About PageRank
PageRank - the method of broadcasting indexed websites referred to a numerical value, meaning its quality.
PageRank algorithm is used by popular Internet search engine Google. It was developed by Google founders Larry Page and Sergey Brin during their studies at Stanford University in 1998. Algorithm name comes not from the English word defining the page (English page), but the names of the authors, that is, Larry Page. Result PageRank is shown as one of the options available in the toolbar Google, you can check it in a number of independent sites.
PageRank is a development known for a long time heuristics, according to the quality of the text is in proportion to the number of texts it is claiming. Improvements proposed by the authors of the Google was weighing on the quality of links pointing to the text of their own PageRank value. In other words, if the text refers to the article, which itself has high scores, it is more important than where the same text invokes little popular party.
Methods similar to the algorithm, PageRank are now increasingly jigu inkoraggiti placed on the mechanisms of other search engines. Details correct algorithm has never been made public and are among the closely guarded secrets of Google. Until that are likely to gradually refined, in order to increase the efficiency of the mechanism. All information openly available only represent a model version of the algorithm used in the Google search engine. In addition, PageRank is only one of many elements that determine the final positions of the parties in the search results, and make the changes that he has increasingly less influence on it.
