Most SEO advice is about getting a page to rank. Very little explains why a page that already ranks slowly loses traffic while its position barely moves. You haven’t been penalised, and no competitor has overtaken you, yet clicks keep falling month after month.
The reason is something I call intent half-life: the time it takes for a query’s meaning, results layout and demand to drift far enough that your page no longer matches what searchers want. Content doesn’t only age because facts go stale. It also ages because the question behind the query changes.
This post explains the idea, shows how to measure it with free Search Console data, and walks through a worked example.

What Is Intent Half-Life?
A search query is not fixed. Take “best budget laptop”. Two years ago, searchers wanted long spec lists. Today they may want student-specific picks, AI-feature comparisons or video reviews. The words stayed identical while the intent moved underneath them.
Your page was written for the old intent. Google keeps showing it for a while, but the results page gains new features above you, searchers click less, and the page gradually stops satisfying people.
Intent half-life is the point at which your page performs at half the strength it had at its peak. Fast-moving topics such as technology, finance and health may reach it within months. Slower topics, like basic cooking techniques, may take years. Knowing which kind of topic you cover tells you how often to check.
The Three Types of Decay
How’s to Run the Audit
How to Fix Each Type
Position decay: compare your page with the current top three. Look for missing subtopics, outdated facts and weak internal links. Update the existing page rather than publishing a new one, so you keep its history and backlinks.
CTR decay: you can’t remove new results page features, so adapt to them. Rewrite your title to promise something a summary box cannot deliver, such as a tool, template or original data. Add structured data where it applies, and consider adding the format that now dominates, such as a short embedded video.
Demand decay: look at which queries are rising in your query list and build a refreshed page around that phrasing. Merge or redirect the old page only after the new one is established.

FAQ
What is intent half-life in SEO?
It’s the time it takes for a query’s meaning, results layout and demand to drift enough that your page performs at half its peak strength, even if your rankings barely change.
Why is my page losing traffic if my ranking hasn't dropped?
Your position may be stable while the results page changes around you. AI summaries, video carousels and other new features push organic listings down, so fewer people click.
What are the three types of content decay?
Position decay (your ranking falls), CTR decay (your ranking holds but clicks fall) and demand decay (fewer people search for the topic or use that phrasing). Each needs a different fix.
How do I find out which type of decay affects my page?
Export 16 months of Search Console data and compare the latest three months with the same period a year earlier. Then calculate the change in position, the CTR ratio and the impression ratio for each page.
How do I fix CTR decay?
Quarterly is a good rule. Fast-moving topics like tech, finance and health may need more frequent checks, while evergreen topics can be checked less often.
How often should I run this audit?
Quarterly is a good rule. Fast-moving topics like tech, finance and health may need more frequent checks, while evergreen topics can be checked less often.
Conclusion
Rankings are not a trophy you win once. They are a lease that renews every few months, and the terms change as searchers and results pages change.
Running this audit quarterly turns vague traffic drops into specific, fixable diagnoses. Start with your top 10 pages by clicks, calculate the three ratios, and classify each decay type before touching any content. You will often find the page didn’t need a rewrite. It needed the right kind of fix.
