CTR Calculator
Click-through rate (CTR) measures what percentage of people who saw your ad or content actually clicked on it — a core metric for gauging relevance and engagement.
The formula
CTR = (clicks ÷ impressions) × 100
Worked example
Your ad gets 150 clicks from 10,000 impressions:
CTR = (150 ÷ 10,000) × 100 = 1.5%
Frequently asked questions
What is a good CTR?
It depends heavily on the channel and format — search ads often see CTRs in the low single digits, while display and social ads are typically well under 1%. Compare your CTR against similar campaigns on the same platform rather than a single universal benchmark.
Why is my CTR important?
CTR is a signal of how relevant or compelling your ad or content is to the audience seeing it. Many ad platforms also factor CTR into ranking and cost, so a higher CTR can lower your cost per click.
Does a high CTR always mean a good campaign?
Not necessarily — a high CTR with a low conversion rate can mean the ad attracts clicks but isn't reaching people likely to buy. It's worth looking at CTR alongside conversion rate and cost per acquisition.
