CTR – click-through rate

Short for click-through rate, the ratio of the number of times a user clicks on an online advertisement per number of viewers who view the Web site that has the advertisement on it. For example, if one out of 100 people who visit a specific Web site click on an advertisement and are taken to the advertiser’s site, then the CTR of that advertisement is 1/100, or 1%.
