Before the next rewrite is queued, run this checklist on the nominated URL and log the cause so the brief starts from evidence, not a hunch. ## Frequently Asked Questions ### How is content decay different from a penalty or a logging error? Decay is a slow multi-month slide, such as about 5% a month for eight months. A large overnight drop is a different problem, and a reported drop can also be a Search Console processing or logging error—check Google’s Data Anomalies page before you treat the chart as lost traffic. ### How long a window should I use before I diagnose decay? Do not diagnose an evergreen page from fewer than 14 complete days; a practical default is 28 complete days versus the preceding 28. Google also tells site owners to open Performance to the last 16 months so a yearly seasonal dip is not mistaken for a new problem. ### What does it mean when clicks fall but impressions stay flat? Declining clicks with stable impressions usually means a CTR problem: the title or snippet is no longer earning the click, or a richer result nearby is. It is not, by itself, proof that the page needs a rewrite. ### Should I rewrite a page that slipped from position 2 to 4? Not automatically. Google notes that a small slip inside the top results, such as position 2 to 4, can cut traffic without a large impression change, and advises against radical changes if the page is already performing well. ### Can I trust 2025 year-over-year impression drops? No. Search Console impression history from 2025 is unreliable for year-over-year demand reads because a logging error inflated impressions from May 2025 and was not backfilled. Clicks were never affected. ### Can a page still rank and still look decayed because of AI answers? Yes. On queries with an AI Overview, the top organic result loses around 58% of its clicks, so rank can hold while clicks fall. Separately, URLs cited by AI assistants are 25.7% fresher than organic results on average, so citation loss can run ahead of ranking loss. ## Sources - [https://thestacc.com/blog/content-decay-fix/](https://thestacc.com/blog/content-decay-fix/) - [https://www.blogseo.io/blog/content-decay-before-traffic-drops](https://www.blogseo.io/blog/content-decay-before-traffic-drops) - [https://www.amicited.com/seo-playbook/process/checklists/content-refresh/](https://www.amicited.com/seo-playbook/process/checklists/content-refresh/) - [https://www.clicklaboratory.com/content-analytics/how-to-measure-content-decay/](https://www.clicklaboratory.com/content-analytics/how-to-measure-content-decay/) - [https://developers.google.com/search/docs/monitor-debug/debugging-search-traffic-drops](https://developers.google.com/search/docs/monitor-debug/debugging-search-traffic-drops) - [https://searchengineland.com/content-decay-types-fix-482486](https://searchengineland.com/content-decay-types-fix-482486) - [https://www.siteguru.co/seo-academy/content-decay](https://www.siteguru.co/seo-academy/content-decay) - [https://blog.hubspot.com/marketing/historical-blog-seo-conversion-optimization](https://blog.hubspot.com/marketing/historical-blog-seo-conversion-optimization) - [https://ahrefs.com/blog/content-decay/](https://ahrefs.com/blog/content-decay/)
