Clickthrough rate (CTR)

Clickthrough rate (CTR) is a way of measuring the success of an online advertising campaign. The clickthrough rate of an advertisement is defined as the number of clicks on an ad divided by the number of times the ad is shown (impressions), expressed as a percentage. For example, if a banner ad is delivered 100 times (100 impressions) and receives one click, then the clickthrough rate for the advertisement would be 1%.
