    Hi all,

    I found a lot of people on here trying to figure out what exactly the big G's algorithm for calculating PR is. Like most of the stuff that Goog does, I thought it was random. I decided to do some digging and found the exact equation that they use.

    Code:
    We assume page A has pages T1...Tn which point to it (i.e., are citations). The parameter d is a damping factor which can be set between 0 and 1. We usually set d to 0.85. There are more details about d in the next section. Also C(A) is defined as the number of links going out of page A. The PageRank of a page A is given as follows:
    PR(A) = (1-d) + d (PR(T1)/C(T1) + ... + PR(Tn)/C(Tn))
    
    Note that the PageRanks form a probability distribution over web pages, so the sum of all web pages' PageRanks will be one.

    I'm sure some of you enterprising blackhatters will now advertising PR boosting services... ;)

    what is too bad about that page is that it does not have the date of when it was written, anywhere.

    Nothing new.. I think the formula is posted on the wikipedia page too. Pagerank has never been a secret.

    Page Rank is < 1/5000 of a ranking factor... No need to hype up a trivial ranking factor. I rank PR0's all day. lol

    Backlink Strategy is where it's at.

    There are to much formulas like this out there, it seems like everyone have its own formula how google algo works, when you listen to that douchebag Matt Cutts everything seems so easy, great content, link here, link there, post here post there and other deceiving shit they feeding us with, its all bullshit, i tested every shit they told.

    I had a blog i posted to every major social network, built posts, articles related to content, i made unique content, leave no footprints, exchanged links with related blogs, every shit you can imagine, i got PR1 after 6 months of work, fuck that.

    I got pissed, i have a blog with duplicated content, 4 months old blasted with scrapebox like crazy got into sandbox, posted to p0rn sites and every shit you can imagine, all the bad things, guess what i got PR4 today i got a PR3, i mean wtf.

    And i got a neutral blog with a duplicated content, i did nothing i got PR2 i have two backlinks indexed in bing search engine.

    Now you tell me what a hell is the answer on my shit.

    Page rank is dead. It's only kept around to confuse people... trustrank is what you want and NOBODY has figured that out yet.
