What does CPM means?

CPM is the way we calculate the cost of your campaign. CPM means cost per thousand (the M is Roman Numberal for 1000). For example, $1 CPM indicates a price of $1 per thousand. (To determine the cost of your campaign, divide the quantity by 1000, and multiply by the CPM cost. (ie. if it is $1.00 CPM and you order 10000 visitors, take (10000/1000=10), so an order of 10,000 at $1.00 CPM would be 10 x $1.00= $10.00).
