We have advertising accounts at Adsense and at Lifestreetmedia for our Pirates game and other websites. We noticed the RPM (revenue per 1000 impressions) varies between the two. We also noticed the two ad networks have APIs.

We have built a self hosted ad server that rotates ads between these two networks and others based on RPM. It will auto install and auto update like Wordpress.

Eventually we'd like to build an ad network like Mopub.com's marketplace that rotates ads into user's sites if it can meet or beat the RPM.

We have an adserver serving live ads for our Pirates game (https://greenrobot.com/pirates). If you'd like access to the demo, please get in touch with me at andy@greenrobot.com

About us: Julie and I are siblings. I am a Android developer for a startup, and Julie is a car mechanic and a clown for children's birthday parties. She is also a graphic designer and advertising consultant: she has designed graphics for apps and sites we have developed, and created ads for affiliate products we were promoting. I am overseeing development of the adserver. I have hired a Laravel PHP expert and I also have contributed to the development myself. Julie plans on handling publisher and advertiser support once development has been completed. One impressive thing about us is the Pirates game on Facebook at it’s peak had over 20 Million impressions per day.
