Affiliate links are how most independent blogs pay for themselves, and the mechanics are simple enough that plenty of publishers never look past the signup form. A reader clicks, buys something, and a commission arrives weeks later. The parts that cause trouble sit on either side of that transaction: what you are required to tell readers before the click, and what you owe once the money lands.
This covers both, plus the practical question of whether to join someone else’s program or run one of your own.
What disclosure actually requires
The Federal Trade Commission sets out its position in the endorsement guides at 16 CFR Part 255, which interpret Section 5 of the FTC Act. Section 255.5 is the one that matters for affiliate links: an unexpected material connection between an endorser and a seller has to be disclosed, and a commission on a sale is exactly that kind of connection.
The standard is clear and conspicuous, which has a specific meaning. The disclosure sits close to the recommendation it relates to, not in a footer, not behind a “read more” toggle, and not buried in a terms page nobody opens. On a review post that means a line near the top, before the first affiliate links, in the same size text as everything around it.
Two details catch people out. The guides apply to both the advertiser and the publisher, so a merchant’s silence does not transfer the obligation away from the blog. And the word affiliate on its own is weak, because plenty of readers do not know what it means. Plain language works better: a short sentence explaining that the site earns a commission if they buy through these links, at no extra cost to them.
None of this hurts conversion in the way people fear. Readers who trust a site buy from it. Readers who discover a hidden commission after the fact stop reading it.
Where affiliate links actually earn
Search intent decides the money, and most blogs get this backwards by spreading affiliate links across every post they publish.
Commissions concentrate in content where the reader is already deciding what to buy: comparisons, alternatives, specific product reviews, and anything with the word best in the query. Informational posts convert poorly no matter how much traffic they pull, which makes them useful for building an audience and close to useless for direct monetization.
Cookie windows shape the rest. A 24-hour window means the reader has to buy almost immediately, while 30, 60, or 90-day windows pay for consideration that takes weeks. A lower commission rate with a long window often beats a higher rate with a short one, and that comparison rarely appears in the promotional material.
Email is the underused channel here, with one condition attached. Promotional sends need the same disclosure, and they need to reach the inbox in the first place, which is a technical problem rather than a copywriting one. A list that goes to spam earns nothing regardless of the offer inside it.
Running a program instead of joining one
Blogs that sell their own product, a course, a template pack, a subscription, sit on the other side of this. Recruiting affiliates means paying only for sales that happen, which is the cheapest acquisition available to a small operation.
Two routes exist. Networks like ShareASale and Awin supply an existing pool of publishers and take a cut of every commission paid, usually 20 to 30 percent plus setup fees. Self-hosted tracking software charges a flat monthly fee and takes nothing from sales, so it wins once volume passes a certain point but does nothing to find partners for you.
Tapfiliate sits in the second category and is a reasonable illustration of the tier: flat pricing from roughly $74 a month, integrations with Stripe, Shopify, and WooCommerce, and a branded affiliate portal, without the enterprise pricing of Impact or PartnerStack. Rewardful and FirstPromoter cover similar ground. The honest read on all of them is that the software is the easy part. Programs fail because nobody recruits or activates the affiliates, not because the tracking was wrong.
The tax side people ignore until January
Affiliate income is business income, and in the US it is taxable whether or not a form arrives. That second half is the part that causes problems, because reporting thresholds moved recently and many publishers assume no form means no obligation.
The IRS guidance on Form 1099-K now reflects the reinstated threshold: payment apps and marketplaces report only when payments exceed $20,000 across more than 200 transactions. Separately, the threshold for Forms 1099-NEC and 1099-MISC rose from $600 to $2,000 for payments made from January 2026, with the first affected forms filed in early 2027. Both changes mean fewer forms, not less tax. A publisher earning $4,000 in commissions through a platform may now receive nothing in the post and still owes exactly what they owed before.
The practical answer is keeping your own records rather than waiting for paperwork to tell you what you earned. Rules differ outside the US, and anyone with meaningful affiliate income should run the specifics past an accountant rather than a blog post.
A checklist worth running
- Put a plain-language disclosure above the first affiliate link on every page that carries one
- Say the site earns a commission rather than relying on the word affiliate alone
- Concentrate affiliate links in comparison and review content, and leave informational posts clean
- Check the cookie window before the commission rate when comparing programs
- Track clicks and conversions yourself rather than trusting each merchant’s dashboard in isolation
- Record every payout as it arrives, since the forms may never come
- Review programs annually, because commission rates get cut quietly and nobody sends a notice
FAQ
Do affiliate links need to be disclosed on every page?
On every page that contains them, yes. The FTC guides require disclosure close to the recommendation, so a single statement on an about page or in a footer does not cover a review published months later. A short line near the top of each post is the workable version.
Do affiliate links hurt SEO?
Not when used normally. Search engines expect commercial links on commercial content and ask that paid or affiliate links carry a rel attribute such as sponsored or nofollow. The ranking problems attributed to affiliate links usually come from thin content built around them rather than the links themselves.
How much do affiliate links earn?
It varies so widely that averages mislead. Rates run from 1 or 2 percent on general retail to 30 percent or more on software with recurring commissions. What matters more is the match between the product and what readers came to the page to solve, since a well-matched offer on modest traffic beats a poor one on heavy traffic.
Is affiliate income taxable if no form arrives?
Yes. In the US all income is reportable whether or not a 1099 is issued, and the recent threshold increases mean many smaller publishers now receive no form at all. Keeping independent records of every payment is the only reliable approach.
