There are simple and fast random walk-based distributed algorithms for computing PageRank of nodes in a network.[33] They present a simple algorithm that takes {\displaystyle O(\log n/\epsilon )} rounds with high probability on any graph (directed or undirected), where n is the network size and {\displaystyle \epsilon } is the reset probability ( {\displaystyle 1-\epsilon } is also called as damping factor) used in the PageRank computation. They also present a faster algorithm that takes {\displaystyle O({\sqrt {\log n}}/\epsilon )} rounds in undirected graphs. Both of the above algorithms are scalable, as each node processes and sends only small (polylogarithmic in n, the network size) number of bits per round.

And if you really want to know what are the most important, relevant pages to get links from, forget PageRank. Think search rank. Search for the words you’d like to rank for. See what pages come up tops in Google. Those are the most important and relevant pages you want to seek links from. That’s because Google is explicitly telling you that on the topic you searched for, these are the best.

I work on a site that allows users to find what they are looking for by clicking links that take them deeper and deeper into the site hierarchy. Content can be categorised in lots of different ways. After about three steps the difference between the results pages shown is of significance to a user but not to a search engine. I was about to add nofollow to links that took the browser deeper than 3 levels but after this announcement I won’t be…

Adjusting how Google treats nofollows is clearly a major shift (as the frenzy in the SEO community has demonstrated). So, if Google were to adjust how they treat nofollows they would need to phase it in gradually. I believe this latest (whether in 2008 or 2009) change is simply a move in the direction of greater changes to come regarding nofollow. It is the logical first step.
I just wanted to thank you for the awesome email of information. It was so awesome to see the results I have gotten and the results that your company has provided for other companies. Truly remarkable. I feel so blessed to be one of your clients. I do not feel worthy but do feel very blessed and appreciative to been a client for over 5 years now. My business would not be where it is today without you, your company and team. I sure love how you are dedicated to quality. I can not wait to see what the next 5 years bring with 10 years of internet marketing ninjas as my secret weapon. John B.
I have not at all seen the results I would expect in terms of page rank throughout my site. I have almost everything pointing at my home page, with a variety of anchor text, but my rank is 1. There is a page on my site with 3, though, and a couple with 2, so it certainly is not all about links; I do try to have somewhat unique and interesting content, but some of my strong pages are default page content. I will explore the help forum. (I guess these comments are nofollow :P) I would not mind a piece of this page rank …
So, the probability for the random surfer reaching one page is the sum of probabilities for the random surfer following links to this page. Now, this probability is reduced by the damping factor d. The justification within the Random Surfer Model, therefore, is that the surfer does not click on an infinite number of links, but gets bored sometimes and jumps to another page at random.
What's the authority of your website or webpage, or any other page on the internet for that matter where you're attempting to gain visibility? Authority is an important component of trust, and it relies heavily on quality links coming from websites that Google already trusts. Authority largely relates to the off-page optimization discipline of SEO that occurs away from the webpage as opposed to the on-page optimization that occurs directly on the webpage.
Also hadn’t thought about decreasing the rank value based on the spammyness of sites a page is linking into. My guess on how to do it would be determining the spammyness of individual pages based on multiple page and site factors, then some type of reverse pagerank calcuation starting with the those bad scores, then overlaying that on top of the “good” pagerank calculation as a penalty. This is another thing which would be interesting to play around with in the Nutch algorithm.
One more important thing to keep in mind is that this factor is just part of the story about what helps pages to be displayed high in SERPs. Yes, it was the first one used by Google, but now there are lots of ranking factors, they all matter, and they all are taken into account for ranking. The most essential one is deemed content. You know this, content is king, there is no way around it. User experience is the new black (with the new Speed Update, it will become even more important).

I agree that there is no point in trying to over analyze how the PageRank is flowing through your site. Just focus on great content. Link out when it actually helps the reader. This is what Google wants – for you to give good quality content to their users. So if you are doing that, they will reward you in the long run. No need to worry yourself with these types of link strategies.
Ah – well the Reasonable Surfer is a different patent (and therefore a different algorithm) to PageRank. I would imagine that initially, only the first link counted – simply because there either IS or IS NOT a relationship between the two nodes. This mean it was a binary choice. However, at Majestic we certainly think about two links between page A and Page B with separate anchor texts… in this case in a binary choice, either the data on the second link would need to be dropped or, the number of backlinks can start to get bloated. I wrote about this on Moz way back in 2011!
Hi Brian! You mentioned that we should have our anchor text include our target keyword. When I do that, Yoast SEO plugin throws a red flag that says “You’re linking to another page with the focus keyword you want this page to rank for. Consider changing that if you truly want this page to rank” So should I leave the anchor text with that keyword or change it?
Brian, you are such an inspiration. I wonder how do you get all these hacks and then publish them for all of us. I have been reading your stuff from quite a time now, but I have a problem. Every time I read something you post I feel overwhelmed but I haven’t been really able to generate any fruitful results on any of my sites. I just don’t know where to start. Imagine I don’t even have an email list.
Of course, it’s possible that the algorithm has some method of discounting internally reflected (and/or directly reciprocal) links (particularly those in identical headers or footers) to such an extent that this isn’t important. Evidence to support this the fact that many boring pages that are linked to by every page in a good site can have very low PR.
How does it work? In essence, you use Google Adwords (or another search engine’s equivalent – depending on the market you work in; in China, you’d be looking at Baidu, for example) to place bids on keyphrases; you write an advert based on that keyphrase; the search engine places the advert near the top of the search rankings, and you pay the amount of the bid every time someone clicks on your advert.
Backlinks are an essential part of SEO process. They help search bots to crawl your site and rank it correctly to its content. Each backlink is a part of a ranking puzzle. That`s why every website owner wants to get as much as possible backlinks due to improving website’s SEO ranking factors. It’s a type of citation or hyperlink used in the text. If a person says “to be or not to be,” he/she is citing Shakespeare’s character, Hamlet.

Matt, as you know, I was kind of annoyed when you suggested sculpting to a room full of SEOs back in 2007. We’d been told over the years to do things for humans, not to overly worry about having to do stuff for search engines — and suddenly, here you were suggesting that SEOs could flow PageRank to their most “important” pages. I’d figured Google had long since been smart enough to decide for itself what percentage of a page’s PageRank spend to assign to a particular link. That assumption didn’t just come out of the blue — it came from things Google had hinted at over the years. So being told to start overtly flowing around the PageRank? It seemed counter-productive.
In an effort to manually control the flow of PageRank among pages within a website, many webmasters practice what is known as PageRank Sculpting[65]—which is the act of strategically placing the nofollow attribute on certain internal links of a website in order to funnel PageRank towards those pages the webmaster deemed most important. This tactic has been used since the inception of the nofollow attribute, but may no longer be effective since Google announced that blocking PageRank transfer with nofollow does not redirect that PageRank to other links.[66]
