The formula uses a model of a random surfer who gets bored after several clicks and switches to a random page. The PageRank value of a page reflects the chance that the random surfer will land on that page by clicking on a link. It can be understood as a Markov chain in which the states are pages, and the transitions, which are all equally probable, are the links between pages.

The PageRank formula also contains a damping factor (d) . According to the PageRank theory, there is an imaginary surfer who is randomly clicking on links, and at some point he gets bored and eventually stops clicking. The probability that the person will continue clicking at any step is a damping factor. Thus, this factor is introduced to stop some pages having too much influence. As a result, their total vote is damped down by multiplying it by 0.85 (a generally assumed value).
If you can leave a guest post, leave it. Why? Because it can create relevant referral traffic to the website, you own. Everything you should do is to make your post valuable and without spam. Just important core information which won’t be spoiled by backlinks injecting. It’s better to have contextual linking. In other words, the links are to merge into your text.

Hi Matt, I have a question about PR: N/A. With the recent update I found many sites including mine went from PR: 3 to PR: N/A. I Googled for Site:mydomain.com to find it its banned, but I found its not banned, I posted this question on Google Webmaster forum and couple of other places but I didn’t get any help to fix it. I don’t know whom to ask, or how to figure this out. Could you please help me out please?
Was reviewing some competitive data and thought this was pretty interesting. I ran a batch analysis on Ahrefs of competitors. See attached screenshot. With just 603 backlinks, Our site is ranking up there with sites with 2x, 3x, 10x the number of backlinks/unique ips. Guessing some of this authority is coming from the backlinks program and general good quality of those links. Hard to speculate but nice to see. Ben R.
First, it’s important to know that not all backlinks are created equal. Those published on PR0 (“PR” stands for “page rank”—the “0” means the lowest value) sites offer very little weight in search; those published on PR9 (the highest page rank) sites offer very great weight in searches (in fact, a single backlink on a PR9 site might be enough to deliver top-three rankings for a keyphrase in some cases). Examples of high page rank sites include Wikipedia, the BBC, The New York Times, Mashable, etc.
(1 - d) - The (1 – d) bit at the beginning is a bit of probability math magic so the “sum of all web pages' PageRanks will be one”: it adds in the bit lost by the d(.... It also means that if a page has no links to it (no backlinks) even then it will still get a small PR of 0.15 (i.e. 1 – 0.85). (Aside: the Google paper says “the sum of all pages” but they mean the “the normalised sum” – otherwise known as “the average” to you and me.
I would like to know how Google is handling relevancy with so many websites now jumping on the “no follow” wagon? Seems like just about every major website has no follow links, so with the Panda updates this year what’s happening to all that lost link power? Seem’s like this tactic will stagnate the growth of up-and-coming websites on the internet to me. Am I right here?
I think that removing the link to the sitemap shouldn’t be a big problem for the navigation, but I wonder what happens with the disclaimer and the contact page? If nofollow doesn’t sink the linked page, how can we tell the search engine that these are not content pages. For some websites these are some of the most linked pages. And yes for some the contact page is worth gaining rank, but for my website is not.
