page rank

hi friends

how google calculated page ranks?...what is the techniques behind it?..

i knw google page rank related to back links,strong contents etc..
how it split to each pages like 3,4...??..

 

The algorithm used 'many' years back by Google to calculate PR was :

However now this formula is no more in play. PR now is all about backlinks/age/authority/link juice passed from homepage, etc...
No one really knows how the PR is calculated but sometimes it seems like its random as some webmasters report a gain in PR to a domain just a week old with no backlinks and which was never registered earlier.

 

Informative ! thanks for sharing , I noticed that a domain just a week old with no backlinks gained page rank on google updation can you tell how it occurs?

 

the most important is the backlink link, build more link automatically PR will increase

 

simply quality of back links.

 

PageRank is a link analysis algorithm developed by Google founders Larry Page and Sergey Brin. A number from one (lowest) to ten (highest) is assigned to a webpage as a measure of its importance, specifically the likelihood that a user will arrive at that page by randomly clicking Links. PageRank is not the same thing as Rank.

 

Pagerank calculation is already unknown to anyone except Google . I guess they have change the calculation from time to time or perhaps Google has its own method to check it which is really not known to us.. So when it comes to calculating pagerank only Google as idea about it

 

I am wondering where did you get this formula?

 

Ehh, well since someone threw out some math....

White papers, both new and old, are pretty easy to track down. Essentially, page rank has not been a usable metric in terms of SEO for years. It does help to identify a few things but nothing to write home about currently.

That stuff is at least a curious read.
