Question 1

What is a good CPM?

Accepted Answer

Average CPMs vary widely: Display ads $1-5, YouTube $2-15, newsletters $20-50, podcasts $15-50. Finance and B2B content commands the highest CPMs ($15-50+) while entertainment and general content earns $1-8.

Question 2

What's the difference between CPM and RPM?

Accepted Answer

CPM (Cost Per Mille) is what advertisers pay. RPM (Revenue Per Mille) is what publishers earn — always lower than CPM because platforms take a cut (YouTube keeps ~45%, Google Display keeps ~32%). RPM = CPM × (1 - platform fee).

Question 3

How do I increase my CPM?

Accepted Answer

Target high-value niches (finance, B2B, SaaS), focus on US/UK/AU audiences (3-5x higher CPMs than global), increase video length (YouTube pays more for mid-roll ads), and optimize for session time. Q4 CPMs are typically 50-100% higher than Q1.
