Click-through rate (CTR) is the percentage of people who click your ad after it is shown to them. Google Ads defines it as clicks divided by impressions: if 5 people click an ad that was shown 100 times, the CTR is 5%. The same idea applies to Meta ads, emails and even your organic search listings.
Why it matters for your business
CTR is the first sign of whether your message lands. A low CTR usually means the ad is shown to the wrong people, says the wrong thing, or looks like everything else on the page.
It also affects cost. On Google, expected CTR is one of the three parts of Quality Score, and ad quality feeds Ad Rank, which sets your cost per click. On Meta, the system estimates how likely people are to act on your ad, so ads people ignore tend to cost more to deliver.
But CTR is a middle number. An ad that says "free" can earn plenty of clicks from people who will never pay. What matters is whether the right people click.
An example
These are round, illustrative numbers. A furniture shop in Bangalore runs two Google ads for "solid wood dining table".
| Metric | Ad A | Ad B |
|---|---|---|
| Impressions | 10,000 | 10,000 |
| Clicks | 200 | 400 |
| CTR | 2% | 4% |
| Orders | 6 | 4 |
Ad B doubled the CTR with a "Sale: up to 50% off" headline, but the sale covered other items, so many clickers left. Ad A named the wood, the sizes and the delivery area, earned fewer clicks and more orders. Ad A is the better ad.
How to use it
- Compare CTR within the same campaign type and network. Search CTR and Display or feed CTR are very different, so never mix them.
- Write ads that repeat the searcher's words and give a reason to choose you: price range, area served, speed, guarantee you actually offer.
- Add the ad assets that apply, such as sitelinks and calls, which make the ad bigger and more useful.
- On Meta, watch CTR fall over time as a sign the creative is tiring.
- Always read CTR next to conversion rate and cost per result.

Frequently asked questions
What is a good CTR?
There is no single benchmark. Google notes that a good CTR depends on what you are advertising and on which network. The useful comparison is your own ads against each other, over time.
Does a higher CTR lower my costs?
Often, yes, on Google, because expected CTR is part of ad quality, which affects what you pay per click. It only helps the business if those extra clicks come from people likely to buy.
Why is my CTR high but sales low?
The ad is attracting people the offer or page does not satisfy. Check that the ad promises only what the landing page delivers, and look at the search terms or audience the clicks come from.
