Page RankingPage ranking is one of the factors that determines your placement on the Google search engine. PageRank is a trademark of Google. PageRank was developed at Stanford University by Larry Page (hence the name Page Rank) and Sergey Brin as part of a project researching a new search engine. The project took three years to complete and led to the functional prototype known as Google and later became the full-fledged search engine Google we know now. While PageRank is just one of the many factors which determine the ranking of Google search results, it continues to provide the basis for all of Google's web search tools.PageRank is a probability distribution function used to represent the likelihood that a person randomly clicking on links will arrive at any particular page. PageRank can be calculated for any-size collection of documents (for example: the worldwide web). PageRank relies on the uniquely democratic nature of the web by using its vast link structure as an indicator of an individual page's value. In essence, Google interprets a link (see Linking) from page A to page B as a vote, by page A, for page B. But Google looks at more than the just the volume of votes, or links a page receives; it also analyzes the page that casts the vote. Votes cast by pages that are themselves 'important' weigh more heavily and help to make other pages 'important'. Important, high-quality sites receive a higher PageRank, which Google remembers each time it conducts a search. Of course, important pages mean nothing to you if they don't match your query (website theme). So Google combines PageRank with sophisticated text-matching techniques to find pages that are both important and relevant to your search. Google goes far beyond the number of times a term appears on a page and examines all aspects of the page's content (and the content of the pages linking to it) to determine if it's a good match for your query. Page ranking integrity and validity: Google's complex, automated methods make human tampering with the results extremely difficult. And though Google does run relevant ads above and next to the search results, Google does not sell placement within the results themselves ( i.e., no one can buy a higher PageRank). A Google search is an easy, honest and objective way to find high-quality websites with information relevant to your search. Google recalculates PageRank scores each time it crawls the Web and rebuilds its index. Find out how to find your page ranking |
