How CTR is Calculated
Click-through rate measures how often people who see your ad actually click on it.
The formula is simple: divide your total clicks by total impressions, then multiply by 100 to express it as a percentage.
For example, if your ad received 50 clicks from 2,000 impressions, your CTR would be 2.5%.
Impressions count every time your ad is displayed, regardless of whether the viewer engaged with it.
CTR is typically used across search ads, display banners, social media campaigns, and email marketing.
Most platforms calculate this automatically, but understanding the math helps you spot reporting issues and compare performance across channels that may define impressions differently.
