FTC Affiliate Disclosure Rules: What You’re Probably Getting Wrong

FTC endorsement guides require affiliate marketers and the brands that work with them to clearly disclose any material connection, including financial compensation, free products, or any other benefit that could influence a recommendation. The rules apply to influencers, bloggers, review sites, coupon publishers, and anyone else in your affiliate programme who earns a commission for driving action. Getting this wrong is not just a legal exposure issue. It is a trust problem that can quietly erode the credibility of your entire partnership channel.

Most brands running affiliate programmes have a vague awareness that disclosure is required. Far fewer have actually read the FTC’s guidance, audited how their publishers are complying, or built disclosure requirements into their affiliate agreements in any meaningful way. That gap between awareness and action is where the risk lives.

Why This Is a Brand Problem, Not Just a Publisher Problem

There is a tendency in affiliate marketing to treat compliance as the publisher’s responsibility. They are the ones writing the content. They are the ones posting the links. If they fail to disclose, that is on them. This logic is understandable, but it does not reflect how the FTC approaches enforcement, and it does not reflect how consumers experience the problem.

The FTC has made clear that brands can be liable when their affiliates fail to disclose properly, particularly if the brand knew or should have known about the non-compliance. If you are running a programme with hundreds of publishers and doing zero monitoring, you are not insulated from risk. You are accumulating it.

I have seen this play out in agency settings more times than I would like. A brand runs a large affiliate programme, delegates management to a network, and assumes the network is handling compliance. The network assumes the publishers are handling it. The publishers assume it is someone else’s problem. Nobody is actually checking. When I was running agency operations, one of the first things I would do when inheriting a client’s affiliate programme was audit a sample of publisher content. The rate of non-compliant or borderline disclosure was consistently higher than anyone expected.

Affiliate marketing sits within a broader ecosystem of partnership channels, each with its own compliance considerations. If you want to understand how affiliate fits into that wider picture, the Partnership Marketing hub covers the full landscape, from co-marketing to referral programmes to influencer arrangements.

What the FTC Endorsement Guides Actually Say

The FTC’s endorsement guides have been in place in some form since 1980, but the version most relevant to digital marketing was updated in 2009 and significantly revised in 2023. The 2023 update clarified several areas that had become genuinely murky in the age of social media and influencer marketing.

The core principle has not changed. If there is a material connection between an endorser and the brand being endorsed, that connection must be disclosed. A material connection is anything that might affect the weight a consumer gives to a recommendation. This includes payment, commission, free products, discounts, family relationships, employment, and business partnerships.

The 2023 update added specific guidance on several points worth noting:

• Disclosures must be clear and conspicuous, meaning they need to be placed where consumers will actually see them, not in a footer, not in a bio page linked from the post, not in a terms page buried three clicks away.
• On video content, audio disclosure alone is not sufficient if the viewer might miss it. On-screen text is expected.
• The FTC explicitly called out the use of vague or ambiguous hashtags. “#ad” is acceptable. “#sp” or “#collab” are not clear enough for general audiences.
• Brands have a responsibility to monitor their endorsers and take action when non-compliance is identified.

If you want a working definition of affiliate marketing and how it operates before getting into compliance specifics, Later’s affiliate marketing glossary is a reasonable starting point for context.

What “Clear and Conspicuous” Means in Practice

This is where most affiliate programmes fall down. Brands and publishers understand that disclosure is required. The failure is usually in the execution, specifically in treating disclosure as a box to tick rather than a genuine communication to the reader.

Clear and conspicuous means the disclosure must be:

• Placed before the reader encounters the recommendation, not after it.
• In a font size and colour that is actually readable, not greyed out at 9pt.
• Written in language a general audience understands, not legal boilerplate.
• Repeated where necessary. If a post contains multiple affiliate links across different sections, a single disclosure at the top may not be sufficient if readers are likely to land mid-page.

The phrase “this post may contain affiliate links” fails on two counts. “May contain” is deliberately vague when the links clearly do exist. And the word “affiliate” is not universally understood by consumers. Something like “I earn a commission if you buy through links in this post” is cleaner, more honest, and more compliant.

I spent time judging the Effie Awards, which is a process that forces you to look very carefully at how brands claim their marketing works. One thing that exercise sharpened in me was a sensitivity to the gap between what a brand intends to communicate and what a consumer actually receives. Disclosure language is a version of the same problem. What feels adequate to the marketer writing the brief often lands very differently with the person reading it on a phone at 11pm.

How to Build Compliance Into Your Affiliate Programme

There are two levers here: what you require contractually, and what you actually enforce. Both matter. A programme that has strong disclosure language in its affiliate agreement but does zero monitoring is not a compliant programme. It is a programme with paper protection and real-world exposure.

In your affiliate agreement:

Your affiliate terms should include explicit disclosure requirements. Not a vague reference to “complying with applicable law” but specific language about what disclosure must look like, where it must appear, and what language is and is not acceptable. Include examples. Make it easy for publishers to do the right thing without having to interpret legal language.

The agreement should also give you the right to terminate publishers who do not comply, and you should be willing to exercise that right. A large publisher driving significant volume is not worth the compliance exposure if they are consistently cutting corners on disclosure.

In your monitoring practice:

Audit a sample of publisher content on a regular basis. This does not need to be a massive undertaking. Spot-checking your top 20 publishers by revenue each quarter, with a particular focus on new content, will catch most of the significant issues. There are tools that can help with this at scale, and SEMrush’s affiliate marketing tools roundup covers several options worth evaluating.

When you find non-compliance, document it and act on it. Send a clear notice to the publisher with specific examples and a deadline for correction. If they do not correct it, remove them from the programme. The documentation matters both for FTC purposes and for your own internal accountability.

In your publisher onboarding:

Most affiliate programmes treat onboarding as a formality. Fill in the form, agree to the terms, get your tracking link. The compliance conversation happens once, in legal language, and is never revisited. A better approach is to build a short onboarding resource that explains disclosure requirements in plain language, with examples of compliant and non-compliant content. It takes a few hours to create and removes the most common excuse publishers give when they get it wrong, which is that they did not know exactly what was required.

The Influencer Overlap and Why It Complicates Things

The line between affiliate marketing and influencer marketing has blurred considerably. Many influencer arrangements now include affiliate commission structures alongside flat fees or gifting. This creates a situation where the same piece of content might technically fall under both influencer marketing guidelines and affiliate disclosure requirements.

The FTC does not draw a meaningful distinction between the two. If there is a material connection, disclose it. The channel, the platform, and the commercial structure are secondary to that core principle.

Where it gets complicated in practice is with micro-influencers who are enrolled in affiliate programmes but may not think of themselves as marketers. They have a following, they share a link, they earn a small commission. They may genuinely not know that this arrangement requires disclosure. The brand’s responsibility here is to be explicit in its programme materials and to monitor accordingly.

Some affiliate programmes, like Later’s affiliate programme and Moz’s affiliate programme, publish clear guidance for their affiliates on how to promote responsibly. That is the right approach. It reduces compliance risk and it signals to publishers that the brand takes this seriously.

Does Disclosure Hurt Performance?

This is the question that sits behind a lot of the resistance to proper disclosure. The implicit assumption is that if you tell someone you are earning a commission, they will discount your recommendation and not convert. The evidence for this assumption is much weaker than most affiliate marketers believe.

Consumer attitudes toward affiliate marketing have shifted. Audiences who regularly read blogs, watch YouTube, or follow creators on social platforms are largely aware that the content they consume is often monetised. A clear, honest disclosure does not destroy trust. In many cases, it builds it, because it signals that the publisher is not trying to hide anything.

What does hurt performance is the kind of content that exists solely to generate affiliate revenue, with no genuine editorial value. Disclosure does not fix that. But for publishers who are genuinely recommending products they use and believe in, disclosure is not a conversion killer. It is just honesty.

I have managed enough performance marketing budgets across enough industries to be sceptical of the idea that consumers are easily fooled and that fooling them is a sustainable strategy. At lastminute.com, where I ran paid search campaigns that generated six figures of revenue from relatively straightforward setups, the lesson was always the same: match the message to the reality, and the numbers follow. Trying to obscure the commercial nature of what you are doing is a short-term play with long-term costs.

Structuring Affiliate Relationships With Compliance in Mind

The way you structure your affiliate partnerships upstream has a direct effect on how easy compliance is downstream. If you are working with a large network and have no direct relationship with individual publishers, your ability to monitor and enforce is limited. If you have a managed programme with direct publisher relationships, you have much more control.

This is one argument for a hybrid approach: using a network for volume and reach, but maintaining a curated tier of direct relationships with your most significant publishers. That top tier gets more attention, more support, and more scrutiny. It is also where most of your revenue is likely concentrated.

Partnership structures more broadly benefit from this kind of tiered thinking. The Forrester perspective on channel partner value is worth reading for context on how different partner types require different management approaches. The same logic applies to affiliate relationships.

Co-marketing arrangements, which often sit adjacent to affiliate programmes, bring their own disclosure considerations. If you are jointly promoting a partner’s product in exchange for reciprocal promotion, that relationship may need to be disclosed depending on the nature of the arrangement. Mailchimp’s co-marketing resource is a useful primer on how these arrangements typically work.

The broader point is that compliance is easier to build in at the design stage than to retrofit after the fact. When I was growing an agency from 20 to over 100 people, one of the things I learned is that process debt accumulates the same way technical debt does. Every time you skip a compliance step because it feels like friction, you are borrowing against future risk. The cost of sorting it out later is always higher than the cost of doing it right the first time.
