Page Rank

PageRank reflects our outlook of the significance of web pages by considering more than 500 million variables and 2 billion terms. Pages that we consider are important pages receive a higher PageRank and are further likely to appear at the top of the search results.

PageRank also considers the importance of each page that casts a vote, as votes from some pages are considered to have greater value, thus giving the linked web page superior value. We have always taken a practical approach to help improve search quality and create useful products, and our technology uses the collective intelligence of the web to verify a page's importance.
