Cost-per-thousand-impressions (CPM)
Advertisers running CPM ads set their desired price per 1000 ads served and pay each time their ad appears.
As a publisher, you'll earn revenue each time a CPM ad is served to your app and viewed by a user. CPM ads compete against cost-per-click (CPC) ads in our ad auction. We'll display whichever ad is expected to earn more revenue for you.
