We usually put some ads on our website or web application. We need a system to display different campaigns and monitor the performance of campaigns. Openads is the best open source ads management tool I have even seen. Tens of thousands of websites are using Openads to make money from online advertising.

Ads can come in all sorts of formats from images to movies, flash to popups and everything in between. Openads administrative interface lets you choose to enable or disable a campaign at any time.

Openads lets you run campaigns from many advertisers at the same time by loading ad program tags into Openads, e.g. Google Adsense, Double Click and Valueclick Media,etc.
