Google recently substituted their Google Admanager product for Dart for Publishers
(DFP) Small Business. The new DFP is a great product and best of all: free.
DFP offers some very interesting targeting capabilities within their adserver - and great geographic targeting. However, true behavioral targeted (BT) ads is not offered in their platform. But with the BTBuckets + DFP integration
you can now segment ads based on clusters created within BTBuckets.
Happy early Xmas,
