Click-through rate
—
Click-through rate (CTR) is the share of people who clicked after seeing your ad, email, or search listing. It's a core signal of how compelling your creative and targeting are. Enter clicks and impressions to get your CTR as a percentage.
How to calculate ctr
Formula
CTR = (Clicks ÷ Impressions) × 100
Divide clicks by impressions and multiply by 100. A higher CTR usually means your message and audience are well matched, and on paid platforms it often lowers your costs because engagement improves ad quality scores. Read CTR alongside conversion rate — a high CTR that doesn't convert can signal a mismatch between the ad and the landing page.
Example
An ad got 450 clicks from 100,000 impressions.
CTR = (450 ÷ 100,000) × 100 = 0.45%.
