What is CTR (click-through rate)?
Clicks divided by impressions. A search result shown a thousand times and clicked fifty is running a five percent CTR; the same math applies to an ad, an email link or a button. The number is the simplest measure of whether a thing shown was a thing wanted. In organic search it has a particular meaning: Google Search Console reports the CTR of every page and every query, which turns the title and meta description of each page into something you can test and improve without touching the ranking.
Position drives it. The first organic result takes a large share of clicks, the share falls steeply down the page, and anything below the first screen on a phone gets very little. A CTR is only meaningful next to the position it was earned at.
Why it matters
Why CTR matters
Because ranking is not the finish line. Two pages at position three for the same query can see very different traffic depending on how their listings read, and the one with the better title has doubled its result for free. Across a site, the pages with high impressions and low CTR for their position are the cheapest traffic gains available: the ranking is already won and only the pitch is losing.
CTR is also a diagnosis. A page with a high ranking and a low click rate is often ranking for a query it does not really answer, or being outshone by a featured snippet, an AI Overview or a competitor's richer result. The number tells you to look.
In practice
How CTR works in practice
- 01
Open the Search Console performance report, filter to a page or a query, and compare CTR against position. Pages at positions one to five with click rates well below what those positions normally earn are the targets. Rewrite the title to say plainly what the page offers and why it is worth the click, write a meta description that answers the query's intent in a sentence, and add structured data that earns rich results (ratings, FAQs, images), because a listing that takes up more space takes more clicks.

Test and wait. Change one thing per page, note the date, and read the CTR for the same query over the following weeks against the same position. Seasonality and ranking shifts muddy the picture, so compare like with like. In paid campaigns the same loop runs faster: variants side by side, the platform splits impressions, the winner is clear in days.
Watch out
What people get wrong about CTR
Judging it without position. A two percent CTR is a disaster at position one and a triumph at position nine. The other mistake is writing clickbait titles to lift it: the clicks come, the visitors leave immediately, and the page's real performance, measured in what people do after the click, gets worse. A title should promise exactly what the page delivers.
Assuming CTR is a direct ranking factor. Google has been evasive on the point and the evidence is mixed; what is certain is that a better listing earns more traffic at the same rank, which is reason enough.
