Google Page Rank

Page Rank is a patented algorithm that has a working web site determine which is more important / popular. Page Rank is one of the main features of the Google search engine and was created by the founders, Larry Page and Sergey Brin is a Ph.D. student Stanford University.

A site will be more popular if more laying other sites that link that leads to the site, with the assumption that the content / site content is more useful from the content / content of other sites. Page Rank is calculated with a scale of 1-10.

Example: A site that have a Page Rank of 9 Sort will first in the list of Google search of sites that have a Page Rank 8 and then the next smaller.

How many search engines use in determining the quality / ranking of a web page, from the use META Tags, the contents of the document, the emphasis on content and many other techniques or combination of techniques that may be used. Link popularity, a technology developed to improve the lack of other technology (Meta Keywords, Meta Description), which can unfair with a special page designed for search engines is called regular or doorway pages. With the algorithm 'Page Rank' is, in each page will be inbound link (incoming link) and outbound links (links out) from each web page.

Page Rank, have the same basic concept of link popularity, but it does not only consider the "number of" inbound and outbound links. The approach used is a page will be considered important if other pages have a link to the page. A page will also become increasingly important if other pages have a rank (Page Rank) refers to the high page.

With the approach used by the Page Rank, the process occurs recursively where a ranking will be determined by the ranking of web pages that ranking determined by the ranking of web pages that have links to the page. This process means a process that repeatedly (recursive). In the virtual world, there are millions and even billions of web pages. Therefore, a web page ranking is determined from the link structure of the entire web page in the virtual world. A process which is very large and complex.
