CPM vs RPM — what's the difference?

CPM (Cost Per Mille) is the amount advertisers pay per 1,000 ad impressions. It's the gross figure before the platform takes its cut.

RPM (Revenue Per Mille) is what you as a creator actually receive per 1,000 views — after YouTube retains its share, which is typically around 45%. So if your CPM is $8, your RPM is roughly $4.40.
