Cost per Thousand


Cost per Thousand

In online advertising, the measurement of cost paid by an advertiser per 1,000 impressions of its advertisement. One impression is one view of the advertisement by a website viewer. Many websites, especially those with high traffic, charge advertisers on a per 1,000 impression basis. It differs from a cost per click scheme, in that the viewer does not have to click on the ad in order for the advertiser to be charged.
