Content decay is silent. It's one of the biggest reasons established sites lose rankings without knowing why.

Content decay is silent. It's one of the biggest reasons established sites lose rankings without knowing why.

A page that ranked well for two years starts slipping — slowly, then faster. Traffic drops 15%, then 30%, then it's page 3. The page hasn't changed. But the search results around it have. New competitors published better content. The information in the article is now outdated. User expectations for that keyword evolved.

Decay is predictable and preventable.

How to catch it: pull Google Search Console data for pages that were strong 6-12 months ago and compare average position over time. Any page dropping more than 3-5 positions year-over-year is decaying.

Fix it by refreshing: update stats and examples, add sections that address questions the original article missed, improve page structure, and update the publish date once the content genuinely warrants it.

Updating 5 decaying pages often beats publishing 5 new ones.
