Content decay is the slow decline in rankings, impressions and clicks that most pages experience after their peak. An article that brought 2,000 visits a month two years ago might bring 400 today without anything obviously breaking. Managing it is an ongoing part of SEO content writing and often delivers faster gains than publishing new pages.
Why content decays
- Competitors publish better pages that are newer, deeper or better formatted.
- Information goes out of date: prices, statistics, screenshots, laws and product names change.
- Search intent shifts and Google starts favouring a different type of page.
- SERP changes: AI Overviews, videos and other features push organic results down.
- Lost backlinks or internal links weaken the page.
- Cannibalisation by newer articles on your own site.
How to find decaying content
- In Google Search Console, open Performance, set the date range to compare the last 3 months with the same period a year earlier.
- Switch to the Pages tab and sort by click difference.
- Note pages with large drops in clicks and impressions.
- Check whether average position or click-through rate caused the drop.
Analytics tools that track organic landing pages over time give the same picture.
Refresh, merge or prune?
Refresh
For pages that still target a valuable keyword: update facts and examples, add sections competitors cover, improve the intro and headings, add new images, strengthen internal links and update the published date only when changes are substantial.
Merge
When several weak articles cover similar ground, combine them into one strong page and 301 redirect the others. This also fixes keyword cannibalisation.
Prune
Remove pages with no traffic, no links and no future value. Return a 410 or redirect to a relevant page. Pruning improves the average quality of your site.
Content pruning vs content decay
Decay is the problem; pruning is one possible response. Most decaying pages deserve a refresh rather than deletion.
Build a refresh routine
- Review the top 20 traffic pages every quarter.
- Review the whole site once a year.
- Keep a changelog of updates to measure impact.
- Prioritise pages linked to revenue.
Frequently asked questions
Does changing the date help rankings?
Not by itself. Google looks for meaningful updates, not new timestamps.
How soon after a refresh will traffic recover?
Often within two to six weeks of recrawling, if the update was substantial.
