Adbuff
Adbuff is the ultimate AdSense Alternative ad network due to their ability to outperform AdSense for many publishers. Because Adbuff is a Real Time Bidding (RTB) platform, AdSense is competing directly with other advertisers to monetize your site through Adbuff. As a result publishers earn some of the highest page RPMs available in the industry. Their ads are also fully compliant to run along-side AdSense, so you can even double your page RPM by running AdSense and Adbuff together.
Adbuff is an AdSense Alternative ad network that has strict approval guidelines for publishers and advertisers. They are currently accepting publishers who have English sites with a majority of the traffic coming from USA, Canada, Australia and the UK. Publisher sites require at least 2,000 unique visitors per day. Approval times can take between 5 – 7 days and every approved site will receive a $25 welcome bonus for signing up.
For premium publishers who are looking for the best AdSense Alternative ad network, Adbuff is the first ad network you should look at.
