Cost Per Mille

What is CPM?

In the CPM or Cost Per Mille model, advertisers pay publishers/app developers a fixed amount for every 1000 impressions on the ad shown on the publisher’s app.

CPM is an important metric for advertisers as it indicates the amount they pay for the ad space. On the other hand, it defines the value of the publishers’ ad space and helps in calculating the revenue per 1000 impressions.
The formula for CPM is as follows:

CPM = Cost / Impressions X 1000
