Abstract

Baidu, Sogou and Google are three main utilized search engines in China reported by Chinese Internet Date Centre (CNZZ) recently. During daily search in the Internet, it is easy to find that there are significant differences among the search rank indexes such as Baidu weight, Sogou rank and PageRank. As a result, the sequence of the search lists is totally different for a same keyword. On the other hand, some valuable articles in web as blogs in ScienceNet.cn are ignored by Baidu, Sogou and others. It is impossible to unify these ranking systems to a same level due to the business models from multi-enterprises. This paper studies the difference of ranking indexes of these search engines by analyzing 4 kinds of 42 websites in China. With the analyses of the correlation among these ranking indexes, averaged and weighted indexes, W-entropy rank index using information theory is proposed as a search ranking reference. With the property analyses, this new index demonstrates the ranking reality of Chinese websites. After the publication of this main idea in our blog, Baidu and Sogou adjusted their ranking indexes of some websites, achieving a better match with W-entropy rank index.
