To give advertisers the ability to reach customers looking for specific business categories in various geographic areas, online directory Whitepages.com has launched its behavioral targeting product, In-Market Targeting, MediaPost reports (via MediaBuyerPlanner). Revenue Science's technology powers the new offering, which lets marketers target users who are searching broad categories, such as "travel," and narrower categories such as "automobile dealerships." Marketers can then place targeted display advertisements on those users' searches.
