Amazon Affiliate Link Checker
Paste your links and find the ones quietly earning nothing — missing tags, wrong regional suffix, or pointing at a search page instead of a product.
The silent failure mode of affiliate links
An untagged affiliate link looks completely normal. The reader clicks, the product page loads, the purchase goes through — and you earn nothing. There is no error, no warning in your dashboard, just a slow drift downward in earnings that is easy to blame on seasonality.
The regional mismatch is even more common. Most affiliates start with a US tag, then link to amazon.co.uk or amazon.de for their European readers using the same tag. Those clicks track nothing, because each Associates programme only recognises tags it issued. This checker flags both cases in one pass, per store.
Fix it once with country routing
The permanent fix is to stop publishing one store's link to a global audience. A Smart Link holds a destination per country — each with its own correctly suffixed tag — and sends every reader to the store that pays.
