Clickthrough rate or CTR is a way of measuring the success of an online advertising campaign. A CTR is obtained by dividing the "number of users who clicked on an ad" on a web page by the "number of times the ad was delivered" (impressions). For example, if a banner ad was delivered 100 times (impressions delivered) and one person clicked on it (clicks recorded), then the resulting CTR would be 1 percent.
