How is Page rank calculated?

[Jeana Anona]

You will never know what links Google counts towards your PageRank. The links that Google shows you are just a small sampling of the links it's using to calculate your PageRank. In fact it doesn't even show you your most valuable links usually.

Its depend on your content of your web pages and also depend on searching on your keywords.

PageRank in short is going to tell how strong the backlinks are but as you may guess many times even the low PageRank websites could be performing greatly over the net since PR is not the guaranteed way to reach the top spots on the Google pages.

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.

A page "votes" an amount of PageRank onto each page that it links to. The amount of PageRank that it has to vote with is a little less than its own PageRank value (its own value * 0.85). This value is shared equally between all the pages that it links to.

From this, we could conclude that a link from a page with PR4 and 5 outbound links is worth more than a link from a page with PR8 and 100 outbound links

It's Matt Cutts.

And, My simple piece of advice is to focus on improving ranking in search engines and generating quality traffic instead of focusing on how Page rank calculated and how to get high PR.

How is PageRank calculated

PR is calculated by the sharing of PR from all the IBL links to your page. This is not strictly accurate because Google also uses the internal links within a site in the calculation of PR. Each link to a page carries with it and passes PR value to the target page. The PR points or value passed depend on the PR value of the page they come from, and the total outbound links from the page. It is generally agreed that a page will only pass about 85% of its value to the page it links to. So a PR5 page with a single outbound link will pass 85% of the value of a PR5 page to the page it links to.
But virtually no page has only a single link remember internal links are also used in the total outbound link count so the value passed to any page is 85% of the PR, divided by the total number of outbound links.
The question now becomes what is the PR point value of the different PR levels. Most observers believe that the relationship between PR levels is logarithmic rather than linear. In other words PR5 is not worth 25% more than a PR4, but may be worth 4 to 6 times more.
It is also understood that a PR value is not a single number, but is in fact a range of values. So not all PR6s are equal. As the chart below shows a PR6 maybe just on the upper boundary of a PR5 or it maybe just short of the entry point for a PR7.
The chart that follows shows the range for each PR value. It also shows how much PR value or PR points a page with 50 outbound links will pass depending on of its own PR rank. From this I have calculated the number of links required from each value of PageRank necessary for a page to attain a desired page rank.

I believe even Google employees do not know exactly how PR is being calculated.

Great info here I also don't know how PR calculated. Thanks!

Its depend on your content of your web pages and also depend on searching on your keywords.

yeah, you are right but it depends on various things not only on web content. It depends on Back Links and Web Traffic also.

[HarryTruman]

Keyword-targeted campaigns are charged on a CPC (cost-per-click) basis. You are only charged when a user clicks on your ad and is taken to your landing page. The CPC rate depends on your maximum CPC bid (the most you're willing to pay per click) as well as Google's internal system of scoring keyword ads. Not only do you set your maximum CPC bid, but you decide on a maximum daily budget, so you never spend more than you have. Once you've spent your budget for that day, your ads won't appear until the next day

In simplest terms PR is calculated by the sharing of PR from all the IBL links to your page

PR is the numerical value assigned by the Google. Follow method is used to calculate the PR of a web page.

PR (A) = PR(B) + PR(C) + PR(D)
