点击率（英语：Click through rate，缩写CTR），又称点进率，一种衡量网页热门程度的指标。

点进率 = 广告被点击次数 / 广告被显示次数

举例来说，若广告显示次数为100次，在这一百次中这广告显示中被网友点击了五次，那该广告的CTR就等于5/100 = 5%。

Click-through rate (CTR) is the ratio of users who click on a specific link to the number of total users who view a page, email, or advertisement. It is commonly used to measure the success of an online advertising campaign for a particular website as well as the effectiveness of email campaigns.
