MediaPost reports that Microsoft has added behavioral targeting features to the adCenter product. Microsoft has broken down Internet surfers into 18 audience segments including; mobile users, Internet power users, gamers, movie watchers, new/expecting moms, parents, and several categories encompassing travel searchers, and auto buyers and researchers. This now helps Microsoft stand apart from Google's AdWords product and Yahoo's Search Marketing product, PPC engines that currently do not have integrated behavioral targeting capabilities.
Postscript: Just got an email from an MSN rep that this story is not true. I quote; "The incorrect information is that you state BT (Behavioral Targeting) is available through adCenter, our paid search platform, where as BT (Behavioral Targeting) is only available for display ads."
