How to use the CTR calculator

Enter clicks and impressions to calculate click-through rate. Add a target CTR to estimate how many clicks the same number of impressions would require.

CTR formula

CTR = Clicks / Impressions x 100.

Example: 1,250 clicks from 100,000 impressions

1,250 clicks divided by 100,000 impressions equals a 1.25% CTR.

How to interpret CTR

CTR only describes how often an impression becomes a click. A high CTR can still be unprofitable if clicks are expensive or do not convert, so evaluate CTR alongside CPC, conversion rate, CPA and ROAS.

Frequently asked questions

What does CTR mean?

Click-through rate is the percentage of impressions that resulted in clicks.

In normal impression-click reporting it should not.

Should I compare CTR across channels?

Use caution because placements, formats and user behavior differ by channel.
