FTC Disclosure Rules for Brand Posts and AI Replies on Social Media

Short answer, as of 2026-10-16: under the FTC's Endorsement Guides (16 CFR Part 255), any post or reply that readers are likely to take as someone else's opinion of your product needs a clear, unavoidable disclosure of any material connection to you that readers would not expect. A post from an account that is plainly your brand is your own advertising, not an endorsement. The FTC's 2024 rule on reviews and testimonials (16 CFR Part 465) adds a hard ban on reviews from people who do not exist. Neither text has a separate chapter on AI. What counts is who the reader thinks is talking.

What the two FTC texts are

The Guides Concerning Use of Endorsements and Testimonials in Advertising are the FTC's interpretation of section 5 of the FTC Act. The current text dates from July 26, 2023 (88 FR 48102). The FTC's own Q&A on the Guides is direct about their status:

“The Guides themselves don’t have the force of law.”

The same page adds that practices inconsistent with the Guides can still lead to enforcement under section 5.

The Rule on the Use of Consumer Reviews and Testimonials is a rule, not guidance. It was published on August 22, 2024 (89 FR 68077). In its announcement, the FTC said the rule lets it seek “civil penalties against knowing violators.”

On reach, the FTC's Disclosures 101 for Social Media Influencers says: “If posting from abroad, U.S. law applies if it's reasonably foreseeable that the post will affect U.S. consumers.”

When a brand post counts as an endorsement

Section 255.0(b) defines an endorsement as a promotional message

“that consumers are likely to believe reflects the opinions, beliefs, findings, or experiences of a party other than the sponsoring advertiser”

The test is the reader's belief, not the tool that wrote the words. An example in the same section describes a spokesperson who speaks “in the place of and on behalf of” a company, not from personal experience. That is not an endorsement. A reply from an account clearly named as your brand works the same way: readers know the brand is talking.

It changes when the account does not look like the brand. Section 255.5(a) says a connection that “might materially affect the weight or credibility” of an endorsement, and that the audience would not expect, must be disclosed clearly and conspicuously. Its list of material connections includes business, family and personal relationships, payment, and free or discounted products.

Example 8 in section 255.5 is close to community marketing. An employee of a robot maker promotes the company's new product on a discussion board without saying where they work. The Guides say the employee should disclose the relationship, and the employer should train employees and monitor posts it directed or knows about. Section 255.1(f) adds that agencies, PR firms and other intermediaries may also be liable when they spread endorsements without needed disclosures, or hire and direct endorsers who skip them.

What “clear and conspicuous” means on social media

Section 255.0(f) says a clear and conspicuous disclosure is “difficult to miss (i.e., easily noticeable) and easily understandable by ordinary consumers.” For social media and the internet, it says the disclosure “should be unavoidable.” The 2024 rule's own definition, in section 465.1(c)(4), is stricter in wording:

“A disclosure is not clear and conspicuous if a consumer must take any action, such as clicking on a hyperlink or hovering over an icon, to see it.”

The examples in the Guides and the FTC's guidance pages make that concrete:

• Put it in the post, not only in the bio. Disclosures 101: “The disclosure should be placed with the endorsement message itself.”
• Not behind “more.” Example 9 in section 255.0 says a disclosure hidden behind a “more” link is not unavoidable.
• Put it near the start. The Q&A says: “A disclosure in the middle or at the end of a post is easier to miss and thus less likely to be effective.”
• Do not rely only on a platform's label. Example 9 describes a built-in disclosure in small white text on a light image, shown for five seconds, as easy to miss. The Q&A advises adding your own disclosure anyway.
• Use plain words. The Q&A says “There is nothing special about hashtags from a disclosure perspective,” and that “Sponsored by XYZ” or “Promotion by XYZ” would be clearer than a bare “Sponsored.”
• Match the language and the device. Example 11 in section 255.0 says a disclosure must be in the same language as the ad and must work on a smartphone too, not only in a desktop browser.
• In video, put it in the video. In a live stream, Disclosures 101 says it “should be repeated periodically” for viewers who join late.

AI replies, fake reviewers and the 2024 rule

In the eCFR text checked on 2026-10-16, neither Part 255 nor Part 465 uses the words “artificial intelligence” or “AI.” The FTC's announcement of the 2024 rule does. It says the rule covers reviews and testimonials that “misrepresent that they are by someone who does not exist” and gives “AI-generated fake reviews” as an example.

The parts of the rule that matter most for AI-drafted replies:

• Section 465.2(a): a business may not write, create or sell a consumer review or testimonial that misrepresents that the reviewer exists, that they used the product, or what their experience was. An agent that writes “I switched to this last month and love it” for a brand, as if it were a customer, is the case this section describes.
• Section 465.4: no paying for or rewarding reviews that are conditioned on a positive or negative sentiment.
• Section 465.5: officers and managers who review their own company's products must clearly disclose the relationship.
• Section 465.8: no buying or selling fake indicators of social media influence. Section 465.1(h) counts indicators generated by “bots, purported individual accounts not associated with a real individual,” or hijacked accounts.

In short: an AI agent replying from your brand's labelled account is your brand speaking. An agent posing as an independent person is what both texts treat as deceptive.

A checklist for brand-run accounts

1. Make the handle and display name say it is your brand, so every reply reads as the brand speaking.
2. When an employee, founder or agency posts from a personal account, put the connection in the post itself, such as “I work at Acme.” The Q&A says: “Listing your employer on your profile page isn’t enough.”
3. Do not let AI drafts claim personal use or customer experience. Section 255.1(c) says an endorser who claims to use a product must actually have used it.
4. When you give creators free products or pay them, tell them to disclose, monitor what they post and act on gaps. That is the three-step duty in section 255.1(d).
5. When you repost a creator's post, add your own disclosure if theirs is missing or does not carry over. Example 3 in section 255.5 covers exactly this.
6. Check each disclosure on a phone and in every language you post in.
7. Never buy reviews tied to a sentiment, and never buy followers, likes or views.

What this does not cover

This is not legal advice. It covers two US federal texts and the FTC's own guidance pages, as of 2026-10-16. It does not cover state law, other countries' rules, or each platform's own terms. Footnote 1 of section 255.0 notes that FTC staff guidance is updated periodically and is not binding on the Commission, so check the linked pages before you rely on them.
