RPM (Revenue Per Mille) is the estimated revenue you earn per 1,000 pageviews. It varies by niche and ad network.

Google AdSense is free to join with no minimum traffic. RPMs are lower but it is perfect for new bloggers starting out.

Mediavine requires a minimum of 50,000 sessions per month. It offers significantly higher RPMs due to premium ad placements and optimization.

AdThrive requires a minimum of 100,000 monthly pageviews. It is a premium network with the highest RPMs, offering white-glove service for established bloggers.

Actual earnings vary based on audience location, seasonality, ad placement, and content quality. These estimates use industry-average RPMs.
