Content Decay Audit
Every site has performance leaders silently shedding traffic. This is the diagnostic framework to find them, classify the decay type, and ship the winning refresh.
Why decay is the unglamorous SEO win
Decay repair restores a page that already earned page 1 and is quietly losing the position back to a competitor or an AI Overview. The Median decaying page is shedding 18-35% of its prior clicks per quarter. Left untreated, the decline accelerates because lower clicks reduce engagement signals.
The asymmetric upside: the same page already has the backlinks, the indexation, and the internal link weight. The refresh ships in a few hours and the position recovers in 1-3 crawl cycles.
The Four Types of Content Decay
Topic Misalignment
The query's top SERP results have shifted to answer a different variant of the question. Your page is now an intent mismatch.
Competitor Displacement
A competitor shipped a better page and Google moved them above you. You need to match-and-exceed on freshness or depth.
Rich Result Erosion
The page lost an FAQ block or sitelinks. Position is stable, but CTR collapsed. Root cause is often schema or framework drift.
AI Overview Compression
An AI Overview now answers the query directly. The path is to become the citation source, not rewrite the snippet.
