Most lost Amazon affiliate commission doesn't disappear in the payout — it's lost at the link. A copied URL that keeps Amazon's internal ref= parameters instead of your tag=, a shortened link that violates the operating agreement, or a tag typed wrong once in a CMS and pasted a hundred times. Every one of those links earns Amazon the sale and you nothing. This guide covers the correct format, how to test a link before publishing, and the free tools that build and check your links for you.
A working Associates link has three parts: the domain, the product path, and your tracking ID. The cleanest version looks like this:
https://www.amazon.com/dp/B0EXAMPLE123?tag=yourstore-20
Two things matter here. First, keep /dp/ASIN — the stable product path — and drop everything after it except your tag. Amazon appends ref= junk to every URL it shows you; if you paste the URL straight from the address bar, your tag will be buried behind those parameters and often won't register. Second, the tag suffix is marketplace-specific: -20 for the US, -21 for the UK, and different suffixes for other stores. Reuse a US tag on a UK link and Amazon has no idea who referred the sale. The Link Tools build this correctly per marketplace so you never have to remember the suffix.
Run a quick audit of your existing posts before you write another one. Look for these failure patterns:
AmzLossref= parameters — they usually mean the tag was pasted mid-URL where it gets ignored./dp/ASIN product page — these often slip through.The Link Tools validate the tag against your account and flag each of these patterns, so you can fix a hundred links in a few minutes instead of clicking through them one by one.
A link can look perfect and still fail. The reliable test is to open it in a private window and check for your tag in the final URL bar before Amazon's redirects settle — if your tag survives, the link is sound. For an extra check, click the link and then visit Associates Central: a qualifying click from a tagged link appears in your traffic report within a couple of hours. If the click doesn't show up, the link was broken before it ever went live. Make that one-click check a habit before hitting publish, and it will catch the vast majority of silent failures.
While you're fixing links, decide once what your link attributes look like. Amazon affiliate links are outbound to a third party, so most sites mark them rel="nofollow" (or rel="sponsored") to stay safe — this is covered in full detail in our nofollow and sponsored guide. Whatever you choose, apply it consistently, and keep the target="_blank" and rel attributes straight in your CMS so you're not editing hundreds of posts later.
A clean tag-based URL built directly from the product's Amazon page — for example /dp/ASIN with ?tag=your-account-20 (US) or your-21 (UK). No cloaking, no redirect service: Amazon reads the tag on the standard URL and credits the referral. Test the link before publishing to confirm the tag survived copy-paste.
No. Amazon's operating agreement explicitly prohibits cloaking and link-shortening services like Bitly for Associates links. You must use direct tag-based links or the official SiteStripe format. If you want a prettier link, build a product page on your own site and link that page with your tag, not a redirect.
Take the product URL, replace the 'ref=' parameters with '?tag=YOURTRACKINGID-20' (US) or '-21' (UK), and drop everything before '/dp/ASIN'. The tag must be your exact Associates tracking ID. The AmzLoss Link Tools generate this correctly per marketplace so you never mistype it.
