Content decay
What is content decay?
Content decay is the gradual decline in a page’s search rankings and organic traffic over months or years, after a period of steady performance. It isn’t a penalty; it is what happens when a page stays the same while searcher needs, competitors and search results move on.
Common causes include outdated information, newer and better competing pages, a change in search intent (for example, searchers now want a video or a tool), new SERP features such as AI Overviews taking clicks, loss of backlinks, and your own newer pages competing with the old one.
Why content decay matters for SEO
Decay is slow, so it is easy to miss until a lot of traffic has gone. Catching it early is usually cheaper than writing new content: an established page with links and history often recovers quickly with a well-targeted update.
Separate decay from seasonality. A page about tax returns that drops after the filing deadline is seasonal, not decaying. Compare the same period year on year.
How to find content decay
- In Search Console, compare clicks for each page over the last 3-6 months with the same period a year earlier.
- Sort by the biggest absolute loss in clicks, not percentage, so you focus on what matters.
- For each declining page, check whether rankings, impressions or CTR fell. Lower CTR at the same position suggests a SERP change; lower impressions suggest lost rankings or demand.
- Look at what now ranks above you and what has changed.
- Decide whether to refresh, merge or retire the page.
Content decay FAQ
How do I stop content decay?
You can’t stop it entirely, but regular reviews and updates of your most valuable pages slow it down and often reverse it.
Is a traffic drop always content decay?
No. It may be seasonality, a Google update, a tracking problem or a technical issue such as a page being deindexed. Check those before rewriting.

A content refresh is a substantial update of an existing page to make it current, accurate and more useful, so it regains or improves rankings.
Content freshness is how recent and up to date a page is. Google ranks fresher content higher for queries where recency matters.
A content audit is a review of every page on a site, with data, to decide which to keep, update, merge, redirect or remove.
Evergreen content is content that stays relevant and useful for a long time, such as how-to guides and explainers, rather than news.
Keyword seasonality is the regular rise and fall of searches for a keyword through the year, such as "sunscreen" in summer or "advent calendar" in autumn.
