How Page Ranks Works !
Page Rank, page rank and all web masters are talking about! What's this other thing?PageRank is a numeric value that represents how important a page is on the web. Google figures that when one page links to another page, it is effectively casting a vote for the other page. The more votes that are cast for a page, the more important the page must be. Also, the importance of the page that is casting the vote determines how important the vote itself is. Google calculates a page's importance from the votes cast for it. How important each vote is is taken into account when a page's PageRank is calculated.
PageRank is Google's way of deciding a page's importance. It matters because it is one of the factors that determines a page's ranking in the search results. It isn't the only factor that Google uses to rank pages, but it is an important one.
How to increase your page rank ?
It's easy to increase page rank, simply by linking to other sites and also to be linked (this is what we call links exchange). You can also use my future service : http://hittracker.freehostia.com that will help you increase your Page Rank. PR don't mean that you have a huge number of visitor. You can have a high PR while you don't have visitors. But it's related! If you have a high PR Google will display your sites before others sites (that have less page ranks) Also if you have a high page rank this means that your site is linked by other sites that have high Page Rank (as they have a high page rank, they have good traffic) and then they direct traffic to you :) So as your Page Rank is higher as you have more visitors from sites that link to you and Google
How Page Rank is calculated ?
To calculate the PageRank for a page, all of its inbound links are taken into account. These are links from within the site and links from outside the site.
PR(A) = (1-d) + d(PR(t1)/C(t1) + ... + PR(tn)/C(tn))
That's the equation that calculates a page's PageRank. It's the original one that was published when PageRank was being developed, and it is probable that Google uses a variation of it but they aren't telling us what it is. It doesn't matter though, as this equation is good enough.
In the equation 't1 - tn' are pages linking to page A, 'C' is the number of outbound links that a page has and 'd' is a damping factor, usually set to 0.85.
We can think of it in a simpler way:-
a page's PageRank = 0.15 + 0.85 * (a "share" of the PageRank of every page that links to it)
"share" = the linking page's PageRank divided by the number of outbound links on the page.
How to know Sites linking to me and the Page Rank ?
To know sites that link to your site, type "link:http://yoursite.com" in google and google will search for you.
