Ad Click-Through Rate

Ad Click-Through Rate (CTR) is a metric that measures how often people click on an online ad after seeing it. It's calculated by dividing the number of clicks an ad receives by the number of times the ad is shown (impressions), then expressing that as a percentage. For example, if an ad is shown 100 times and 5 people click on it, the CTR is 5%. A higher CTR generally indicates that the ad is relevant and engaging to the audience, helping advertisers understand the effectiveness of their campaigns.
