Google on Tuesday released the final version of Ad Manager, free software that lets smaller online publishers deal with some elements of offering and planning advertisements.
The software can be used to manage advertising inventory, with features to help them sell ads, deliver them, and forecast demand. It can deal both with ads on a publisher's site and on affiliated network sites. And conveniently for Google, it can be integrated with Google's AdSense service, so Google can display its own ads for any unsold ad inventory. With AdSense, Google shares ad revenue with publishers.
Google announced the release on its AdSense blog
