I just finished setting up our communities to use OpenX, as a step in the direction of getting rid of Google Ads. As they describe on their home page:
“OpenX is a free, open source ad server that manages the selling and delivery of your online advertising inventory. You can get OpenX as a hosted service or as downloaded software.”
I am VERY impressed with the backend to help you set up advertisers, campaigns and banners. The only hickup I encountered was related to a delay due to caching of ads that prevents them from appearing for 20 minutes after you first set them up. Otherwise, it worked like a charm.
Here is a video tour of the platform, so you can see what I am talking about:
