Ad management solution
OpenX is the company behind the free ad server for web publishers. The OpenX ad server makes it easy to include and manage the advertising on your website.
You can use it to manage banners of as many different types of ad networks (or self made banners) as you like across as many websites as you like. It provides options for banner capping, user & site based targeting, time or impression/click limited campaigns, and prioritization of campaigns.
You can review the statistical performance of a specific banner, campaign, advertiser, publisher or zone and re-prioritize your banners as needed.
