What is content decay?
Content decay is the slow loss of rankings and traffic on a page that used to perform well. It usually happens over months, not overnight, which makes it easy to miss: the page still gets some visits, so nobody notices it sent three times as many a year earlier.
Almost every site has decaying pages. Content ages, competitors publish better pages, and what searchers want from a query changes. The good news is that decaying pages are often the cheapest wins available, because they already have history, links, and proven relevance.
Common causes
- Outdated information. Prices, product names, screenshots, and years in titles ("best grinders 2023") go stale.
- Better competing pages. Someone published a more complete, more current answer.
- Search intent shifted. A query that used to want a guide now wants a product list, or the other way round. See search intent.
- Results page changes. A new featured snippet, AI answer, or video block pushes organic results down.
- Internal competition. A newer post on your own site targets the same query. See keyword cannibalization.
- Lost links, or broken links on the page itself.
How to find decaying pages
In Search Console's Performance report:
- Set a date comparison, such as the last 3 months against the same 3 months a year earlier. Comparing the same months avoids mistaking seasonality for decay.
- Open the Pages tab and sort by the difference in clicks.
- For each page with a large drop, check the Queries tab for that page to see which queries lost clicks and whether average position fell.
A drop in position means the page is losing rankings. Steady position with falling clicks suggests the results page changed or demand fell. The fix is different for each.
What to do about it
| Situation | Action |
|---|---|
| Still the right topic, facts outdated | Update and expand it, keep the URL |
| Competitors cover more | Add the missing sections and answer follow-up questions |
| Two of your pages compete | Merge into the stronger one and 301 the other |
| Topic no longer relevant to your site | Redirect to a close match, or remove it |
| Demand simply fell | Leave it, and spend the effort elsewhere |
When you update, make real changes: new information, better examples, corrected details. Changing the date without changing the content does not help and misleads readers. The refreshing old posts guide covers the process, and pruning thin content covers the pages not worth saving.
Common questions
How often should I check for content decay?
A quarterly review of your top pages works for most sites. Busy publishers with many time-sensitive pages may want to check monthly.
Does updating the published date help rankings?
Not by itself. Google looks at the content, and a new date with no real changes gives it nothing new. Update the date when you have made meaningful changes.
Is content decay the same as a penalty?
No. It is a gradual loss caused by age and competition. A sudden sitewide drop is more likely a core update, a technical problem, or a manual action.
