Almost every page peaks, then slides. It ranks, pulls traffic for a few months, and then, without anything obviously breaking, the clicks start to thin out. Nobody notices, because nothing failed. The page still loads, still ranks, still looks fine. That slow, silent decline is content decay, and across a whole site it quietly leaks more traffic than most broken pages ever will.

What content decay actually is

Content decay is a gradual loss of organic performance on a page that used to perform well. It is not a penalty, not a de-indexing, and not a technical error. The page simply becomes a little less competitive every month until, a few quarters later, it is a shadow of what it was. Because the drop is spread over time, it almost never triggers an alert. You find it by looking, or you do not find it at all.

Why pages decay

Decay is rarely one thing. Usually it is a few of these stacking up at once:

The information got stale. Prices, dates, screenshots, or facts drifted out of date, and Google (and readers) can tell.
The SERP changed shape. AI Overviews, a new featured snippet, more ads, or a video carousel pushed your result further down the page even though your ranking did not move.
Competitors refreshed. Someone published something newer and more complete, and your once-best page is now the second-best answer.
Intent drifted. What people mean when they search that query slowly changed, and your page answers the old version of the question.
Internal links faded. You stopped linking to the page from new content, so it lost the internal support that kept it strong.

How to spot decay in Google Search Console

You do not need a paid tool to find decay — the data is free in Google Search Console (GSC). The trick is to compare two equal periods instead of looking at one:

Open Search results and set the date filter to Compare → the last 3 months against the previous 3 months.
Switch to the Pages tab and sort by the click difference so the biggest losers rise to the top.
For each declining page, add the Average position and CTR metrics and look at how they moved.
Separate real decay from SERP shifts (see the callout below) before you decide anything.

The zero-click trap. If a page lost clicks but held its ranking and impressions, it is often not decaying — an AI Overview or featured snippet is answering the query directly in the results, so fewer people click through. That is a positioning problem, not a content-quality problem, and rewriting the page will not fix it. Real decay looks like clicks and average position sliding together.

Refresh, consolidate, or retire?

Once you have a shortlist of genuinely declining pages, each one gets one of three decisions:

Refresh when the page still targets a valuable query and just needs updating — new facts, a tighter answer up top, fresh examples, current dates.
Consolidate when two or three thin pages compete for the same query. Merge them into one strong page and redirect the rest.
Retire when the topic is dead or off-strategy. Redirect it to the closest relevant page so its remaining authority is not wasted.

A simple rule: if the query still matters and the page is fixable in an hour or two, refresh it. If you are maintaining five weak pages that should be one, consolidate. Everything else, let go.

How often should you check?

For most sites, a monthly pass is the right cadence — often enough to catch decline while a page still has momentum to recover, rare enough that it does not become a full-time chore. The catch is that monthly discipline is exactly the thing that slips first when you are busy, which is why decay so often goes unnoticed until a page has already lost most of its traffic.

Where automation helps — and where it does not

Detection is mechanical: comparing periods, ranking losers, and filtering out the zero-click cases is exactly the kind of work software should do for you every month without being asked. The judgement — is this query still worth owning, does this refresh match our brand, should we merge or kill — stays human. The honest version of automation is one that surfaces the right pages and drafts a starting point, then waits for a person to approve it. It should never quietly rewrite and publish on its own.

That is exactly what Tedrix does: it connects to your Search Console, runs the decay check for you every month, and drafts one on-brand refresh per page for you to approve. Run a free audit of your own site to see which pages are quietly slipping right now.
