Paste any page URL and this finds every affiliate link on it, then flags the ones that are leaking money or risking your rankings: Amazon links with no tag, links missing rel="sponsored", a missing or badly-placed disclosure, and over-reliance on a single merchant. Broken-link checking is a different job — for that, use the link checker; this is about whether your affiliate links are set up to actually pay you.
The mistake that costs the most
The single most expensive affiliate error is also the easiest to miss: an Amazon link that lost its ?tag= somewhere between drafting and publishing — a copy-paste, a plugin update, a migrated post. The link still works, the visitor still buys, and you earn nothing. A page can look perfect and quietly leak commission on every click. This tool checks for exactly that first, then the compliance and diversification issues that decide whether your affiliate setup is built to last.
Frequently asked questions
What does this find that a normal link checker doesn't?
A normal link checker only tells you whether a link is broken (404). This audits links for affiliate-specific problems that quietly cost you money: Amazon links with no ?tag= (so the click earns you nothing), affiliate links missing rel="sponsored" (which Google asks for), pages with affiliate links but no disclosure (an FTC issue), and heavy reliance on a single merchant. No other free tool checks these.
How does it detect affiliate links?
It fetches the page and inspects every outbound link, matching against known affiliate networks (Amazon, ShareASale, CJ/Rakuten, Impact, Awin, ClickBank, Partnerize, Skimlinks and more), affiliate tracking parameters, and cloaked redirect paths like /go/ or /recommends/. It reads only the public HTML and never stores the pages you check.
What's a 'naked' or 'untagged' Amazon link?
An Amazon URL with no ?tag= parameter. Amazon uses that tag to credit your Associates account — without it, the visitor still buys, but you earn zero commission. These are the single most expensive mistake on affiliate pages, and they're easy to miss, which is why this tool flags them first.
Does missing rel="sponsored" hurt my SEO?
It can. Since 2019 Google asks that paid and affiliate links be marked rel="sponsored" (or at least nofollow). Missing it doesn't guarantee a penalty, but it removes a clear signal and can draw link-scheme scrutiny — and it's trivial to fix, usually site-wide from your affiliate plugin.
Can it tell me which links actually earn?
No — and nothing that only reads the HTML can. Whether a link earns depends on clicks, source pages, and merchant conversion, which live in your traffic data. This tool fixes the setup; measuring which links earn is what Clickolytics is for.
