FTC Affiliate Disclosure Rules: What You Legally Have to Say (2026)
You've picked your niche, joined your networks — now you're actually putting affiliate links into your content. Before you hit publish, there's one thing that isn't optional: disclosure. This isn't a "best practice" suggestion, it's a legal requirement in the US, and getting it wrong can cost you more than a warning email.
Quick note before we dive in: I'm not a lawyer, and this isn't legal advice — just a plain-English walkthrough of the FTC's public guidance so you know what to look into further. If you want certainty for your specific situation, a quick consult with a lawyer or a read of the FTC's own materials (linked below) is worth it.
Why disclosure exists
The FTC's rule is simple in spirit: if you're recommending a product because you get paid when someone buys it, your audience has a right to know that before they click. It's about protecting consumers from being misled into thinking a recommendation is 100% unbiased when money is actually involved.
This applies everywhere you promote a link — blog posts, YouTube videos, Pinterest pins, TikToks, Instagram captions, emails. Not just your website.
What you actually have to disclose
The core requirements, based on the FTC's published guidance:
- Disclose before the link, not after. A disclosure buried at the bottom of a long post, after every affiliate link has already been clicked, doesn't count. It needs to appear before or right alongside the recommendation itself.
- Use clear, plain language. Phrases like "sponsored," "affiliate link," or "I earn a commission if you buy through this link" are considered clear. Vague terms like "collab" or "thanks for the support" are not considered sufficient on their own.
- Make it easy to notice. It can't be hidden in tiny gray text, buried in a wall of hashtags, or placed somewhere a reader has to hunt for. On video and social platforms, that means it needs to be in the caption or spoken out loud — not just tucked into an "About" page.
- Disclose on every platform you post the link. If you post the same recommendation on your blog, Pinterest, and Instagram, each one needs its own visible disclosure — it doesn't carry over from one platform to another.
What a disclosure actually looks like
You don't need complicated legal language. Something like this is enough for most blog posts:
"This post contains affiliate links. If you click through and make a purchase, I may earn a commission at no extra cost to you."
For social captions, something shorter works:
"#ad" or "Affiliate link — I earn a commission if you buy through this"
The FTC doesn't require exact wording — it requires that an average reader would clearly understand a financial relationship exists.
Common mistakes that get affiliates flagged
- Relying only on Amazon's/network's required disclosure language without adding your own visible one on the actual page or post where the link appears
- Using "#sponsored" or "#ad" buried at the end of a long string of unrelated hashtags on Instagram/TikTok, where it's easy to miss
- Assuming a general disclosure on your "About" or "Disclosure" page is enough — the FTC has said page-specific, in-context disclosure is what matters, not a blanket statement elsewhere on the site
- Forgetting disclosure applies to free products/discounts too — if a company gave you the product for free or at a discount in exchange for a review, that needs disclosing even if there's no affiliate link involved
Where to add this on your blog going forward
A simple, repeatable approach:
- Add one line near the top of every post that contains affiliate links (many bloggers put it directly under the title or in the first paragraph)
- Keep a dedicated "Affiliate Disclosure" page linked in your footer/menu for anyone who wants the full policy
- On social posts, put "#ad" or "affiliate link" directly in the caption, not just the bio
Where to check the actual rules yourself
The FTC publishes plain-language guidance specifically for online endorsements and reviews, including a dedicated FAQ for social media influencers and bloggers. It's worth reading directly rather than relying on secondhand summaries (including this one) if you want to be fully confident in your compliance — rules and enforcement priorities can shift, and this post reflects general guidance as of 2026.
