Terminology Definition: Click-Through Rate (CTR)

What does Click-Through Rate (CTR) mean?

Click-Through Rate, commonly referred to as CTR, is a metric that measures the number of clicks advertisers receive on their ads per number of impressions. It's calculated by dividing the number of clicks an ad receives by the number of times the ad is shown (impressions), then multiplying by 100 to get a percentage. A high CTR is a good indication that users find your ads helpful and relevant.
