CPM
In plain English
What does CPM mean?
Cost per mille: the price of one thousand ad impressions, the standard way display and push traffic is sold.
CPM prices traffic by impressions rather than clicks or actions, so the affiliate carries all the risk: a $2 CPM is only cheap if the creative earns clicks. Native, push and display networks quote CPM; pop traffic is usually sold on CPV or CPM per thousand pops.
