Affiliate Disclosure: FTC Requirements Every Blogger and Influencer Must Follow

If you recommend products on your blog, YouTube channel, social media, or website and earn a commission when someone makes a purchase through your link, the Federal Trade Commission (FTC) requires you to disclose that relationship. Failure to do so can result in enforcement actions and reputational damage. This guide explains what the law actually says, who it applies to, and the practical steps for staying compliant.

This article is general information about advertising-disclosure rules, not legal advice. Laws vary by jurisdiction and change over time. For guidance on your specific situation, consult a qualified attorney.

What Is an Affiliate Disclosure?

An affiliate disclosure is a statement that informs your audience you may earn a commission from purchases made through links on your site. It's fundamentally about transparency — letting readers know your recommendations may be financially motivated so they can weigh that information for themselves.

Who Has to Disclose?

The duty to disclose is broad. Under the FTC's Endorsement Guides, an "endorsement" is any marketing message that consumers are likely to believe reflects the opinions or experience of someone other than the advertiser — and that includes verbal statements, demonstrations, and even tags in social media posts. If you publish a product recommendation and have a financial stake in the sale, you are an endorser with a disclosure obligation. This covers full-time influencers, hobby bloggers, and businesses promoting their own products alike.

Why Are Affiliate Disclosures Required?

• FTC Endorsement Guides: The Guides require that a "material connection" between an endorser and a brand be disclosed when the audience wouldn't reasonably expect it. The regulation states that such a connection "must be disclosed clearly and conspicuously," and that material connections "can include monetary payment or the provision of free or discounted products," regardless of whether the advertiser requires an endorsement in return. Commission from an affiliate link is exactly that kind of connection.
• Consumer protection: The Endorsement Guides interpret Section 5 of the FTC Act, which prohibits "unfair or deceptive acts or practices." Recommendations that hide a financial motive can mislead readers, which is why undisclosed affiliate relationships fall within the conduct the Commission can act against.
• Amazon Associates requirement: Amazon's affiliate program separately requires participants to state that they earn from qualifying purchases. Failing to follow the program's operating agreement can result in account termination — a contractual risk on top of the legal one.
• International regulations: Other countries have comparable rules. In the UK, the Competition and Markets Authority tells content creators plainly that "it is not enough just to tag a brand in your post, use discount codes or affiliate links" — incentivised content must be clearly identifiable as an ad. If your audience reaches into other markets, those regimes may apply too.

FTC Disclosure Rules — What You Need to Know

1. Disclosures Must Be Clear and Conspicuous

"Clear and conspicuous" is a defined legal term, not a vibe. The FTC's Endorsement Guides define it to mean that a disclosure is "difficult to miss (i.e., easily noticeable) and easily understandable by ordinary consumers." In practice that means your disclosure should be:

• Easy to notice: Not buried in a footer or hidden behind a link. It should sit with the recommendation, near the affiliate links themselves.
• Easy to understand: Use plain language. "This post contains affiliate links" beats dense legal jargon.
• Hard to miss: Use clear formatting — bold text, a distinct paragraph, or a visible banner — and match the medium. The Guides note that a visual disclosure should stand out by its size, contrast, and location.

The Endorsement Guides include an example aimed squarely at affiliate blogging: a coffee blogger who writes independent reviews but includes affiliate links. The Commission's conclusion is that because the commission "could affect the weight or credibility site visitors give to the blogger's reviews, the reviews should clearly and conspicuously disclose the compensation."

2. Placement Matters

Where the disclosure sits is as important as what it says. FTC staff guidance for creators advises placing the disclosure with the endorsement message itself and warns that disclosures "are likely to be missed if they appear only on an ABOUT ME or profile page, at the end of posts or videos, or anywhere that requires a person to click MORE." Best practices:

• Place a brief disclosure at the top of blog posts that contain affiliate links, before the reader hits the first link
• Include a more detailed affiliate disclosure page linked from your site's menu or footer (as a supplement, not a substitute)
• On social media, include the disclosure in the post itself — not just in your bio
• In videos, put the disclosure in the video, not only in the description; the FTC notes viewers are more likely to notice a disclosure made in both audio and on screen

3. Every Platform, Every Post

Disclosures are required on every platform where you use affiliate links: blog posts, YouTube videos, Instagram stories, TikTok videos, Twitter threads, email newsletters, and podcasts. FTC staff are explicit that it is the creator's job: "it's your responsibility to make these disclosures... Don't rely on others to do it for you." A disclosure on your website's About page doesn't cover your social posts, and the Guides confirm that satisfying the rule in one piece of content "has no bearing" on whether you must disclose in another.

4. "I Didn't Think They'd Mind" Is Not a Defense

A common misconception is that disclosure is only needed when a recommendation is paid-per-post or when followers might be surprised. The Guides are stricter: a connection must be disclosed when even "a significant minority of the audience" does not understand or expect it. FTC staff put it bluntly for creators: "Don't assume your followers already know about your brand relationships," and make a disclosure "even if you think your evaluations are unbiased." Free products count the same as cash — the obligation applies whether you were paid, gifted, or simply earn commission on a sale.

What a Good Affiliate Disclosure Looks Like

Here's a clear, concise example for a blog post:

"Disclosure: Some of the links in this article are affiliate links, meaning I may earn a commission at no additional cost to you if you make a purchase. I only recommend products I genuinely believe in."

On space-limited platforms, the FTC accepts simple terms like "ad" or "sponsored" — and even brand-partner labels such as "AcmePartner" — provided they're placed where they're hard to miss.

A Practical Compliance Checklist

• Put the disclosure up front. Before the first affiliate link in a post, not at the very bottom.
• Use it everywhere you link. Each blog post, video, story, and email that carries affiliate links needs its own disclosure.
• Say it in plain words. The reader should understand it on first read, without clicking anything.
• Keep your reviews honest. The Guides also prohibit endorsing a product you haven't used or claiming benefits the advertiser can't substantiate — disclosure doesn't cure a deceptive claim.

Common Mistakes to Avoid

• Only disclosing on one page: A single "affiliate disclosure" page is not enough. You must disclose on every page or post that contains affiliate links.
• Using vague or shorthand labels: FTC staff specifically warn against "vague or confusing terms like 'sp,' 'spon,' or 'collab,'" and against stand-alone words like "thanks" or "ambassador." Stick to clear terms such as "ad" or "sponsored."
• Burying the disclosure in a wall of hashtags: The FTC advises against mixing your disclosure "into a group of hashtags or links" where it's easy to scroll past.
• Hiding disclosures: Placing them in fine print, footer-only areas, or behind "read more" links cuts against the clear-and-conspicuous standard.
