Explanation of Click-Through Rate (CTR)

Click-through rate (CTR) is a metric that measures the percentage of users who click on an advertisement or link compared to the total number of impressions. It is calculated by dividing the number of clicks by the number of impressions and multiplying by 100. CTR is an important indicator of ad effectiveness and user engagement. A high CTR suggests that the ad or link is relevant and compelling to the audience, while a low CTR may indicate the need for improvements. Marketers use CTR to evaluate the performance of their campaigns and optimize their strategies to increase engagement and conversions.
