Cannabis affiliate SEO answers to two rulebooks at once. The FTC's Endorsement Guides require a clear disclosure on every page that earns you a commission, and most mainstream networks — Amazon Associates included — refuse CBD and THC products outright. The work is disclosing properly and choosing programs that will actually have you.
Two rulebooks, not one
The first rulebook is federal. The FTC's Endorsement Guides, updated in 2023, apply to anyone paid to recommend a product. Cash, commission, or free product all count as a material connection, and that connection has to be disclosed. The second rulebook is private: affiliate networks and the merchants behind them write their own terms, and cannabis sits on most exclusion lists. Neither rulebook cares that your content is honest. Disclosure and program eligibility are separate hurdles, and you clear them separately.
Disclose the way the FTC means it
The FTC standard is clear and conspicuous. In practice, that means the disclosure sits where a reader sees it before clicking: top of the review, not the footer, not a linked policy page. Plain words beat legalese. "We earn a commission if you buy through links on this page" does the job. On social posts, #ad at the start of a caption works; buried in a hashtag pile, it does not. Accessibility counts too. If the disclosure only exists inside an image, part of your audience never got it.
Expect mainstream networks to say no
Amazon Associates is the clearest case: Amazon bars CBD product listings, so there is nothing compliant to link to. Google Ads prohibits promoting THC products, which closes the paid-traffic arbitrage play. Most large affiliate networks treat cannabis as a restricted category. What remains is narrower but real. In-house programs run by seed banks, smoke shops, grow-equipment brands, and CBD merchants fill the gap, and each writes its own terms on claims, creatives, and traffic sources. Read them before you build pages around them.
A disclosure that fails, and one that passes
Fails: a "some links on this site may be affiliate links" sentence sitting on a separate disclosures page, linked from the footer. A disclosure the reader has to hunt for is no disclosure at all.
Passes: "Heads up — we earn a commission if you buy through links in this review. It doesn't change the price you pay." Placed directly under the H1 and repeated near the comparison table on long pages. Specific, visible, and in the reader's path before any affiliate link.
The merchant's claims become your claims
The FTC requires substantiation for objective product claims, and repeating a claim in your review makes it yours. If a CBD merchant says a tincture treats anxiety and your comparison page repeats it, you have made a disease claim — the same category of claim that shows up in joint FDA and FTC warning letters to CBD companies. Strip treat, cure, and prevent language from your copy no matter who wrote it first. Google adds a second layer: health-adjacent affiliate pages get YMYL scrutiny, so unsupported claims can cost rankings on top of everything else.
- Disclose material connections clearly, before the links, on every page that earns a commission.
- Amazon Associates and most large networks exclude CBD and THC; plan around in-house programs.
- Repeating a merchant's disease claim makes it your claim.
- #ad only works on social when it is the first thing a reader sees.
Frequently asked questions
Do affiliate links on a cannabis blog need a disclosure on every page?
Yes. The FTC's Endorsement Guides treat a commission as a material connection, and the disclosure has to appear on each page where the links live: clear, close to the links, and readable before the click. A site-wide disclosures page linked in the footer does not meet the standard.
Can I promote CBD through Amazon Associates?
No. Amazon prohibits CBD product listings, so there is no compliant catalog to send readers to. CBD affiliates work mostly through merchants' in-house programs, and each program sets its own terms on claims, creatives, and traffic sources.
Am I on the hook if a merchant's product claim is false?
You can be. Publishing or repeating a claim puts your name on it, and the FTC expects substantiation from whoever makes the claim. Rewrite merchant copy in your own words and cut any treat, cure, or prevent language before the page goes live.
