Understand Cost per CPM

CPM stands for Cost per Thousand Impressions. It is the price you will pay for your Internet advertising, based on a dollar amount you pay for every one thousand times your banner ad is displayed on a publisher’s site. If the publisher charges $4.00 CPM, you will be paying $.04 every time a banner ad is displayed on its website regardless of click through rate (CTR).
