Put next month’s decay audit on the same day as your KPI report and close every priority URL with a classified action before anyone opens a rewrite. ## Frequently Asked Questions ### What is content decay? Content decay is a gradual loss of organic traffic and rankings over months or years, not a sudden penalty or algorithm hit. Ahrefs notes that it is slow, and that competitor improvement is the most common cause because displacement happens gradually. ### How often should a content decay audit run? Monthly. Click Laboratory finds that annual-only reviews typically surface decay about six months after it started, so a monthly workflow is meant to catch the slip earlier—without turning every flag into an immediate rewrite. ### Which Search Console ranges should the audit compare? Compare the last three months with the same three months a year earlier, and open a 16-month Performance chart so the drop can be checked against the same pattern last year. That three-month year-over-year window fits inside Search Console’s 16-month history. ### When is a content refresh the wrong fix? When the signature is not ranking decay. MarTech finds that only clicks down, impressions down, and a worse position are reliably fixed by a refresh. Flat impressions with falling clicks more often mean a title, snippet, or rich-result change, and Google recommends avoiding radical edits if the page is still performing. ### Can 2025 impression drops be trusted in a year-over-year read? Treat 2025 impression comparisons as noisy. MarTech reports that Google removed the num=100 parameter in September 2025 and that a logging error inflated impressions from May 2025. Clicks were not affected, so confirm the live SERP before calling an impression drop demand decay. ### Does a page-one ranking mean the URL is fine for AI answers? No. Ahrefs notes a page can still rank on page one and be absent from ChatGPT or Google AI Overviews. Across 16.975 million cited URLs, AI assistants cited pages that were 25.7% fresher than organic SERP URLs—1,064 days old versus 1,432—so citation loss belongs on its own line of the audit. ## Sources - [https://ahrefs.com/blog/content-decay/](https://ahrefs.com/blog/content-decay/) - [https://www.clicklaboratory.com/content-analytics/content-decay-monitoring-workflow/](https://www.clicklaboratory.com/content-analytics/content-decay-monitoring-workflow/) - [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://martech.org/before-you-refresh-that-page-run-this-test/](https://martech.org/before-you-refresh-that-page-run-this-test/) - [https://ahrefs.com/blog/do-ai-assistants-prefer-to-cite-fresh-content/](https://ahrefs.com/blog/do-ai-assistants-prefer-to-cite-fresh-content/) - [https://republishai.com/content-optimization/content-refresh/](https://republishai.com/content-optimization/content-refresh/)
