Page rank is a ranking of sites from small to large provided by Google to determine the position where you will be positioned as a search engine google. For example I searched through google with certain keywords, the results of most of the position is a site that has a keyword and has a page rank is greatest. Although actually not so absolute as well this kind of system calculation algorithm.
Algorithm (formula) Page rank which was created by Larry Page one of which is the mainstay googleguys Google when searching. As a simple illustration of this PageRank formula is PR (A) = (1 – d) + d * SUM ((PR (I-> A) / C (I)), but this calculation is still a sort of secret of Google’s own party. Where PR (A) is the PageRank of sites A, “d” is the dumping factor (usually 0.85), PR (I-> A) is the PageRank of the sites link I to a site that led to the A, C (I) is the number of links from site I, ((PR (I-> A) / C (I)) is the amount of PageRank received from site A web site that led to the site A.
But in my opinion, it’s all just a formula to simplify the approximate count of people, who know exactly will this formula is Lary Page. A few simple tips you can do to increase the pagerank of them are not arbitrarily give you a link to someone else, but it is recommended to accept links from sites that have a higher PageRank. Why PageRank is so important for us then? Because according to several people who had to his online business, especially following the program paid to review, it was a start-up for you to get the job done a lot of review, because advertisers generally prefer the pagerank of how much we have.
