Last year, Taobao launched a partner marketing service called "Taobao Guest," causing quite a stir in the online earnings market. Before long, Taobao Guest became a popular emerging internet industry, and related Taobao Guest shopping guide websites began to appear in large numbers like mushrooms after rain. Another group of websites that promoted cashback on purchases (such as Yi Fanxian) also quickly supported the Taobao shopping cashback mechanism. Apart from competing for users with other Taobao Guests, the cashback websites presented an even more formidable challenge.
