What is Content decay?
Content decay describes a page losing rankings and clicks without anything happening to the page itself. That is the decisive difference from a drop after a rebuild: here the cause sits outside the page. A competitor publishes something better, Google reshapes the result page, the query itself shifts, or the figure in the text stops being true. The page stands still while its frame of reference moves.
The sequence is typical, which is what makes it detectable. Average position slides first while impressions hold. Impressions fall next, because the page drops out of the positions where visibility exists at all. Only then do the clicks go. Watch clicks alone and you notice last. Search Console shows both earlier stages if you put position and impressions for a single URL side by side.
The remedy is selection rather than frequency. The pages affected almost always carry a built-in expiry: prices, deadlines, legal positions, market figures, tool comparisons. Timeless explainers age far more slowly and need no update simply for being old. A refresh works when it changes the substance, correcting a wrong figure or adding a missing section. A new date without new substance changes nothing, and Google names exactly that in its own quality checklist as a marker of content built for search engines rather than people.
Why does Content decay matter?
Content decay is the one loss of visibility you can see months in advance, because it shows up in position first and in traffic last. Watch position and you repair a page while it still has visibility. Wait for traffic and you repair a page nobody sees any more, which takes considerably more than a correction.
Content decay in practice
- 01A pricing page quotes last year's figures; position slides from 4 to 11 over eight weeks while impressions hold almost steady.
- 02A guide to a funding scheme loses visibility because the application deadline in the text has passed and competitors quote the new one.
- 03A tool comparison slips after two of the vendors covered change their pricing model and the table still lists the old one.
