Google's page rank: the Math behind the search engine

Approximately 94 million American adults use the internet on a typical day [24]. The number one internet activity is reading and writing email. Search engine use is next in line and continues to increase in popularity. In fact, survey findings indicate that nearly 60 million American adults use search engines on a given day. Even though there are many internet search engines, Google, Yahoo!, and MSN receive over 81% of all search requests [27]. Despite claims that the quality of search provided by Yahoo! and MSN now equals that of Google [11], Google continues to thrive as the search engine of choice receiving over 46% of all search requests, nearly double the volume of Yahoo! and over four times the volume of MSN.
