Click-Through Rate (CTR)

Click-Through Rate (CTR) is a key metric in online advertising that measures the effectiveness of an ad campaign. 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 express it as a percentage.

CTR = (Total Clicks / Total Impressions) * 100

A higher CTR generally indicates that your ad is relevant and compelling to your target audience. It's often used in conjunction with other metrics like Cost Per Click (CPC) to evaluate overall campaign performance.
