Anyone know the Pagerank formula?

Hello guys.

Anyone here know the # of backlinks and what PR the backlinks are that add up to caluculate your backlink?

Many thanks!

 

No one knows what exactly Google does - else everyone would be busy manipulating PR.

Webmasters have a limited knowledge of how PR works; which comes from work of founders of Google at Stanford university.

Here is a rough explanation of how PageRank works.

 

Backlinks, even with same PR aren't equal, so you can't say 'to get PRX you need X * PRX). This is far more complicated.

 

PR(A) = (1-d) + d (PR(T1)/C(T1) + ... + PR(Tn)/C(Tn))

Though to simplify that,

PR passed = (PR Of Linking Page(s)/The number of outgoing links) x dampening factor

The dampening factor is speculated to be around 0.85, though nobody knows the exact figure.

 

Check the document, i think you will get more clarity for that ... it seems that they have done some research in that area.

one more of googles secrets

 

No body knows the secret of page rank. But its very obvious and certain that when ever you have a great number of back links, you have a chance in getting listed

 

i thought the page rank algo had been given out ages ago.

just search google for page rank algorithm and take a look i have seen at least two explanations around it

ill try to find the link i had

 

Here is a quick chart:



It's a rough estimate, but you get the idea.

You have to love the people who don't bother reading the thread before they offer their 'advice'

 

Well, as long as you allow for a looser definition of "love", one that would encompass the overwhelming urge to stick red hot pins into them, or test out your newest voodoo doll collection on them, just to see it if works.

In that case I would agree with ya.

When do the pageranks get updated? once a month etc?

 

once in three months i think.

 

i think that depents on the power your backlinks. i have one web site which is pr 6 with 30 backlinks. but my backlinks are coming from pr7+ web sites

 

I'm surprised nobody referred to these guides which are pretty much considered authoritative.

A Comprehensive Guide to PageRank

And a graphical representation of PageRank

 

Nobody knows the page rank formula.
This : PR(A) = (1-d) + d (PR(T1)/C(T1) + ... + PR(Tn)/C(Tn)) is false or incomplete !
Sites must be related, you can't link a porn site to a book site.
Anyone can buy 10 000 sites or more , it's easy to reach pr4 or 5, you put a link on each single site to link to A site that in the end you'll have pr 9 or 10 ?
It's not gonna happen .
If someone knows the formula is a rich man !

 

Why?

Again this is wrong, sites don't have to be related in order to pass PR.
In order for the link to have a benefit in terms of search engine rankings than maybe they have to be realated in some way, but not PR.

Yep, look at Google, their PR10 is purely down to the number of links that they have, same with sites like Adobe and Yahoo

 

Everything mentioned here is speculative, no one except Google knows the answer to this question.

 

Good luck in breaking the code

 

No, you're completely wrong on multiple levels. In addition to what Matt said, you think that you can take 10,000 domains to PR4 or PR5 easily? Let's put aside for a moment the fact that 10k domains is going to cost you $80k/year, negating the "anyone can buy" part of that statement off the bat. The rest of it still shows your complete lack of understanding when it comes to scale and putting things into perspective, and that you have no clue how to read a chart.

Follow that chart out... it does not suggest that 10k PR4's and PR5's will give you a PR10... it suggests that 508,277 PR4's or 92,414 PR5's will. If you go for a mixture, then for the sake of argument let's say it would take a little over 300,000 of them to make a PR10 domain, assuming you can get them all indexed properly and none get banned, or anything like that.

However, let's go with the false assumption for the moment that getting a PR5 is "easy". Let's say that you can throw up a site and get it linked well enough so that next PageRank update that site goes to PR5, in just one day. Let's say that you do one of these "easy" sites every single day, consistently.

Even if we go with your original false statement that you only need 10,000... how long is this going to take you to finish?
