Yahoo! has joined Citysearch in utilizing DexOne’s (formerly RH Donnelley) Business.com site for B2B exposure and distribution:
Yahoo! advertisers now have the opportunity to have their paid search ads appear on select sites within the extensive Business.com Network, providing them with expanded opportunities to reach online customers. Simultaneously, users who search on Business.com Network sites now have additional results to choose from, thereby helping them find more products, services and businesses that best suit their needs.
Business.com claims 40 million uniques for its ad network, which contains a range of B2B sites such as Financial Times and AllBusiness.com. There’s some very targeted vertical exposure in these impressions/clicks.
