A page that brought in steady enquiries last year now gets a fraction of the clicks, and nobody touched it. That slow slide is content decay, and it usually means the search results moved on while the page stayed put. This guide shows how to confirm decay in Google Search Console, work out what is causing it, and choose between updating, merging, redirecting or removing each page. It also covers how decay now shows up in AI answers, and ends with a 90-day plan a content team can run. If the basics are still new to you, our primer on what SEO is is a good place to start. Content decay is the gradual decline in a page’s organic traffic and rankings over time, usually across months rather than days. Ahrefs describes a typical page life as early traction, growth, a peak, a plateau where rankings quietly slip, and then decline. Most teams put effort into the first three stages and almost none into the last two. Naming it matters because the response differs from an emergency. A decayed page is already indexed and may already carry links, so refreshing it often costs less than publishing something new. The catch is that not every decline is decay, and treating the wrong problem wastes weeks. One more wrinkle: a page can lose ground in Google rankings and drop out of AI-generated answers independently of each other. “Still ranking” no longer means “still being seen.” Ahrefs calls this the most common cause and the hardest to spot, because displacement happens one position at a time. A rival adds original data, a clearer structure or a few good links, and your page slips from third to fifth with no alert. Working out who overtook you is the most useful piece of competitor analysis you can do on a declining page. Google runs freshness systems built to show newer content for queries where recency is expected. Think pricing, tool comparisons, regulations and “best of” lists. A definition of a stable concept needs this far less, which is why a five-year-old explainer can still hold a top spot while a two-year-old tool comparison cannot. The same keyword can start meaning something else, or the format Google prefers can change. Search intent is not fixed. In one Ahrefs example, forum threads grew from 34% to 60% of page one for a how-to query within a year, while beginner guides fell from 27% to 22%. A guide written for the older results is now answering a question fewer searchers are asking. Two articles aimed at the same query split links and attention, and Google may swap which one it shows. The newer post often overtakes the older one, so the older page looks like it is decaying when it is really being cannibalised. Rankings can hold while clicks fall. An AI Overview, a featured snippet or a new rich result can absorb clicks without moving your position. It looks like decay but needs a different fix. Ahrefs suggests checking whether the decline began after a change. If it did, restoring or repairing the earlier version beats a refresh. Redesigns, template changes and well-meant rewrites are the usual culprits. Google’s Performance report opens on the last three months by default, and the date filter lets you compare any two periods. That comparison is the whole method. Work through it in this order: Compare the last three months with the same three months a year earlier. Year over year removes seasonality, which fools more audits than any other mistake. Open the Pages view and sort by the change in clicks. Look at the biggest losers, not the biggest pages. For each loser, read impressions and CTR together, using the table below. Open that page’s queries and note which lost position and which simply stopped being searched. Export the data. Search Console keeps only about 16 months of history, so a monthly export builds the baseline you will want later. If the page has dropped out of Google’s index, you have a technical fault, not decay. Check the Page indexing report, and if URLs are missing, our guide to why Google isn’t indexing your pages covers the usual causes. A redesign that slowed the template is the other early suspect, so check Core Web Vitals for that page type before rewriting a single paragraph. Ahrefs suggests flagging pages that lost more than 20% of traffic year over year in a quarterly audit. Treat that as a starting filter. A page with 40 monthly visits can swing by half on noise alone, while a 15% slide on your best lead-generating page deserves attention today. Not every decaying page deserves rescue. Ask three questions: how much did it earn at its peak, does it still support something you sell, and can you realistically win the query now? Pages that score well on all three go first. Pages that score poorly on all three are candidates for removal. Picture a Coimbatore interior design studio with a 2023 “cost per square foot” guide that still sits third. The right move is not a rewrite. Update the price ranges, add the sections that newer competitors cover, and leave the parts Google already likes. On redirects, relevance decides everything. Ahrefs notes that sending a blog post to the homepage may not consolidate link signals, because the two pages are too different. Pick the closest topical match. If none exists, a clean removal beats a lazy redirect. Add before you rewrite. If the page still holds a position for its main query, a full rewrite can throw away the passages doing the work. Rewrite only when intent has changed enough that the page now answers a different question. Read the current results for your main query. Note the dominant format, the subtopics every top page covers and anything new since you published. Fill real topic gaps. Add the sections a searcher would expect, backed by specifics rather than padding. Our piece on content depth explains how to tell depth from length. Replace stale facts and dead links. Swap every statistic you can for a newer, traceable one, and fix or drop broken outbound links. Rework the title and meta description. Write them for the query as it is searched today. Google rewrites many of them anyway, so see how to optimize title tags and meta descriptions so yours survive. Rebuild internal links. Point links from your strongest, most visited pages to the refreshed one with descriptive anchors. Internal linking is how the authority of pages that still perform reaches the one that slipped. Change the date only when the change is real. Google’s guidance on dates says to update the visible date after a significant update, and warns against freshening a page without adding significant information. Ask for a recrawl, then tell people. Request indexing through URL Inspection, and share the updated page with your email list and social channels. Google states that there are no additional requirements to appear in AI Overviews or AI Mode, and that a page must be indexed and eligible to show with a snippet. Its AI features documentation also says traffic from these features is counted within overall search traffic in Search Console. In practice, a click drop caused by an AI answer and a click drop caused by lost rankings look identical on the chart. Separate them by position: a stable position with falling CTR points at the results page, and a falling position points at the content. Beyond Google, check the assistants directly. Each quarter, ask your ten most valuable questions in ChatGPT, Perplexity and Google, and note who gets cited. Our guide to AI SEO, GEO and AEO covers what to change when a competitor keeps appearing and you do not. Changing dates without changing content. Google advises against it, and readers notice. Refreshing everything at once. Spread effort by past traffic and business value, or the work never finishes. Rewriting a page that still ranks. You lose the passages Google already rewards. Merging or deleting without a relevant redirect. The links pointing at the old URL go nowhere. Treating every dip as decay. Seasonality, a new SERP feature or a technical fault each need a different response. Judging results too early. Google has to recrawl and reassess the page. Compare against the same period a year earlier, not last week. Search Console and Google Analytics 4 are free and enough to find decay. Rank trackers and crawlers such as Ahrefs, Semrush or Screaming Frog speed things up on larger sites and carry subscription costs. The bigger expense is writer and subject expert time, which scales with the number of pages you refresh, not with the tools. Judge each refresh against its baseline on five things: clicks and impressions for the page, average position for its main query, CTR, leads or conversions from the page in GA4, and whether it now appears in AI answers for your key questions. Content decay is the gradual loss of organic traffic and rankings on a page that used to perform. It usually builds over months because competitors improve, search intent shifts or the information ages. It is separate from a sudden drop caused by an algorithm update or a technical fault. Compare Search Console clicks and impressions for the last three months against the same period a year earlier. A steady fall in both on an indexed page, with no technical fault or confirmed update behind it, points to decay. Quarterly suits most sites, using year over year comparisons. Pages tied to pricing, tools or fast-moving topics may need checks more often, and your top lead pages deserve an annual review even without a decline. Not on its own. Google advises updating the visible date only after a significant update, and warns against freshening a page without adding real information. Change the content first, then the date. Only when a page has little traffic, few links and no business value. If it has backlinks, redirect it to a closely related page. If you are unsure, noindex it first, because that can be reversed and deletion cannot. It depends on how often Google recrawls the page and how competitive the query is. Allow a few weeks before judging, and compare against the same period a year earlier rather than the week before the update. Yes, and the two can move separately. A page can hold its Google ranking and still go uncited in AI answers. Google says the same technical requirements apply to AI Overviews and AI Mode, so keep the page indexed, accurate and clearly structured. Search Console and GA4 are free. Paid tools such as Ahrefs or Semrush save time on larger sites. The main cost is writer and expert time per page, so it scales with how many pages you refresh. Yes. Ahrefs found that most pages in Google’s top 10 are more than three years old, so age is not the issue. Accuracy, links and fit with current intent are.What Content Decay Is, and How It Differs From a Normal Traffic Drop
