In one sentence: Click-through rate, usually shortened to CTR, is the percentage of people who click a link after seeing it, worked out by dividing clicks by impressions, and it is the standard way to judge whether a search listing, an ad, or an email is earning attention.
Click-through rate is one division problem. Clicks on top, impressions on the bottom, expressed as a percentage.
The word doing the quiet work there is impression. An impression is counted when your listing is displayed to someone. It does not mean they read it, or looked at it, or scrolled far enough down the page to reach it. It means a search engine, an ad platform, or an inbox put it in front of them.
As a worked example, say your gutter cleaning page was shown 1,000 times in search results last month and 40 people clicked through. That is a click-through rate of 4 percent.
Whether 4 percent is good is not a question anyone can answer for you, and you should be suspicious of anybody who tries. The number moves with where you ranked, what was typed, and how much of the answer was already sitting on the results page before your listing came into view. Your own trend, on the same page, for the same kind of search, is the only benchmark worth keeping.
Ranking and being chosen are two separate jobs. You can hold a decent position all month and still watch the listings above and below you take the clicks, because their wording said the thing the searcher needed to read.
For a local business that thing is usually plain. The town. The exact service, not the category it belongs to. Whether you are open right now. Whether a person answers the phone. A listing written like a brochure loses to a listing written like an answer.
Click-through rate is also not a dial you can turn directly. You change what the listing says, and you change what the page behind it delivers, then you watch the rate respond over a few weeks. If your positions have held steady and the clicks are drifting down, the wording of the listing and the substance of the page behind it are the two places to look, and sorting that out is the ordinary daily work of SEO.
One honest caveat. A growing share of searches end without anyone clicking anything, because the answer is presented on the results page itself. When that is happening in your category, your rate can slide while nothing on your site has gotten worse. Read a falling rate as a reason to go and look, not as a verdict.
Organic search, paid search, and email all report something called click-through rate, and the three are not comparable. Same arithmetic, different denominators, different consequences.
In organic search the impressions cost you nothing, so a poor rate costs you attention and nothing else. In paid search you bid to be shown and you pay when somebody clicks, so a poor rate means you won placements nobody acted on, and it also feeds the quality score the platform uses when it decides what your clicks cost. In email, the bottom of the fraction is sometimes everyone the message was sent to and sometimes only the people who opened it, which is why two reports on one campaign can disagree and both be right.
So before you hold your rate up against anything, check what is sitting on the bottom of that fraction and over what window it was counted. That one habit heads off most of the arguments people have about this number.
No. A listing that promises something the page does not deliver will pull clicks from people who leave within seconds, and on paid search you pay for every one of them. Read the rate next to what those visitors do after they arrive.
Nobody outside the search engines can settle that argument, and there is no setting that lets you feed the number back in. Treat it as a diagnostic rather than a lever. A listing nobody clicks earns you nothing either way, which is reason enough to fix how it reads.
