How to actually read these numbers
The first mistake I made years ago was chasing the biggest CPM number I could find. CPM is what an advertiser pays per thousand impressions — but you don’t bank impressions, you bank pageviews. That’s why the calculator shows effective RPM: revenue per thousand pageviews, after the messy real-world stuff like fill rate and how many ad slots you run. When you compare networks, compare RPM. A network with a lower headline CPM but better fill can quietly out-earn a flashier one.
If you want the deeper breakdown with real examples, I wrote a full comparison of Adsterra vs Monetag vs AdSense CPMs, and a roundup of the best AdSense alternatives for low-traffic sites.
Display vs multi-format — which fits you
Display networks (AdSense, Ezoic, Media.net) and premium managed networks (Mediavine, Raptive) keep the reading experience clean, which is why they pay best on Tier-1 content traffic where advertisers compete hard for attention. Multi-format networks (Adsterra, Monetag, PropellerAds) add popunder, push and social-bar demand. Those formats are more aggressive, but they’re often the only way to earn real money from Tier-2/Tier-3 or entertainment traffic that display networks barely value.
Not sure whether ads are even your best money method? Run the monetization advisor, or browse every network and platform in the networks directory. If you’re still weighing revenue models, this breakdown of ads vs affiliate vs CPA vs products is worth ten minutes.
Can you run two networks at once?
Yes — and past a certain point you probably should. The reliable play is one clean display network for reader trust plus one multi-format network to monetize what display leaves on the table. There’s one hard rule: never run popunder or onclick ads on the same pages as AdSense. It breaks AdSense policy and the bans are usually permanent. Keep them on separate pages, or keep AdSense off the pages where you run aggressive formats.
