What Is Content Decay — and How Do You Fix It?

You published a blog post two years ago. It ranked well for a while, brought in steady traffic, and then quietly started slipping. Fewer impressions. Fewer clicks. Lower position. Nothing dramatic — just a slow decline that's easy to miss until you look at the data.

That's content decay. And it's more common than most people realise.

What is content decay?

Content decay is the gradual loss of organic search performance over time. A page that once ranked in positions 3–5 for a valuable keyword slowly drifts to position 8, then 12, then off the first page entirely.

It doesn't happen overnight, which is why it's easy to overlook. But across a site with hundreds of pages, the cumulative effect can be significant — a steady erosion of traffic that's hard to reverse if left too long.

Why does it happen?

New competition

Other sites publish better, more comprehensive content on the same topic. Google updates its rankings to reflect the best current answer — and your page gets pushed down.

Outdated information

Statistics, tools, prices, and best practices change. A guide that was accurate two years ago may now contain outdated advice. Users bounce quickly, which signals to Google that the page isn't satisfying search intent.

Shifting search intent

What people mean when they search a phrase evolves over time. A keyword that once brought informational searchers may now attract buyers — and your informational page no longer matches what they're looking for.

Algorithm updates

Google's ranking criteria change regularly. Pages that were well-optimised for older signals may lose ground as new factors become more important.

How to spot it in Google Search Console

1. Open Google Search Console and go to Performance → Pages
2. Set the date range to the last 12 months and compare to the previous 12 months
3. Sort by impressions and look for pages where both clicks and average position are declining
4. Pages with position above 12 and CTR below 2% that are also trending downward are your primary decay candidates

How to fix content decay

Fixing a decaying page is almost always faster and more effective than writing a new page from scratch. The page already has ranking history and backlinks — you're rehabilitating an asset, not building a new one.

Step 1: Understand why it's decaying

Before you start writing, Google the target keyword and study the top 3–5 results. What do they cover? How long are they? What do they do that your page doesn't?

Step 2: Update outdated information

Go through the page and replace every statistic, tool recommendation, or piece of advice that may have changed. If you're referencing prices, check they're current. If you're recommending software, check it still exists and is still the best option.

Step 3: Fill content gaps

Add sections covering angles or questions your page doesn't currently address. If the top-ranking pages have a section you don't, that's a gap worth filling.

Step 4: Sharpen the title and introduction

Your title tag should clearly communicate what the page is about and why it's worth reading. The introduction should confirm the search intent immediately — the reader should know within the first two sentences that they've found what they were looking for.

Step 5: Add internal links

Go to other relevant pages on your site and add links pointing to the refreshed page. This sends a signal to Google that the page is connected to the rest of your content and deserves re-evaluation.

How long does it take to see results?

After a thorough refresh, most pages start recovering within 4–8 weeks. Google needs time to re-crawl the page, re-evaluate it, and update its rankings. Be patient and don't make further changes for at least a month — you need a clean signal.
