How do you keep affiliate links from dying quietly and costing you commissions?

Why affiliate links break differently

An affiliate link is rarely a single hop. A typical chain runs from your own cloaked or shortened link, through the network's tracking domain, and finally to the merchant's landing page with attribution parameters attached. Each hop can fail on its own. The final page may load perfectly while the tracking hop has quietly stopped crediting you: the program ended, your publisher ID was deactivated, the merchant moved to a different network, or the deep link parameter format changed and the old one is now ignored.

Standard link checkers report the status of the final destination. A 200 at the end of the chain tells you nothing about whether your identifier survived the trip. Merchants also retire product pages constantly. Some redirect discontinued items to the homepage, which converts poorly, and some to a category page, which converts a little better. In both cases the link looks healthy, the click still counts, and the commission simply stops arriving.

Checks that actually catch the failures

Follow the complete redirect chain and record every hop, including the final URL with all of its query parameters intact. Verify that your affiliate identifier, or the network's click ID pattern, appears on the hop where it should. Flag any chain where the final URL lost its parameters, where the number of hops changed since the last run, or where the final URL is the merchant's homepage rather than the product or landing page you originally linked to.

Go one step further and watch the destination content. Keep a baseline per link that includes the page title and a hash of the main content, then compare on each run. A changed product title, out of stock messaging, or a missing price block are all signals worth a human look. For affiliate links specifically, treat a 200 landing on a generic page as a failure condition, even if you would tolerate the same behavior from an ordinary outbound link.

Handling networks, cloaking, and rate limits

Tracking domains often rate limit or block automated requests, and some record every checker hit as a click, which can pollute your statistics or violate program terms. Read the rules for each program before pointing a monitor at it. Check at a low frequency, send a descriptive user agent, and split the work: verify the first hop you control (your own cloaked redirect) as often as you like, and hit the network hop less often, with confirmation by a manual click-through on your highest earning links.

Cloaking links through your own domain, using a path like /go/product-name, gives you a single place to update a destination when it breaks, plus your own click logs independent of the network. Before you cloak anything, confirm that each program permits redirected or masked links, because some programs restrict or forbid them and can close a publisher account over it. Pair that with an inventory that maps each cloaked slug to the merchant, the program, and every page that uses it. That inventory is what turns a broken link report into a short, prioritized task list instead of a site-wide search. Related: Why Broken Links Quietly Hurt Your SEO

Building a maintenance routine

A workable cadence looks like this. Weekly, review any links flagged for lost parameters, homepage redirects, or a changed hop count. Monthly, reconcile your inventory against the network's list of active programs, because programs get paused or closed without every publisher being told. Quarterly, click through the links on your top earning pages by hand and confirm that attribution appears in the network dashboard, since a manual test is the only check that proves the full path end to end.

Prioritize by revenue rather than by count. One dead link on the page that earns most of your commissions matters more than dozens across archived posts nobody reads. When a merchant ends a program, replace the link with an alternative merchant or a plain non-affiliate link instead of leaving a redirect that goes nowhere, and note the date so you can revisit it if the program reopens.
