Click-Through Rate

Click-Through Rate (CTR) is a measure used to evaluate the effectiveness of online advertising and content. It is calculated by dividing the number of clicks an ad or link receives by the number of times it is shown (impressions), then multiplying by 100 to get a percentage. For example, if an ad is shown 100 times and receives 5 clicks, the CTR would be 5%. A higher CTR indicates that a higher percentage of viewers found the ad engaging or relevant enough to click on, which can be a sign of successful marketing.
