San Jose-based eBay said today that it has unveiled a new affiliate program for the firm's eBay and Half.com web sites. The new affiliate program will encourage web site publishers to drive traffic to eBay, and replaces an existing offering eBay has offered since 2001. According to the site, it is replacing services from ValueClick's Commission Junction with the move. eBay said it has more than 100,000 affiliates globally. The move does not include Tradera AB, ProStores, Inc, Reseller Marketplace, Media Marketplace, eBay Stores and StubHub.
