What metric indicates the percentage of users who saw your ad and then clicked on it?
The metric that indicates the percentage of users who saw your ad and then clicked on it is the Click-Through Rate (CTR). It's calculated by dividing the number of clicks an ad receives by the number of times the ad is shown (impressions) and expressing the result as a percentage. A higher CTR suggests that the ad is relevant and engaging to the target audience. For example, if an ad is shown 1,000 times and receives 20 clicks, the CTR is 2%.
