PageRank is what Google uses to determine the importance of a web page. It ’ s one of many factors used to determine which 1 appear in search results. PageRank is also sometimes referred to by the slang term “ Google juice ” . PageRank was 2 by Google founders Larry Page and Sergey Brin at Stanford. In fact, the name PageRank is a likely play on Larry Page ’ s name. At the time that Page and Brin met, early search 3 typically linked to pages that had the highest keyword density, which meant people could game the system by repeating the same phrase over and over to 4 higher search page results. Sometimes web designers would even put hidden text on pages to repeat phrases. PageRank attempts to measure a web page ’ s importance.

The more often a 5 paper is cited by other papers, the more important that paper is deemed. This makes sense because people do tend to link to relevant 6 , and pages with more links to them are usually better resources than pages that nobody links. At the time it was developed, it was revolutionary. PageRank doesn ’ t stop at link popularity. It also looks at the importance of the page that 7 the link.
