How to calculate click-through rate
Click-through rate is the share of impressions that turn into clicks.
- CTR = clicks / impressions x 100
- Impressions per click = impressions / clicks
- Clicks at a target = impressions x target CTR / 100
- Extra clicks = clicks at target – clicks now
Worked example
An ad is shown 50,000 times and gets 750 clicks. The CTR is 750 / 50,000 x 100 = 1.50%. That is one click for every 66.7 impressions, or 15.0 clicks per 1,000 impressions. To reach a target CTR of 2%, the ad would need 50,000 x 2% = 1,000 clicks, which is 250 more than now.
CTR is a signal of how well a message fits an audience, but it is not the goal on its own. A very high CTR on a poor landing page just buys cheap visits that do not convert. Look at CTR together with conversion rate and cost per click. To raise it, test the headline, the image and the offer, and keep the audience and the placement the same while you test so that you know what moved the result.
Assumptions & limits
- The clicks and impressions must cover the same ad, the same period and the same channel.
- Different channels count clicks differently. Search ads, social posts and emails usually show very different CTRs, so compare like with like.
- Impressions that happen without a chance to be seen can lower the CTR on some platforms.
- CTR does not measure sales or quality. Check conversion and cost as well.
- The target CTR is your own goal and not a benchmark.
Frequently asked questions
How do I calculate CTR?
Divide clicks by impressions and multiply by 100. 750 clicks on 50,000 impressions is a 1.5% CTR.
What is a good CTR?
It varies a lot by channel and audience. Compare with your own past results and with others in your own niche.
Does a higher CTR lower my cost?
On many ad platforms a stronger CTR can improve quality scores and lower the cost per click, but this depends on the platform.
What affects CTR?
The headline, the image, the offer, the audience and the placement all play a part.
Can CTR be above 100%?
No. Clicks cannot exceed impressions in the same report.
Is CTR the same as conversion rate?
No. CTR counts clicks on the ad. Conversion rate counts how many visitors then buy or sign up.
