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.
