The Top 5 Best CPM Ad Networks For Your Website:

1. UberCPM

UberCPM is one of the fastest growing CPM ad networks thanks to their instant site approvals and 80% revenue share for publishers. If you have ever had difficulty being accepted by other networks, UberCPM will approve you instantly as long as your site complies with their publisher rules.

UberCPM is an ad exchange platform that puts your inventory on the biggest ad exchanges around, allowing multiple advertisers to bid on your site. For some publishers, they can achieve up to a $10 eCPM thanks to this process, while other sites may receive very few bids. It’s best to allow 4-5 days for your eCPM rates to optimize and for advertisers to review your site.

Publishers enjoy monthly payouts by PayPal, Payoneer and Wire Transfer, real-time stats, 24/7 support and clean ads that are safe to run alongside Google AdSense.

If you are a small to medium sized publisher who wants to supplement their AdSense income or is having difficulty getting their site approved by other networks, UberCPM may be the right choice for you.

2. Adbuff

Adbuff is one of the strongest performing CPM ad networks thanks to their innovative and highly competitive real-time bidding (RTB) platform. Adbuff puts the largest advertisers in the world against one another to bid for inventory on publisher sites. As a result, publishers enjoy the highest CPM rates available in the industry.

Bonus Network: AdRecover

AdRecover is an ad network which exclusively works on recovering your ad blocked inventory, which most publishers are currently not monetizing. Hence this opens a new avenue for publishers to increase their ad revenue by 10-35% by monetizing their ad blocked traffic, which most existing networks (including other networks in this list) cannot monetize since they are blocked by ad blockers.

Through AdRecover, you can measure as well as monetize your ad blocked traffic. Since Ad block users are a sensitive audience, AdRecover maintains a very fine balance between user experience and Monetization, by showing user-friendly ads (that is no rich media, popups, auto-play video, flash ads, etc) and controlling the ad coverage on every page. They also provide website visitors an option to provide feedback about the ads and control their ad experience.
