonials, certain insider reviews without disclosure, the suppression of honest reviews (including through unfounded legal threats), and fake indicators of social-media influence such as bought followers — and, importantly, it carries civil penalty authority, which the older endorsement Guides do not. Because the law in this area is genuinely evolving, treat any review-gating, incentivized-review, or influencer program as something to design carefully and document.

What is "native advertising," and how do I keep it legal?

Native advertising is paid content designed to match the look and feel of the surrounding non-advertising content — the "sponsored article" that reads like editorial, the in-feed promoted post that looks like a friend's post, the "recommended for you" piece that is actually an ad. The FTC's guidance (the Enforcement Policy Statement on Deceptively Formatted Advertisements and the companion "Native Advertising: A Guide for Businesses") boils down to one principle: consumers are entitled to know when they are looking at an ad. If the format would lead a reasonable person to believe the content is independent, editorial, or user-generated when it is in fact paid, you must disclose its commercial nature clearly and up front, before the consumer engages with it. Labels like "Ad," "Advertisement," "Paid Content," or "Sponsored by Acme" work; coy labels ("Promoted," "Presented by," "Featured partner") may not be clear enough depending on context. The deception lies not in the content but in the disguise.

Specific Claims That Draw Scrutiny

When can I say my product is "Made in USA"?

This is one of the most enforced — and most misunderstood — claims in American advertising. To make an unqualified "Made in USA" claim, your product must be "all or virtually all" made in the United States. That means all significant parts and processing are of U.S. origin, and the product contains no — or only a negligible amount of — foreign content. Final assembly here is not enough if the guts are imported. The phrase reaches more than the literal words "Made in USA": under the rule, any unqualified U.S.-origin representation — "manufactured," "built," "produced," "created," "crafted" in the United States or in America — is covered, and so are implied origin claims conveyed by U.S. flags, maps, or "American-made" imagery in context (though a U.S. brand name or trademark, standing alone, usually is not treated as an origin claim).

This is no longer just a policy matter. In 2021 the FTC issued the Made in USA Labeling Rule, codified at 16 C.F.R. Part 323, which makes the "all or virtually all" standard a formal rule and — significantly — authorizes civil penalties for violations. The per-violation maximum is adjusted annually for inflation and currently runs in the tens of thousands of dollars per violation (it has stood at roughly $43,792 per violation in recent years), and the FTC has used it aggressively, extracting six- and seven-figure penalties for false "Made in USA" labeling. The rule reaches labels and mail-order/online promotional materials bearing a "Made in USA" seal or stamp; for U.S.-origin claims in other advertising and for qualified claims, the FTC falls back on its general Section 5 authority and its longstanding Enforcement Policy Statement on U.S. Origin Claims.

How does the FTC decide whether a product is "all or virtually all" domestic? There is no bright-line percentage. The agency weighs the proportion of U.S. manufacturing costs (using cost of goods sold for finished inventory) and the remoteness of any foreign content in the manufacturing chain. A table lamp assembled in the United States from a U.S.-made shade and brass but an imported base that makes up a meaningful share of cost would not qualify, because the imported base is both significant and proximate to the finished product. Manufacturers are expected to "look back" far enough up the supply chain to capture significant foreign inputs.

If your product does not clear the bar, you are not stuck with silence — you can make a truthful qualified claim that names the foreign content or limits the claim to what is genuinely domestic: "Made in USA of U.S. and imported parts," "Assembled in USA from imported components," "80% U.S. content," or "Designed in California, made in Vietnam." Two cautions. First, an "Assembled in USA" claim is itself deceptive if the assembly is a trivial last step that does not "substantially transform" imported components. Second, Customs and Border Protection runs a separate country-of-origin marking regime under the Tariff Act of 1930, keyed to where a product was "substantially transformed" (a name/character/use change). A product last substantially transformed abroad must carry a foreign country-of-origin mark — and complying with CBP does not mean you comply with the FTC, so both regimes have to be satisfied at once. Be precise, because vagueness here is expensive.

Are there special rules for environmental or "green" claims?

Yes — the FTC's Guides for the Use of Environmental Marketing Claims, universally called the Green Guides and found at 16 C.F.R. Part 260 (originally 1992, revised 1998, last comprehensively updated in 2012). The Green Guides are not themselves law, but they explain how the FTC applies Section 5 to environmental claims, and they apply to all express and implied green messages, whether conveyed by words, symbols, logos, or brand names. A few load-bearing principles:

  • No broad, unqualified benefit claims. "Eco-friendly," "green," "sustainable," and "environmentally safe," standing alone, are nearly impossible to substantiate because they imply a vast, unqualified environmental benefit. You may make a general benefit claim only if you can substantiate all the express and implied benefits it conveys; otherwise, tie the claim to a specific, substantiated attribute — "made with 30% post-consumer recycled content," not "eco-friendly."
  • Do not overstate, and make clear what the claim covers. Labeling packaging "recycled" can mislead a consumer into thinking the product inside is recycled too; say which. And "50% more recycled material than before" is deceptive if it actually means a jump from 2% to 3% content — technically true, but it implies a far larger change. Qualifications must be clear, prominent, and in adequate type, not an asterisk in six-point font.
  • "Recyclable" requires that recycling facilities be available to a substantial majority of consumers or communities where the item is sold; otherwise, qualify it.
  • "Degradable / biodegradable" generally requires that the product completely break down within a reasonably short time — the FTC uses roughly one year under customary disposal conditions — and unqualified degradable claims are improper for items typically sent to landfills, incinerators, or recycling facilities, where decomposition takes far longer.
  • "Recycled content," "compostable," "non-toxic," "ozone-friendly," "renewable energy," and carbon-offset claims each carry their own substantiation expectations.

The Green Guides have been under review and may be updated to address modern issues such as carbon offsets, "renewable," and the word "sustainable"; treat this area as evolving and substantiate conservatively. State law adds another layer — California, in particular, regulates terms like "recyclable" and "compostable" by statute (see, e.g., Cal. Pub. Res. Code § 42357.5), so a claim that is fine federally may run afoul of a state rule.

What are the rules on pricing claims and "sale" prices?

The same truthfulness and substantiation standards govern price claims, interpreted through the FTC's Guides Against Deceptive Pricing (16 C.F.R. Part 233). The central concept is the reference price — the "regular" or "was" price you compare your sale price against. To advertise "Was $100, Now $50," the $100 must be a genuine, bona fide price at which you actually offered the item, in good faith and in the ordinary course of business, for a reasonably substantial period (16 C.F.R. § 233.1) — not a fictitious, inflated "regular" price that exists only to make the "sale" look dramatic. Perpetual "sales," phantom markdowns, and fake "compare at" prices are deceptive. The same applies to "going out of business" sales (the store must actually be going out of business) and "lowest price" or "we won't be undersold" claims (which require real, ongoing substantiation).

Pricing is also where state law bites hard. Many states have detailed deceptive-pricing and former-price advertising statutes that prescribe exactly how long and how recently an item must have sold at the "regular" price, and class actions over phantom "compare at" pricing — particularly at outlet stores — have been a cottage industry. If you run comparison pricing, build a documented record of your actual regular prices and how long they were in effect.

When can I advertise something as "free"?

"Free" is a magic word, and the FTC's Guides Concerning Use of the Word "Free" (16 C.F.R. Part 251) keep it honest. The core rule: when a "free" offer is conditioned on buying something else ("buy one, get one free"), you must not raise the price of the item the customer has to buy, or reduce its quantity or quality, to recover the cost of the "free" item. The thing that is free must be genuinely free given the regular price of the required purchase. You must also clearly and conspicuously disclose the terms of the offer — what the customer must buy, any time limits, shipping or handling charges, and so on — close to the "free" claim, not buried in fine print. The same logic governs "free trials" that roll into paid subscriptions (which also implicate the negative-option rules discussed below) and "free gift with purchase" promotions.

What is "bait and switch," and why is it illegal?

Bait-and-switch advertising is an offer to sell a product the advertiser does not actually intend to sell, used as "bait" to lure customers in and then "switch" them to a different, usually pricier item. It is addressed in the FTC's Guides Against Bait Advertising (16 C.F.R. Part 238). The illegality is the intent: advertising the irresistible loss-leader you never planned to honor, then disparaging it, refusing to take orders, demonstrating a defective version, or claiming it is sold out the moment a customer walks in. Genuinely running out of an honestly advertised item is not bait-and-switch — which is why limited-quantity disclosures ("while supplies last," "5 available at this price per store") and, in the grocery context, rainchecks under the FTC's Retail Food Store Advertising Rule (16 C.F.R. Part 424) matter. Advertise what you intend to sell, in quantities you can reasonably meet, and you are clear.

Is comparative advertising — naming a competitor — legal?

Yes. Comparing your product to a named competitor's is not only legal, the FTC has long encouraged it, on the theory that truthful comparisons help consumers make rational decisions and sharpen competition — and the agency has taken the position that industry self-regulatory codes should not be used to discourage truthful brand-to-brand comparisons. The FTC's Statement of Policy Regarding Comparative Advertising applies the same standard it applies to all advertising: comparisons must be truthful, not deceptive, and substantiated. The FTC does not impose a higher legal burden just because you named a rival — but, as the substantiation section above explained, a comparative claim inherently requires more rigorous proof (head-to-head testing, 95% confidence, the right comparison set).

But comparative advertising carries a second, sharper risk that ordinary advertising does not: the named competitor can sue you. That brings us to the Lanham Act.

What is the Lanham Act, and how can a competitor sue me over my ads?

Section 43(a) of the Lanham Act, 15 U.S.C. § 1125(a), gives a private right of action — competitor versus competitor — for false or misleading advertising. While the FTC protects consumers, the Lanham Act lets your competitors protect themselves from your false claims (and lets you protect yourself from theirs).

To prevail, a Lanham Act false-advertising plaintiff generally must show: (1) a false or misleading statement of fact in commercial advertising; (2) that the statement actually deceived or is likely to deceive a substantial segment of the audience; (3) that the deception is material (likely to influence purchasing decisions); (4) that the goods or services entered interstate commerce; and (5) injury or likely injury to the plaintiff. The proof required turns on a crucial distinction. If a statement is literally false — including by "necessary implication," where the ad can only be read one way — a court may enjoin it without any survey evidence of how consumers understood it. If the statement is literally true or ambiguous but misleading, the plaintiff ordinarily must prove, usually through a consumer survey, that consumers actually took away the deceptive message. That single fork explains why so much Lanham Act litigation is a battle of survey experts.

A few landmark refinements every advertiser should know:

  • Standing. In Lexmark International, Inc. v. Static Control Components, Inc., 572 U.S. 118 (2014), the Supreme Court replaced a tangle of circuit tests with a single standard: to sue, a plaintiff must fall within the "zone of interests" the Lanham Act protects (commercial, not consumer, interests) and must show injury proximately caused by the defendant's misrepresentations.
  • Food and drug overlap. In POM Wonderful LLC v. Coca-Cola Co., 573 U.S. 102 (2014), the Court held that FDA regulation of a food or beverage label does not preclude a competitor's Lanham Act false-advertising suit. Compliance with one federal regime is not automatic immunity from another.
  • Injunctions. The Trademark Modernization Act of 2020 created a rebuttable presumption of irreparable harm once a plaintiff establishes liability (or a likelihood of success), making injunctive relief easier to obtain in false-advertising cases — and interim injunctive relief is one of litigation's chief advantages over the self-regulatory route, because it can actually stop a damaging ad while the dispute proceeds.

If you publish a comparative claim — "Acme Cleaner removes 40% more grime than Brand X" — assume Brand X's lawyers will read it, demand your head-to-head test data, and sue if it is thin. Have the testing (statistically significant, properly designed, run against the current version of the named product) in hand before you hit publish. And before you fire the first shot at a rival, audit your own claims — the surest way to invite a counterclaim is to challenge a competitor while your own comparative ad rests on an outdated formulation. Our deep dive at false advertising and Lanham Act Section 43(a) maps the litigation in detail, and our guide to writing a demand letter covers the cheaper opening move.

Is there a faster, cheaper alternative to suing a competitor?

Often, yes — and usually several, which is why litigation should be a genuine threat held in reserve rather than the first move. Short of court, a challenger can call the competitor's counsel, send a demand letter, or submit a network/media challenge asking the broadcaster or publisher running the ad to pull it under its own advertising standards (fast and confidential, though each network runs its own process and a win on one does not bind the others). The marquee self-regulatory option is the National Advertising Division (NAD) of BBB National Programs.

NAD is a private forum where one advertiser challenges another's national or regional claims; the advertiser bears the burden of proving every express and reasonably implied claim is truthful, not misleading, and fully substantiated. It is far cheaper and faster than federal litigation, its staff attorneys are genuine experts in weighing substantiation, and although compliance is voluntary, national advertisers almost always participate — and an advertiser that refuses to participate or comply can be referred to the FTC, which acts on those referrals. Since 2020 the NAD has run three tracks: the Standard Track (most cases, typically a few months to decision); the Complex Track for matters needing consumer-perception surveys or technical studies; and Fast-Track SWIFT, which yields a decision in about 20 business days for a single, straightforward issue — limited to challenges over the prominence or sufficiency of disclosures (including influencer, native-ad, and incentivized-review disclosures, via an even quicker "SWIFT–Disclosure" sub-procedure), certain misleading express claims that need no complex evidence, and similar narrow questions. Two caveats: the NAD cannot issue an injunction, so the challenged ad may keep running during the proceeding and any appeal to the National Advertising Review Board (NARB), and because NAD decisions are published, class-action lawyers read them. Courts have nonetheless recognized the NAD's expertise, occasionally pausing litigation to let it finish (see, e.g., Russian Standard Vodka (USA), Inc. v. Allied Domecq Spirits & Wine USA, Inc., 523 F. Supp. 2d 376 (S.D.N.Y. 2007)). For many small businesses, an NAD challenge is the sensible first formal move against a competitor's overreaching claim — and a reason to make sure your own claims would survive one.

How You Reach Customers: Email, Texts, Calls, Subscriptions, and Kids

Everything above concerns what you say. The next cluster of laws governs how you deliver the message and how you bill for it — and these are the rules with the scariest math, because several of them carry per-message or per-call statutory damages that multiply terrifyingly across a marketing list.

What do I need to know about email marketing? (CAN-SPAM)

Commercial email is governed by the CAN-SPAM Act of 2003, 15 U.S.C. §§ 7701–7713, and the FTC's implementing rule (16 C.F.R. Part 316). Despite the nickname, CAN-SPAM does not require permission before you email — but it imposes firm requirements on every commercial message:

  • No false or misleading header information. Your "From," "To," "Reply-To," and routing data must be accurate and identify the sender.
  • No deceptive subject lines. The subject must reflect the content.
  • Identify the message as an ad (the law gives latitude on how, but the commercial nature must be clear).
  • Include a valid physical postal address for your business.
  • Provide a clear opt-out mechanism, honor opt-outs within ten business days, and keep honoring them — you cannot sell or transfer an address that has opted out.

Penalties are steep — civil penalties per violation, with each separate noncompliant email potentially counting, adjusted for inflation — and "you" includes the company whose product is promoted, not just the firm that pressed "send." For a thorough treatment, see the CAN-SPAM Act guide. One caution: CAN-SPAM is a federal floor, and comprehensive state privacy statutes increasingly layer additional requirements; many senders also face the practical demands of mailbox providers and, if they have any international audience, the consent rules of jurisdictions like the EU.

What about text-message and phone marketing? (The TCPA)

Here is where the math gets genuinely frightening. The Telephone Consumer Protection Act (TCPA), 47 U.S.C. § 227, restricts marketing calls and texts. In broad strokes:

  • Marketing texts and prerecorded or autodialed marketing calls to cell phones generally require prior express written consent from the recipient. A text message counts as a "call" under the TCPA.
  • Prior express written consent is a defined term — a clear, conspicuous, signed (including electronically) agreement that the consumer will receive marketing messages, not something buried in a privacy policy.
  • The TCPA also undergirds the National Do Not Call Registry and limits the hours and manner of telemarketing.

The reason lawyers treat the TCPA with such respect is its private right of action with statutory damages of $500 per violation, trebled to $1,500 for willful or knowing violations — per call or text. Send an unconsented marketing blast to 10,000 numbers and you are theoretically staring at $5 million, or $15 million if willful. The TCPA is a magnet for class actions.

The law here is in flux. In Facebook, Inc. v. Duguid, 592 U.S. 395 (2021), the Supreme Court narrowed the definition of an "automatic telephone dialing system" (ATDS), reducing exposure for some technologies — but the consent rules for prerecorded calls and texts, and the Do Not Call rules, remain very much in force, and the FCC has continued to tighten consent and revocation requirements. Several states (Florida, Oklahoma, Washington, and others) have enacted their own "mini-TCPA" statutes with their own damages, so do not assume the federal analysis ends the inquiry. Before you launch any SMS campaign, get real, documented consent and honor opt-outs ("STOP") immediately.

What rules apply if I sell over the phone? (Telemarketing Sales Rule)

If you sell goods or services by telephone — outbound or, in many cases, inbound — the FTC's Telemarketing Sales Rule (TSR), 16 C.F.R. Part 310, layers on specific duties: prompt disclosure of who is calling and that it is a sales call, disclosure of total cost and material terms before payment, a prohibition on misrepresentations, honoring the Do Not Call Registry and company-specific do-not-call requests, calling-time restrictions, and special rules for prize promotions and certain payment methods. Sweepstakes and prize-promotion calls must disclose the odds (or the factors determining them) and that no purchase is necessary. The TSR is also the original home of the FTC's definition of a "negative option feature," carried over into other regimes below. For most small businesses, the practical takeaway is: telemarketing is heavily regulated, and "we'll just have someone start dialing" is not a plan.

What are "negative option" and auto-renewal offers, and why is the FTC so focused on them?

A negative-option offer is any plan where a customer's silence or failure to act is treated as acceptance of a charge. The FTC recognizes several flavors: prenotification plans (the old product-of-the-month club), continuity plans (recurring shipments until you cancel), automatic renewals (your subscription renews and bills unless you opt out), and free-to-pay conversions (a free or nominal trial that flips to a paid charge). These are squarely in regulators' sights because of the friction many companies build into cancellation.

Several overlapping authorities apply, and it helps to see how they fit. The TSR reaches negative options offered by phone. The FTC's longstanding Negative Option Rule (16 C.F.R. Part 425) reaches only prenotification plans, in any medium. The Restore Online Shoppers' Confidence Act (ROSCA) (15 U.S.C. §§ 8401–8405) reaches online negative options of all types and makes them unlawful unless the seller clearly and conspicuously discloses all material terms before taking billing information, obtains the consumer's express informed consent to the recurring charge, and provides simple cancellation; a ROSCA violation is treated as an FTC Act violation enforceable by the FTC and state AGs. And Section 5 itself sits over everything, letting the FTC reach any negative-option scheme in any medium. The agency has also pushed a "click to cancel" approach — cancellation should be at least as easy as sign-up — and in recent guidance has warned that "dark patterns" (interface designs engineered to trick or trap consumers into recurring charges or to obstruct cancellation) are an unfair or deceptive practice. A wave of state automatic-renewal laws, with California's the most demanding, adds detailed disclosure, consent, and easy-cancellation mandates on top. Because this area has seen heavy rulemaking and litigation, confirm the current state of the federal rule and the relevant state ARLs before launching any subscription — and design the cancellation flow to be as painless as the sign-up flow.

Are there special rules for marketing to children? (COPPA and CARU)

Yes, and they are strict. The Children's Online Privacy Protection Act (COPPA), 15 U.S.C. §§ 6501–6506, and the FTC's COPPA Rule (16 C.F.R. Part 312) require operators of websites and online services directed to children under 13 — and general-audience services with actual knowledge they are collecting data from under-13s — to obtain verifiable parental consent before collecting, using, or disclosing a child's personal information (names, addresses, emails, persistent identifiers, geolocation, photos, voice, and more). COPPA also requires a clear privacy policy, data-minimization and retention limits, and reasonable security. The FTC updated the COPPA Rule in early 2025 to address modern data practices, including limits on targeted advertising to children and stronger consent requirements; treat the details as current and evolving. Penalties are substantial — the FTC has imposed multimillion-dollar and even nine-figure COPPA penalties.

Beyond data, advertising aimed at children is evaluated from a child's perspective, on the premise that younger children may not grasp the persuasive intent of advertising or even recognize that they are being advertised to. The self-regulatory Children's Advertising Review Unit (CARU) of BBB National Programs publishes influential guidelines — covering both child-directed advertising and children's online privacy — that the FTC respects and that most national advertisers to children follow; CARU, like the NAD, refers non-complying advertisers to the FTC. If your product, app, game, or content touches kids, build COPPA compliance in from the start, not after launch.

Industry-Specific and Special-Format Rules

Some categories carry their own overlay. A quick tour, because small businesses are often surprised to learn their product is special.

Health, food, supplements, and OTC drugs. The FTC regulates advertising; the FDA regulates labeling under the Food, Drug, and Cosmetic Act, and the line blurs online. Health claims demand competent and reliable scientific evidence, and disease-treatment or disease-prevention claims for foods and supplements are tightly constrained. Weight-loss advertising draws intense scrutiny — the FTC's "gut check" guidance flags certain claims (e.g., "lose weight without diet or exercise") it considers facially false no matter what evidence is offered.

Credit, leasing, and financial products. The Truth in Lending Act (TILA) and Regulation Z require specific "clear and conspicuous" disclosures whenever a credit ad states certain "triggering terms" (like a down-payment amount or a monthly payment). The Consumer Leasing Act and Regulation M do the same for consumer leases ("$0 down" triggers mandatory disclosures). These are technical regimes; get them right.

Alcohol and tobacco. The FTC can reach deceptive or unfair alcohol and tobacco ads, but the Alcohol and Tobacco Tax and Trade Bureau (TTB) governs much alcohol labeling and advertising, and federal law bans broadcast advertising of cigarettes and smokeless tobacco and mandates health warnings.

Warranties and guarantees. The Magnuson-Moss Warranty Act and FTC rules require that written warranty terms be available to consumers before sale and that ads referencing a warranty disclose how to obtain the details and any material limitations.

Mail, internet, or telephone order sales. The FTC's Mail, Internet, or Telephone Order Merchandise Rule (16 C.F.R. Part 435) requires you to have a reasonable basis to expect you can ship within the time stated — or within 30 days if no time is stated — and to notify customers and offer refunds if you cannot.

Sweepstakes and contests. A promotion that requires a purchase and awards prizes by chance is an illegal lottery in most states; a legitimate sweepstakes must offer a free method of entry ("no purchase necessary") and clear official rules, with state registration and bonding required in some states (Florida and New York are perennial examples) for larger prizes. Skill-based contests are treated differently. State law dominates here.

"New" claims. Generally, a product should not be advertised as "new" for more than about six months after introduction, and certain categories (e.g., retreaded tires, reprocessed textiles) have specific rules.

Subliminal advertising. Embedding hidden messages intended to influence behavior would be deceptive — though, reassuringly for consumers and amusingly for marketers, the consensus is that it does not actually work.

Penalties, Remedies, and the State-Law Overlay

What can actually happen to a company that runs a false or deceptive ad?

The consequences scale with the violation, the harm, and which law you tripped. The toolkit includes:

  • Cease-and-desist / consent orders. The FTC's bread and butter. These legally binding orders stop the practice, often require substantiation and reporting for future ads, and — crucially — make future violations subject to civil penalties (the per-violation, per-day maximum is adjusted annually for inflation and currently exceeds $50,000 per violation). A consent order can bind a company for twenty years.
  • Civil penalties. Available where a specific rule with penalty authority is violated (the Made in USA Rule, CAN-SPAM, COPPA, the TSR, the 2024 fake-review rule) or where a respondent violates an existing order. These run from thousands to many millions.
  • Consumer redress and restitution. Refunds and monetary relief to harmed consumers. Note an important wrinkle: in AMG Capital Management, LLC v. FTC, 593 U.S. 67 (2021), the Supreme Court held the FTC cannot get equitable monetary relief directly under Section 13(b), pushing the agency toward slower routes (a final cease-and-desist order plus Section 19, or rule-based penalty authority). This is precisely why the FTC has been so busy promulgating rules with built-in penalty teeth.
  • Corrective advertising and disclosures. In serious cases, an advertiser can be ordered to run new ads correcting the prior misimpression.
  • Private and competitor remedies. Lanham Act injunctions and damages from competitors; class actions and statutory or treble damages and attorney's fees under state UDAP statutes and the TCPA.

How do the fifty-state consumer-protection statutes change my analysis?

Profoundly, and many businesses learn this the hard way. Every state has a UDAP statute — a "little FTC Act" prohibiting unfair and deceptive practices, often interpreted in light of FTC precedent. But the details vary enormously: many states allow private lawsuits (the federal FTC Act does not), many authorize class actions, and many provide statutory damages, treble damages, and attorney's fees that make even small-dollar claims worth a plaintiff's lawyer's time. California's Unfair Competition Law (Bus. & Prof. Code § 17200) and False Advertising Law (§ 17500), Massachusetts's Chapter 93A, New York's General Business Law §§ 349–350, and Florida's FDUTPA are perennial sources of litigation. On top of these sit topic-specific state laws — automatic-renewal statutes, deceptive-pricing rules, "Made in USA" laws (California's is stricter than the federal standard), green-marketing rules, and more. The practical upshot: clearing your ad under federal law is necessary but not always sufficient. If you advertise nationally, you are advertising into fifty regulatory environments at once.

Can an ad agency or an influencer be on the hook, not just the brand?

Yes. The FTC and the courts can reach advertising agencies that participated in creating an ad and knew or should have known it was deceptive — an agency cannot simply rely on the client's say-so and must make an independent check of substantiation. The same logic now reaches influencer-marketing firms and intermediaries, and individual influencers can be liable for their own deceptive or undisclosed endorsements. Liability follows participation and knowledge, not just whose name is on the product. This is one more reason a brand should document its substantiation, its endorsement policy, and its monitoring program: when the FTC asks who knew what, your file answers the question.

A Practical Compliance Checklist for Small Businesses

Because advertising law rewards process, here is a workable routine to run before any campaign goes live. Treat it as a true checklist — one of the few places bullet points earn their keep.

  1. List every claim, express and implied — and read for net impression. Read your ad as a skeptical stranger. Write down not just what it says, but every reasonable impression it leaves (remember the ~15% threshold). Substantiate all of them.
  2. Match each claim to evidence in hand — now, not later. Fit the evidence to the claim type: technical testing for performance, consumer testing for sensory/perception claims, competent and reliable scientific evidence for health/safety and establishment claims, head-to-head testing at the 95% confidence level for comparative claims, market-basket testing for dangling comparisons. File the substantiation.
  3. Check the words that trigger rules. "Free," "new," "sale/was," "Made in USA," "eco-friendly/recyclable/biodegradable," "clinically proven," "guaranteed," "lowest price," "results" — each invokes a specific framework above.
  4. Audit disclosures for clarity and conspicuousness. Material connections (#ad, sponsored), native-ad labels, "free" offer terms, credit/lease triggering terms, auto-renewal terms, sweepstakes rules. Place them near the claim, in plain language, unavoidable — not in a thicket of hashtags, a bio, or six-point fine print that contradicts the headline.
  5. Vet your delivery channel and your billing. Email (CAN-SPAM opt-outs and physical address), texts/calls (TCPA written consent — get it documented), telemarketing (TSR), subscriptions (ROSCA/state ARLs, easy cancellation, no dark patterns), kids (COPPA verifiable parental consent).
  6. Run the competitor and self-regulation gut check. Would this survive a Lanham Act suit or an NAD challenge? Are your own claims clean enough to avoid a counterclaim? Would you want to defend it to a state AG?
  7. Map the state overlay. Identify where you are advertising and whether any state (California especially) imposes a stricter rule on your specific claim or practice.
  8. Document and keep records. Substantiation files, consent logs, opt-out records, your endorsement policy and monitoring logs, and a dated copy of the ad. If you ever have to answer that unsmiling letter, your file is your best friend.

When the stakes are high — a national campaign, a regulated product, a bold comparative claim, or anything touching health, finance, or children — get qualified counsel to review before you launch. A short pre-launch review is far cheaper than a consent order. To understand which kind of lawyer to call, see types of lawyers.

Key Takeaways

If you remember nothing else, remember these.

Advertising law is fundamentally about the gap between what your ad communicates — including its implications and net impression — and what you can prove. Close that gap with substantiation you hold before the ad runs, matched in kind to the claim you are making. Section 5 of the FTC Act demands truth, substantiation, and fairness; the reasonable-consumer lens (with its roughly 15% threshold) and the implied-claim and net-impression doctrines mean you are responsible for impressions you may never have intended. Endorsements and influencer posts require honest opinions and clear, conspicuous disclosure of any material connection, under the toughened 2023 Guides and the penalty-bearing 2024 fake-review rule, and the brand is expected to train and monitor its endorsers. Specific claims — "Made in USA," green claims, pricing, "free," and comparative claims — each carry their own substantiation and disclosure expectations, and the wrong word choice can trigger civil penalties or a competitor's Lanham Act suit. The channel you use carries its own per-message-damages and billing regimes: CAN-SPAM for email, the TCPA for texts and calls, the TSR for telemarketing, ROSCA and the state ARLs for subscriptions, and COPPA for kids. And federal compliance is a floor, not a ceiling — fifty state UDAP statutes, many with private rights of action and class-action exposure, sit on top. Build a pre-launch process, document everything, and bring in counsel for the high-stakes campaigns.

Frequently Asked Questions

Do I really have to substantiate a claim before the ad runs, even if the claim is true? Yes. The violation is making a claim without a reasonable basis, independent of whether the claim later proves accurate. You must possess competent, objective evidence appropriate to the claim at the moment the ad is disseminated. For health, safety, and "establishment" claims (those that tout a level of proof), that means competent and reliable scientific evidence, in hand, before publication.

Will the FTC pre-clear my ad so I know it's safe? No. The FTC does not review or approve ads in advance. It does publish extensive free guidance — policy statements, rules, business guides, and FAQs at ftc.gov — and you can study its prior enforcement actions involving similar products or claims. For anything significant, a pre-launch review by qualified counsel is the practical substitute for clearance.

An influencer is posting about my product in exchange for free samples. Do they need to say "#ad"? Yes. Free product is a "material connection" that consumers would not necessarily expect, so the post needs a clear, conspicuous disclosure (such as #ad, "Sponsored," or "Thanks to [Brand] for the free sample") in the post itself, proximate to the endorsement — and in a video, within the video where the endorsement is made, displayed long enough to read. Under the 2023 Endorsement Guides, you as the brand share responsibility and are expected to adopt a written endorsement policy and to train and monitor your endorsers. See social media law basics for the broader picture.

A competitor is running an ad I'm sure is false. What can I do? You have several options, often in combination: call or send a demand letter to the competitor; ask the media outlet running it to pull it under its advertising standards; file a challenge with the National Advertising Division (faster and cheaper than court, with a 20-business-day "Fast-Track SWIFT" option for disclosure and simple-claim disputes); report it to the FTC or a state Attorney General (regulators won't referee a pure competitor dispute but use complaints to spot patterns); or sue under Section 43(a) of the Lanham Act (the only route that offers an injunction). First, audit your own claims so you don't invite a counterclaim. False advertising and Lanham Act Section 43(a) explains the litigation path.

Can I say my product is "Made in USA" if I assemble it here from imported parts? Not as an unqualified claim. "Made in USA" requires the product to be "all or virtually all" made domestically, and final assembly of imported components usually does not meet that bar — and even "Assembled in USA" is deceptive if the assembly is a trivial last step. The Made in USA Labeling Rule (16 C.F.R. Part 323) carries civil penalties (roughly $43,792 per violation), and the FTC enforces it. You can make an accurate qualified claim instead, such as "Made in USA of U.S. and imported parts," while also satisfying Customs and Border Protection's separate marking rules.

Is "eco-friendly" a safe thing to put on my packaging? It's risky. Broad, unqualified green claims like "eco-friendly," "green," or "sustainable" are very hard to substantiate under the Green Guides (16 C.F.R. Part 260) because they imply a sweeping environmental benefit. Tie any environmental claim to a specific, substantiated attribute — e.g., "made with 30% recycled content" — make clear whether it covers the product, the packaging, or both, and check state law, since California and others regulate terms like "recyclable" and "compostable" by statute.

If I send marketing texts, what's my real exposure if I get consent wrong? Potentially severe. The TCPA provides $500 in statutory damages per violating text, trebled to $1,500 for willful violations — per message — and is a frequent class-action vehicle. Get documented prior express written consent before texting, honor opt-outs immediately, and check whether any state mini-TCPA imposes additional requirements. A 10,000-message campaign sent without proper consent is a multimillion-dollar liability on paper.

My business runs on subscriptions. What's the one thing I must get right? Make canceling at least as easy as signing up, and disclose every material term and obtain express consent before you take billing information. ROSCA (for online plans), the state automatic-renewal laws (California's is the strictest), and the FTC's Section 5 authority all converge on that point, and the FTC treats cancellation-obstructing "dark patterns" as unlawful. Document the disclosures the customer saw and the consent they gave.

Does federal compliance mean I'm in the clear everywhere? No. Federal law is a floor. Every state has its own consumer-protection (UDAP) statute, many allowing private and class-action suits with statutory or treble damages and attorney's fees, and many states have stricter topic-specific rules (auto-renewal, deceptive pricing, "Made in USA," green marketing). If you advertise nationally, you must consider the state overlay, especially California.

What about marketing to children? Marketing aimed at children under 13 that collects personal information triggers COPPA (15 U.S.C. §§ 6501–6506), which requires verifiable parental consent, a clear privacy policy, data minimization, and security — with substantial penalties and a 2025 rule update tightening the standards (including limits on targeted advertising to kids). Advertising content directed at children is also judged from a child's perspective and is subject to CARU's influential self-regulatory guidelines. Build compliance in before launch.
