FTC Affiliate Disclosure Rules: What Marketers Need to Do

FTC endorsement guides require anyone promoting a product or service through an affiliate link to clearly disclose that relationship to their audience, before or alongside the content, not buried in a footer. The rules apply whether you are a solo blogger, a media brand, or a large publisher running an affiliate programme at scale. Getting this wrong is not just a compliance risk, it is a trust problem that tends to compound quietly until it becomes a serious one.

The FTC updated its Endorsement Guides in 2023, tightening the language around what counts as adequate disclosure and expanding its guidance on social media, video, and influencer content. If your affiliate programme is still running on 2015-era assumptions about what a disclosure needs to look like, this article is worth your time.

Why Affiliate Disclosure Is a Business Problem, Not Just a Legal One

I have sat in enough agency boardrooms to know how compliance conversations usually go. Someone from legal flags a regulatory requirement, the room nods, someone adds it to a checklist, and the actual business implications get approximately thirty seconds of attention. That is the wrong way to think about FTC disclosure requirements for affiliate marketing.

The disclosure question is fundamentally a trust question. When someone reads a product recommendation on a site you run, or that one of your affiliates runs, they are making a judgment call about whether that recommendation is honest. If they later discover there was a financial relationship they were not told about, the damage is not to the FTC filing. The damage is to the relationship between that publisher and their audience, and by extension, to your brand.

Affiliate marketing is one of the more commercially interesting channels in the partnership marketing toolkit, precisely because it aligns incentives around outcomes rather than activity. But that alignment only holds if the audience trusts the publisher. Disclosure, done properly, is what protects that trust. If you want to understand how affiliate fits into a broader partnership strategy, the Partnership Marketing hub covers the full picture.

What the FTC Endorsement Guides Actually Say

The FTC’s Endorsement Guides (formally, 16 CFR Part 255) are not new. They have existed in some form since 1980. But the 2023 revision is the most significant update in over a decade, and it addressed several areas where enforcement had lagged behind actual practice.

The core principle has not changed: if there is a material connection between an endorser and the brand they are promoting, that connection must be disclosed. A material connection is anything that could affect the weight a consumer gives to the endorsement. An affiliate commission is clearly material. A free product is material. A paid partnership is material. Even a close personal or professional relationship can be material if it would change how someone reads the recommendation.

What changed in 2023 is the specificity around what adequate disclosure looks like. The FTC made clear that:

• Disclosures must be clear and conspicuous, meaning a reasonable person would notice them and understand them
• Disclosures must be placed near the endorsement itself, not in a general site disclaimer or a footer
• On video content, disclosures must appear at the start of the video, not only at the end
• On social media, disclosures embedded only in hashtags or placed after a “more” break are not adequate
• Brands are responsible for ensuring their affiliates and influencers are disclosing properly, and cannot simply disclaim liability by pointing to a terms and conditions document

That last point is the one most brands are not taking seriously enough. If you are running an affiliate programme and your publishers are not disclosing, you are exposed, not just them.

What Counts as a Clear and Conspicuous Disclosure

The FTC does not mandate specific language, which is both useful and occasionally frustrating. The standard is whether a typical consumer would notice the disclosure and understand what it means. In practice, that means the following approaches are generally adequate for written content:

• “This post contains affiliate links. If you buy through them, I may earn a commission at no extra cost to you.”
• “Affiliate disclosure: I earn a small commission on purchases made through links in this article.”
• A clearly labelled “Affiliate Disclosure” section at the top of the page, before the content begins

What is not adequate: a disclosure buried at the bottom of a long page, a disclosure in a sidebar that most readers will never see, or language so vague that a reader would not understand it signals a financial relationship. “This site uses affiliate links” in a footer does not cut it. Neither does “some links may be compensated” without explaining what that means.

For social media, the FTC has been explicit that platform-native disclosure tools (like Instagram’s “Paid partnership” tag) can be adequate, but only if they are actually visible and not obscured by other content. Hashtags like #ad or #sponsored are generally acceptable on social platforms if they appear prominently, not buried in a string of ten other hashtags at the end of a caption.

For video content, the disclosure needs to be both verbal and visual at the start of the video. A text card at the end of a five-minute review does not satisfy the requirement. Neither does a single spoken line in the middle of the video that a viewer might miss.

How Brand Responsibility Works in Affiliate Programmes

When I was running agencies, one of the things I saw repeatedly was brands treating their affiliate programmes as essentially hands-off channels. You set up the tracking, you agree the commission structure, you approve publishers into the programme, and then you let them get on with it. The assumption was that compliance was the publisher’s problem.

That assumption has always been legally questionable, and the 2023 FTC guidance makes it even harder to sustain. The Guides are explicit that brands (referred to as “advertisers” in FTC language) have an obligation to monitor their affiliate partners for compliance and to take action when they find violations. Simply having a disclosure requirement in your affiliate agreement is not sufficient if you are not actually enforcing it.

In practical terms, this means brands running affiliate programmes should be doing the following:

• Including clear disclosure requirements in affiliate agreements, with specific examples of what adequate disclosure looks like
• Conducting periodic audits of affiliate content, particularly for high-volume partners
• Providing affiliates with disclosure language they can use, rather than leaving them to figure it out themselves
• Having a process for addressing non-compliance, including removing publishers from the programme if they repeatedly fail to disclose

Some of the better-run affiliate programmes I have seen treat disclosure as part of onboarding rather than an afterthought. Later’s affiliate programme, for example, provides partners with resources that include guidance on how to promote the product compliantly. That is the right approach: make it easy for affiliates to do the right thing, rather than assuming they will figure it out.

The 2023 Updates and What They Changed in Practice

The 2023 revision to the Endorsement Guides addressed several areas where the original guidance had not kept pace with how marketing actually works now. A few are worth flagging specifically.

Fake reviews and review gating. The updated Guides explicitly address the practice of incentivising positive reviews while suppressing negative ones. If you are offering rewards for reviews, those reviews must be disclosed as incentivised. More importantly, you cannot condition the incentive on the review being positive, and you cannot selectively publish only the positive reviews you receive.

AI-generated endorsements. The 2023 update addressed, for the first time, the use of AI-generated or virtual influencers in endorsements. If a virtual persona is being used to endorse a product and there is a material connection, that connection must be disclosed. This is an area where enforcement is still developing, but the principle is clear.

Social media tagging and endorsements. The Guides now explicitly state that tagging a brand in a social post can constitute an endorsement, even without a formal paid relationship, if there is a material connection. This catches gifting arrangements that some brands had been treating as outside the scope of the rules.

Employee endorsements. If employees are posting about their employer’s products on social media, those posts require disclosure of the employment relationship. This is an area where many brands are not compliant, particularly with organic social advocacy programmes.

For publishers running content-led affiliate strategies, resources like Later’s affiliate marketing guide and Copyblogger’s affiliate case study offer useful context on how to structure affiliate content in a way that is both commercially effective and compliant. The two are not in conflict.

Does Disclosure Hurt Conversion Rates

This is the question I hear most often from publishers and affiliate managers who are nervous about being too transparent. The concern is that if you tell someone you are earning a commission, they will trust the recommendation less and be less likely to click or buy.

My experience, across a lot of performance marketing work, is that this fear is largely unfounded. Readers are not naive. Most people who have been online for more than five minutes understand that content sites make money somehow. A clear, honest disclosure does not damage trust. What damages trust is the feeling of having been deceived, which is exactly what happens when someone discovers a financial relationship that was not disclosed.

There is also a selection effect worth considering. Publishers who are worried that disclosure will hurt their conversions are often the ones whose recommendations are not actually that strong. If your affiliate content is genuinely useful and your recommendations are honest, disclosure does not change the calculus much for your audience. If your content is thinly veiled promotion dressed up as editorial, disclosure might indeed reduce conversions, but that is the market doing its job.

The publishers I have seen build durable affiliate revenue over time are the ones who treat their audience’s trust as the asset, not the commission rate. That orientation makes compliance a natural byproduct of good editorial practice rather than a constraint on it. Copyblogger’s approach to their StudioPress affiliate programme is a reasonable example of how content-led affiliate marketing can work when the editorial integrity is genuinely there.

How to Audit Your Current Affiliate Disclosure Practices

If you are running an affiliate programme or publishing affiliate content and you have not reviewed your disclosure practices since the 2023 updates, a structured audit is worth doing. Here is a practical framework.

For publishers:

• Check every page that contains affiliate links. Does each one have a disclosure that appears before the first affiliate link on the page, not just at the bottom?
• Read your disclosure language as if you had never heard of affiliate marketing. Would a typical reader understand that you earn money if they click and buy?
• If you produce video or social content with affiliate links, does each piece of content have a disclosure that appears at the start, not the end?
• If you use affiliate links in email newsletters, does each email that contains them include a disclosure?

For brands running affiliate programmes:

• Pull a sample of content from your top ten affiliate partners. Does each piece contain adequate disclosure?
• Review your affiliate agreement. Does it include specific disclosure requirements, or just a general compliance clause?
• Do you provide affiliates with example disclosure language, or do you leave them to write their own?
• Is there a process for flagging and addressing non-compliant content, and has it actually been used?

For brands building or reviewing their affiliate infrastructure, resources like Crazy Egg’s affiliate marketing guide and Moz’s affiliate programme overview offer useful reference points for how established brands structure their programmes. Neither is a compliance guide, but both illustrate the kind of programme documentation that supports compliant affiliate relationships.

Common Mistakes Worth Correcting Now

Having reviewed a lot of affiliate content over the years, the same mistakes come up repeatedly. Most of them are not the result of bad intent. They are the result of people setting up affiliate content quickly, without thinking carefully about what the rules actually require.

The footer disclosure. A general “this site contains affiliate links” statement in the site footer is not adequate. It is too easy to miss, too far from the content, and too vague. It needs to be on the page, near the content, in language a reader would understand.

The one-time disclosure on a multi-page site. A disclosure page is not a substitute for in-content disclosures. Having a dedicated “Affiliate Disclosure” page that you link to from the footer does not satisfy the requirement. Each piece of content that contains affiliate links needs its own disclosure.

The vague disclaimer. Language like “some links on this page may be affiliate links” is technically a disclosure but it is not a clear one. A reader who does not already know what an affiliate link is will not understand what it means. Write for the reader, not for the lawyer.

The social media afterthought. Putting #ad at the end of a long caption, after several other hashtags, is not adequate. The disclosure needs to be prominent and early, not something a reader would have to scroll past other content to find.

The email omission. Many publishers who disclose properly on their website forget to disclose in their email newsletters when they include affiliate links. The same rules apply. If you are earning a commission on a link in an email, that email needs a disclosure.

Partnership marketing, done well, is built on transparency. The affiliate channel is no different. If you want to explore how affiliate fits alongside other partnership approaches, the full Partnership Marketing hub covers co-marketing, referral programmes, and channel partnerships in the same commercially grounded way.
