What does CTR specifically measure?

Click-Through Rate (CTR) specifically measures the effectiveness of an advertisement or email campaign in terms of user engagement, defined by the number of clicks received relative to the number of times the ad or email was displayed, known as impressions. This metric is crucial for assessing how well an advertisement captures the audience's attention and drives them to take action, such as visiting a website or engaging with content.

In this context, a high CTR indicates that the ad is effective in prompting users to click through, while a low CTR may suggest that the ad is not resonating with its intended audience or that the message needs improvement. By focusing on the relationship between clicks and impressions, marketers can gauge the performance of their campaigns and make informed decisions to optimize their digital marketing strategies.
