What is content decay?
Content decay is the gradual drop in a page's traffic or rankings over time, usually because the surrounding competition or expected format has moved on while the page stayed the same.
Decay rarely means the page became factually wrong. More often, the market around it changed: competitors published clearer or more current pages, expectations for depth or format shifted, and the original page simply stopped being the best available answer, even though nothing on it is technically incorrect.
For AI visibility specifically, decayed pages tend to lose citations before they lose search rankings. An AI answer engine has no reason to keep citing a source once a clearer or more current version of the same answer exists somewhere else, and citation choices get made fresh on every query rather than carried forward from a page's past performance.
The fix isn't always a full rewrite. Checking whether the page still states its answer clearly near the top, and still compares favourably to what else now exists on the same question, is often enough to diagnose what actually decayed and what didn't.
