Well, Before I start my thread here, I was think, may be this forum is too old, so may be here some of are old members, who know more deeper about PageRank, but my assumption was wrong. Anyway, If someone also have same doubt about PageRank, so here is some of answered by me.

What is reality of PageRank, It is only floating value from 0 to 10?

Actually Real PR is something like that.

0 to xx PageRank - > Actual PR 0

xx To xxx PageRank -> Actual PR 1

xxx To xxxx Pagerank -> Actual PR 2

xxxx to xxxxx Pagerank -> Actual PR 3

xxxxx to xxxxxx pagerank -> Actual PR 4

...............................

xxxxxxxxxxx to infinity -> Actual PR 10

Here x is any number of PageRank, that number is log(n) based, it may be change privately by Google algo. For example, you got 0.1 PR from 100 webpage, then it's value is 0.1*100 = 10, so your Actual PR is 0 (You can even say, your PR is 0.5 or 0.6 in floating value), Similarly assume that, you got 0.2 PR from 1000 webpage, then it's value is 0.2*1000=200, so your Actual PR is 1.

So, that is the above reason, why PageRank is not increase after 10, because of infinity.

Dear cbp@ PR is always flow from one Page to another, no matter link is internal or external(just assume it is not nofollow). That is not myth, may be you are in sleep mode, sorry if my words hurt you.

Fathom and Chedders@ Well, I already read many of open source that talk about PR, So don't think, I have not read any document on that, Even I read all of web archive on PageRank.

Dumping factor d and q is both used to keep PageRank on specific webpage, for example A is linked to webpage B, C, and D, then all the PR, should not flow, so Page A also kept some PR, according to PR equation.

How PR calculated?

PR calculate every time, it may be on microseconds, or milliseconds. Also they did not wait for other page PR, for example, to calculate Page A, B , C rank, they did not wait for, what is PR of B and C, They use past value of B and C or if there is no any value then, may be they assign some value like 0.

Now, they star calculating PageRank of A, B, C, but as per PR question, you know that, each time, PR of all webpage is changed, because past value of PR of any page is changed, so every time, we get different PR for each webpage, So to solve that problem, they are using convergence i.e. PR of each webpage should continue to calculate until, there is no more difference between past and current PR. For example Let's take PR of Page A is calculated for first time is 0.57616 , second time 1.161616, third time 0.88663, 1.261916, 0.161946, 0.15966, 0.252466, 0.253466, 0. 253466, 0.253466, 0.253466.

So as you seen, the value is not changed after so many iteration, In reality it is not calculate by only 11, it is calculate by thousand time, until program does not get any different value then past value.

by d way thanks to Admin, for moving this thread to make it live for a long time

agrees : don't understand argun either
