PageRankTM (PR)
is a numeric value that represents how important a website is online. Google becomes the idea that when a web site places a link (link) to another, is in fact a vote for the latter.
The more votes has a page will be considered more important by Google. Moreover, the importance of the page that casts the vote also determines the weight of this vote. In this way, Google calculates the importance of a page thanks to the votes received, taking into account the importance of each page that casts the vote.
PageRankTM (developed by the founders Larry Page and Sergey Brin)is the way Google decides the importance of a page. It is a valuable data because it is one of the factors that determine the position will have a page within the search results. It is not the only factor that Google uses to rank pages, but it is one of the most important.Sites containing more PR also generate more money.
Keep in mind that not all the links are taken into account by Google. For example, Google filters out and discards the links of pages devoted exclusively to put links (called 'link farms').
In addition, Google admits that a page can not control the links that point to it, but you can check the links page to other pages in place. Therefore, links to a page can not harm it, but it links a page to place penalized sites may be harmful to your PageRankTM.
If a site has PR0, it is usually a site penalized, and may not be intelligent to put a link to her.
One way to know a page is PageRankTM download it the Google search bar (only available for MS IExplorer). Bar appears in the one shown in green PageRankTM value on a scale of 0 to 10. PR10 websites are Yahoo, Microsoft, Adobe, Macromedia, and Google. You have a full list of PR10 sites.
