FTC Endorsement Rules for Product Sellers: Reviews, Affiliates, and Influencer Campaigns

For fourteen years, the FTC's rules on endorsements sat largely unchanged. That ended in October 2023, when the Commission issued the first major revision to 16 CFR Part 255 since 2009. The update addressed five core areas: expanding the scope of covered conduct, tightening disclosure requirements, clarifying accuracy obligations, outlining liability for advertisers and intermediaries, and protecting consumer review integrity. Tagging a brand on social media now explicitly counts as an endorsement under the revised text.

The new definition of "clear and conspicuous" at 16 CFR § 255.0 carries a medium-matching requirement with real teeth. A disclosure must be "difficult to miss (i.e., easily noticeable) and easily understandable by ordinary consumers," and in interactive electronic media — including social platforms — it must be unavoidable. A hashtag buried below a caption, or a verbal mention on a video with no on-screen text, does not satisfy this standard.

The enforcement stakes rose at the same time the rules expanded. Following AMG Capital Management v. FTC (2021), the Supreme Court held unanimously that Section 13(b) does not authorize equitable monetary relief, including restitution and disgorgement. The FTC responded by leaning on Section 18 rulemaking, which carries per-violation civil penalties. The Commission put over 700 companies on notice that violations could run approximately $50,000 per violation — and made clear that advertisers, not just their influencers, are responsible for monitoring what their endorsers say and do.

A companion rule on consumer reviews (16 CFR Part 465), effective October 21, 2024, added a separate civil-penalty mechanism targeting fake and suppressed reviews, with fines up to $51,744 per violation. For DTC brands running affiliate programs, seeding products with creators, or soliciting customer reviews, these two regulatory instruments now define the floor below which no piece of sponsored content, affiliate link, or review request can fall.

Material Connections: What Triggers a Disclosure Obligation

Before asking how to disclose, you need to know when disclosure is required. Under 16 CFR § 255.5, a material connection is any relationship between an endorser and a brand "that might materially affect the weight or credibility of the endorsement" and that a significant minority of the target audience would not reasonably expect. The regulation covers a broad range of triggers: payment, free or discounted products, early access, affiliate commissions, employment, and personal or family relationships. If the connection exists and the audience would not assume it unprompted, disclosure is required.

Affiliate links are a per se material connection. Receiving a commission on a sale — regardless of the commission rate or dollar amount — materially affects reviewer credibility by definition. § 255.5 Example 11 makes this explicit: any content containing an affiliate link requires a disclosure in or before that content, every time. The size of the payout does not create an exception, and neither does the creator's follower count. FTC requirements apply to nano-influencers and micro-creators on the same terms as accounts with millions of followers.

Product seeding creates a compliance obligation for the brand even when the brand never instructs the creator to post. Under the 2023 guides, advertisers are responsible for monitoring the conduct of their endorsers — and that responsibility does not evaporate because the brand stayed silent on disclosure. If a brand sent a free product knowing the creator would post about it, the brand owns the compliance gap when that post goes up without a disclosure. Brands that repost influencer content they know is deceptive face additional liability on top of that. The practical implication: any gifting or seeding program needs a disclosure requirement baked into the outreach itself, not treated as the creator's problem.

The 2023 revision also expanded what counts as an endorsement in the first place. Tagging a brand positively on social media, when a material connection exists, is now expressly treated as an endorsement requiring disclosure, even if the post contains no written review language. For DTC brands running FTC-compliant influencer programs, that means the obligation attaches at the tag, not just when the creator writes a caption. A creator who receives free product and then tags the brand in a photo without any disclosure text has already triggered a violation.

How to Disclose: Placement, Proximity, and Clarity

"Clear and conspicuous" is not a tone standard — it is a placement standard. Under 16 CFR § 255.0, a disclosure in interactive electronic media must be unavoidable, use the same medium as the endorsement, and not be contradicted or mitigated by anything else in the communication. That language sets a mechanical floor, and several common approaches fall below it.

A bio disclosure does not count. Putting "#ad for all sponsored content" in an Instagram bio does not satisfy the obligation for individual posts — the FTC's guidance is explicit that disclosure must appear in each specific piece of content where the endorsement occurs. Similarly, a disclosure that appears only after the endorsement content, buried in a hashtag cluster, or hidden below a "more" button fails the standard because a viewer who stops reading before that point never saw it. For Instagram Stories and other image-based ephemeral formats, the disclosure must be superimposed over the image itself, with enough time on screen for viewers to notice and read it.

Platform-native tools are not a substitute. Instagram's Paid Partnership label and TikTok's Sponsored Content toggle can supplement a creator's own disclosure, but the FTC's position is that they do not replace it. Brands that rely solely on a platform toggle without requiring explicit language in the caption or video itself have not closed the compliance gap.

On language, the FTC's Disclosures 101 guidance draws a clear line. Acceptable: "Ad," "Paid partnership," "#sponsored," "I got this free from [Brand]." Not acceptable: "spon," "sp," "collab," "ambassador" standing alone, "#love," or "#thanks" — abbreviated or vague terms that ordinary consumers would not recognize as commercial disclosures.

For affiliate links specifically, disclosure must appear near or before the link, not on a separate disclosures page. "Paid link" satisfies the standard; "commissionable link" or "affiliate link" alone may not, because ordinary consumers do not know what those terms mean.

Review Gating Is Illegal — The CRFA and the FTC's Position

Disclosure obligations govern what endorsers say. A separate set of rules governs what brands do to the review pool itself. Review gating — sending a satisfaction survey first, then routing high-scorers to Google or Amazon while sending low-scorers to a private complaint form — is, in the FTC's words, "a material misrepresentation of the business's true reputation." The mechanics vary, but the legal conclusion does not.

Two instruments make review gating illegal. First, the Consumer Review Fairness Act (CRFA), 15 U.S.C. § 45b, prohibits any form contract provision that restricts a consumer from posting a review, imposes a penalty for doing so, or requires the consumer to transfer intellectual property rights in their review. The CRFA is enforced by the FTC as an unfair or deceptive practice. Second, 16 CFR Part 465 § 465.7, effective October 21, 2024, independently prohibits "processes preventing or removing unfavorable reviews" — going beyond contract terms to reach operational practices — with civil penalties up to $51,744 per violation.

The Fashion Nova enforcement action is the clearest illustration of where this leads. From late 2015 through November 2019, Fashion Nova used a third-party review platform that automatically posted four- and five-star reviews to its website while holding lower-starred reviews for company approval. Fashion Nova never approved or posted hundreds of thousands of those suppressed reviews. In January 2022, the FTC extracted a $4.2 million settlement under Section 5 of the FTC Act — the first time the Commission had challenged review suppression directly. The consent order requires Fashion Nova to post all product reviews for items currently on sale, with only narrow exceptions for obscene, unlawful, or product-unrelated content.

The Sunday Riley case covers the other side of the same manipulation problem: fabricating the positive reviews rather than burying the negative ones. Between November 2015 and August 2017, Sunday Riley managers — acting on the CEO's direct instruction by email — created fake consumer personas, used a VPN to avoid detection, posted five-star reviews on Sephora.com, and flagged negative reviews as unhelpful. The 2019 FTC consent order followed. Together, Fashion Nova and Sunday Riley bracket the two enforcement theories: suppressing real negative reviews and manufacturing fake positive ones. Both are violations.

Compliance Checklist for Affiliate and Influencer Programs

The rules covered in this guide do not become compliant through a single contract clause. FTC compliance for endorsement programs is operational — it requires the right agreements, ongoing monitoring, and a disciplined approach to review solicitation. The checklist below consolidates the practical steps for each program type.

Affiliate and Influencer Programs

Your agreements are the foundation, but agreements alone are not a defense. The FTC's position, echoed in enforcement actions, is that brands bear responsibility for what affiliates and influencers publish. Contracts should spell out approved disclosure language, platform-specific implementation requirements, and consequences for noncompliance. Claiming you did not know what an influencer posted does not insulate the brand from liability.

• Agreements: Include FTC disclosure requirements in every affiliate and influencer contract, specifying approved disclosure language and platform-by-platform implementation.
• Affiliate links specifically: Monitor affiliate content to confirm that disclosure language is placed near or before each affiliate link, using consumer-legible phrasing — "paid link" or "I earn a commission" qualifies; "affiliate link" alone may not, because consumers often do not know what it means.
• Briefing and direction: Do not brief influencers in a way that discourages or omits disclosure. Sending free product with instructions to post, without disclosure guidance, is a compliance gap the brand owns.
• Monitoring and documentation: Audit affiliate and influencer content regularly. Pre-approval workflows and documented spot-checks are baseline controls.
• Insider posts: Officers, managers, and employees who post publicly about the business's products must clearly disclose their material relationship — this obligation applies to their personal social media accounts, not only brand channels.

Review Solicitation and Testimonial Programs

Two rules govern incentivized review programs: you can ask all customers for a review, and you can offer an incentive for an honest review — but the incentive cannot be conditioned on what the review says. Offering a discount for a five-star review violates 16 CFR Part 465 § 465.4. Offering a discount for any honest review, requiring only that the reviewer disclose the incentive, is permissible. The distinction is sentiment-neutrality, not whether an incentive exists at all.

• Solicitation: Invite all customers to leave reviews, not a pre-screened subset. Filtering by satisfaction level before extending a review invitation is review gating — a CRFA violation.
• Incentives: Tie any incentive to review completion and honesty, never to a minimum star rating or positive sentiment.
• On-site testimonials: If your website displays testimonials from compensated customers or employees, each testimonial must include a material connection disclosure. Selectively featuring only positive testimonials from a broader solicitation program creates an implied misrepresentation.

Legacy Content

Existing undisclosed endorsements do not age out of FTC exposure. Live posts from prior seeding campaigns or affiliate relationships that lack compliant disclosures remain an active compliance problem regardless of when they were published. Audit your existing influencer and affiliate content, add disclosures to posts that lack them, and remove posts where disclosure is not possible or practical.
