What is PageRank?

It is a registered tradename by Google that makes reference to the patent of an algorithm whose objective is to assign of numerical way the relevance of a page Web by the motor search. This numerical reference is assigned mainly to wing amount and quality of connections that a page receives Web of others.
It defines it to Wikipedia as a democratic way that Google uses to determine the importance and trustworthiness of a Web site. That is to say, “Google interprets a connection of a page To a a page B as a vote, of the page To, for page B. But Google it watches beyond the volume of votes, or connections that a page receives; also it analyzes the page that emits the vote. The votes emitted by the considered pages “important�, that is to say with an elevated PageRank, are worth more, and help to do to other “important� pages. Therefore, the PageRank of a page reflects the importance of the same in Internet.�

How I can know whatever and as sites connect page?

The majority of the motors search throws the result of the sites that are connecting to you consulting directly in them with the syntax “Link� more “: � plus the name of the site, example [Link: www.phphostingreview.com].
In the case of Yahoo it will show all the sites that its robot has detected that they connect to your site, nevertheless in the case of Google will only show an extract of them, to be able to see the complete list you must do it through his application “Webmaster Tools� where once validated the property of you site will be able to see the sites that has detected they connect to your Web.

How many connections are equivalent to what PageRank?

We have found table that illustrates approximate of whichever connections need to determine PageRank, although this varies, since also you are important to determine the PageRank of site to know the PageRank the sites that connect to you, of which we will speak in the following article.

Table of PageRank relation

Algorithm of PageRank

The initial algorithm of PageRank can be found in the original document where their creators presented/displayed the prototype of Google “The Anatomy of to Large-Scale Hypertextual Web Search Engine�.

Algorithm of PageRank

Where:
•    PR (A) is the PageRank of page A.
•    d is a damping factor that has a value between 0 and 1.
•    PR (i) are the values of PageRank that have each one of the pages i that connect to A.
•    C (i) is the total number of salient connections of page i (are or not towards A).

Some experts assure that the value of variable d usually is 0,85. He represents the probability that a navigator continues pressing links when sailing by Internet instead of to write a URL directly in the bar of directions or to press one of his markers and is a value established by Google. Therefore, the probability that the user stops directly pressing links and navegue to another random Web is 1-d. The introduction of the factor of damping in the formula reduces something of weight to all the pages of Internet and obtains that the pages that do not have connections to no other page do not leave especially beneficiaries. If a user lands in a page without connections, which will do will be to sail randomly to any other page, which is equivalent to supposition that a page without salient connections has connections to all the pages of Internet.

Conclusion: An important part of the positioning in the motors search we can define it like a popularity contest, between but sites make reference and are tie to our Web site, better positioning we will have.
Then, we hoped that this information is to them of utility and waited for its commentaries.
