How This Calculator Works
Enter the number of clicks and the number of impressions. The calculator divides one by the other to give the click-through rate as a percentage, and shows the share of views that did not click.
The Formula
Part as a Percentage of a Whole
Part is the portion, Whole is the total it belongs to
Worked Example
An ad with 1,200 clicks from 50,000 impressions has a click-through rate of 2.4%. The other 97.6% of views did not click — the audience a sharper headline or offer is trying to win.
Key Insight
Click-through rate measures appeal, not outcome. A high CTR shows the headline draws attention, but only the conversion rate that follows shows whether those clicks were worth winning.
Frequently Asked Questions
What is click-through rate?
Click-through rate, or CTR, is the share of impressions that resulted in a click — clicks divided by impressions, as a percentage.
What is a good click-through rate?
It varies enormously by channel, placement, and audience. Compare against your own past performance and similar campaigns rather than a universal number.
What counts as an impression?
An impression is one display of the ad or link. Be consistent — count an impression each time it is shown, however the platform defines it.
Does a high CTR mean success?
Not by itself. CTR measures whether something attracts a click. Whether those clicks convert into a sale or sign-up is a separate, often more important question.
How can I improve CTR?
Sharper headlines, a clear and relevant offer, better targeting, and stronger creative all tend to lift the click-through rate.
