Hangzhou-based C2C & B2C e-commerce site Taobao released an updated version of its vertical shopping search engine ETao today. Changes include improved shopping guide channel search results and the addition of a group buy directory. ETao stated that search algorithms used on the home page of the previous version of the site weren’t sufficiently precise. The designer for the original version favored using all-purpose search algorithms, but changes in the updated version have been made specifically to provide users with search results which better reflect their shopping needs.
