In this episode of #asksovrn we answer “What’s the Difference Between CPM and RPM?”
Ashley and Maggie, two Sovrn Publisher Advocates, discuss the difference between two metrics to determine ad revenue; CPM (cost per thousand impressions) and RPM (revenue per thousand impressions).
While RPM is the metric used almost exclusively by Google Adsense, CPM is the metric used by a majority of online advertisers and publishers to determine ad zone cost and revenue. The two are not the same!
If you use Google Adsense in addition to another ad partner that uses CPM as its metric, you will notice that Google’s RPM is typically always higher than the ad partner’s CPM. This episode teaches you why Google’s RPM metric is different than CPM and how to make sure you are comparing apples to apples when measuring your ad zones and page revenues.
