Enter clicks and impressions to get your click-through rate.
How it works
Click-through rate (CTR) is the share of people who clicked after seeing your ad, link, or search result. Enter the number of clicks and the number of impressions, and the calculator divides one by the other.
Formula: CTR = (Clicks / Impressions) x 100.

Frequently asked questions
What is click-through rate?
CTR is the percentage of impressions that resulted in a click. It measures how compelling your ad, email, or search listing is at getting people to act on what they saw.
How do I calculate CTR?
Divide clicks by impressions and multiply by 100. For example, 250 clicks from 10,000 impressions is 250 / 10,000 x 100 = 2.5% CTR.
What is a good CTR?
It depends heavily on the channel and placement: search ads and email often see higher CTRs than display ads, and branded keywords beat generic ones. Compare against your own past performance and similar placements rather than a universal number.
What counts as an impression?
An impression is one display of your ad, link, or listing, whether or not it was clicked. Definitions differ slightly by platform (for example, "viewable" impressions), so use the same source for clicks and impressions.
