The thesis aims to examine Customer Management Relationship strategies used by different auction websites. The thesis used content analysis to investigate different auction websites with 32 website interactive functions, which can be classified into 8 categories. The research results found that auction websites had good performance in three categories of interactive functions(the website interactive interfacing, information offering, and individual options). It should be noted that two leading auction websites, namely Yahoo! and eBay, perform better than others in interactive interfacing. Roodo! is ranked the third and itemBay for cyber asset transactions the fourth. The result suggested that the auction websites should enhance sitemap navigating features, upgrade the webpage update rate, offer customer support activities, on-line surveys, routine raffle-drawing events, consolidate a customer-based community, and appealing on-line interactive games.
