Example
A guide loses nonbrand clicks across two comparable 28-day windows while its former queries shift to more current implementation pages.
Glossary · content decay
The loss may appear in visibility, qualified engagement or conversion contribution. A short fluctuation is not enough; compare appropriate windows and investigate query, SERP, page and technical context.
Why it matters
Undetected decline compounds; premature refreshing creates churn and destroys a clean baseline.
In practice
A guide loses nonbrand clicks across two comparable 28-day windows while its former queries shift to more current implementation pages.
Segment page/query clicks and impressions, compare suitable periods, check seasonality, deployments, index state and SERP composition.
Investigate update, consolidation, redirect or no change; attach a baseline and outcome window to any approved proposal.
