Suppose instead that page B had a link to pages C and A, page C had a link to page A, and page D had links to all three pages. Thus, upon the first iteration, page B would transfer half of its existing value, or 0.125, to page A and the other half, or 0.125, to page C. Page C would transfer all of its existing value, 0.25, to the only page it links to, A. Since D had three outbound links, it would transfer one third of its existing value, or approximately 0.083, to A. At the completion of this iteration, page A will have a PageRank of approximately 0.458.
Google wasn’t happy with the Pandora’s Box it had opened. It began to fight back, with its most famous action against a network known as SearchKing, penalizing the site and some of those in the network with PageRank score reductions or actual removal from Google. SearchKing sued Google. Google won, a judge ruling that its search results were entitled to First Amendment protection as opinions.
PageRank has been used to rank public spaces or streets, predicting traffic flow and human movement in these areas. The algorithm is run over a graph which contains intersections connected by roads, where the PageRank score reflects the tendency of people to park, or end their journey, on each street. This is described in more detail in "Self-organized Natural Roads for Predicting Traffic Flow: A Sensitivity Study".
Hi Bill, Yes – thanks. I think I’ll have to do more of these. I couldn’t really go beyond Pagerank in an 18 minute Pubcon session. Although the random surfer model expired (and wasn’t even assigned to Google), it is still a precursor to understanding everything that has come after it. I think I would love to do more videos/presentations on both Reasonable surfer patent, Dangling Nodes and probably a lifetime of other videos in the future. To be able to demonstrate these concept without giving people headaches, though, the PageRank algorithm in Matrix form provides a good understanding of why you can’t "just get links" and expect everything to be at number 1.
I love the broken-link building method because it works perfectly to create one-way backlinks. The technique involves contacting a webmaster to report broken links on his/her website. At the same time, you recommend other websites to replace that link. And here, of course, you mention your own website. Because you are doing the webmaster a favor by reporting the broken links, the chances of a backlink back to your website are high.
The nofollow tag is being used for page rank sculpting and to stop blog spamming. In my mind this is tant amount to manipulating page rank and thus possibly ranking position in certain cases. I do post to regularly blogs and forums regarding web design and this improved my search ranking as a side effect. Whats wrong with making an active contribution to the industry blogs and being passed some Pagerank. Google needs to determine whether the post entry is relevant then decide to pass pagerank after the analysis or just decide that blog should not pass PR in any event. Whats gone wrong with the Internet when legitimate content pages do not pass PR?
I was exactly thinking the same thing what Danny Sullivan had said. If comments (even with nofollow) directly affect the outgoing PR distribution, people will tend to allow less comments (maybe usage of iframes even). Is he right? Maybe, Google should develop a new tag as well something like rel=”commented” to inform spiders about it to give less value and wordpress should be installed default with this attribute 🙂
2. Does a nofollowed INTERNAL link also bleed PageRank? Doesn’t that actively punish webmasters who use nofollow in completely . I think Danny makes the case that nofollow at the link level isn’t a cure for duplicate content, but many hosted sites and blogs don’t have the full range of technical options at their disposal. I myself use a hosted service that’s excellent for SEO in many ways but doesn’t give me a per-page HTML header in which to put a canonical link tag. Conclusion: Google would rather we NOT hide duplicate content if nofollow is the most straightforward way to do it.
Well, to make things worse, website owners quickly realized they could exploit this weakness by resorting to “keyword stuffing,” a practice that simply involved creating websites with massive lists of keywords and making money off of the ad revenue they generated. This made search engines largely worthless, and weakened the usefulness of the Internet as a whole. How could this problem be fixed?
Some backlinks are inherently more valuable than others. Followed backlinks from trustworthy, popular, high-authority sites are considered the most desirable backlinks to earn, while backlinks from low-authority, potentially spammy sites are typically at the other end of the spectrum. Whether or not a link is followed (i.e. whether a site owner specifically instructs search engines to pass, or not pass, link equity) is certainly relevant, but don't entirely discount the value of nofollow links. Even just being mentioned on high-quality websites can give your brand a boost.
Backlinks can be time-consuming to earn. New sites or those expanding their keyword footprint may find it difficult to know where to start when it comes to link building. That's where competitive backlink research comes in: By examining the backlink profile (the collection of pages and domains linking to a website) to a competitor that's already ranking well for your target keywords, you can gain insight about the link building that may have helped them. A tool like Link Explorer can help uncover these links so you can and target those domains in your own link building campaigns.
Advanced link analysis includes differentiating between sections of pages and treating links differently. What makes you think G or other engines treat links in the editorial section and comments section of the webpages the same as each other. Especially for those content management systems that are widely in use like wordpress, joomla, etc. The advice here is helpful and has nothing to do with creating a nightmare. All those who are asking questions here and envision a nightmare would agree that links in the footer section are treated differently. How is that possible if sections on a page are not classified and treated differently.

6. Measurement and analysis. You won’t get far in SEO unless you know how to measure your results, interpret those results, and use your analysis to make meaningful changes to your approach. The best tool for the job is still Google Analytics, especially if you’re new to the game. Spend some time experimenting with different metrics and reports, and read up on Analytics knowledge base articles. There’s a deep world to dive into.

Another tool to help you with your link building campaign is the Backlink Builder Tool. It is not enough just to have a large number of inbound links pointing to your site. Rather, you need to have a large number of QUALITY inbound links. This tool searches for websites that have a related theme to your website which are likely to add your link to their website. You specify a particular keyword or keyword phrase, and then the tool seeks out related sites for you. This helps to simplify your backlink building efforts by helping you create quality, relevant backlinks to your site, and making the job easier in the process.
All of the examples above and more could be used as anchor text for the same backlink. Google will index each differently. Not only that, Google will even examine the few words before and after the anchor text as well as take into account all of the text on the page. It will also attribute value to which backlink was first in the page and diminish the value for each following link.
Online networking, when executed correctly, allows you to build valuable relationships in online forums and groups that can help you advance your business. You could meet peers and fellow experts with whom you could collaborate or partner up with for a project, or you could provide value to your target audience by sharing your knowledge and winning over some customers as a result. No matter what, though, the goal with this type of marketing is purely relationship building and not selling outright.
Structured data21 is code that you can add to your sites' pages to describe your content to search engines, so they can better understand what's on your pages. Search engines can use this understanding to display your content in useful (and eye-catching!) ways in search results. That, in turn, can help you attract just the right kind of customers for your business.
1. Apparently, external linking of any kind bleeds PR from the page. Following or nofollowing becomes a function of whether you want that lost PR to benefit the other site. Since nofollow has ceased to provide the benefit of retaining pagerank, the only reason to use it at all is Google Might Think This Link Is Paid. Conclusion: Google is disincentivizing external links of any kind.
“With 150 million pages, the Web had 1.7 billion edges (links).” Kevin Heisler, that ratio holds true pretty well as the web gets bigger. A good rule of thumb is that the number of links is about 10x the number of pages. I agree that it’s pretty tragic that Rajeev Motwani was a co-author of many of those early papers. I got to talk to Rajeev a little bit at Google, and he was a truly decent and generous man. What has heartened me is to see all the people that he helped, and to see those people pay their respects online. No worries on the Consumer WebWatch–I’m a big fan of Consumer WebWatch, and somehow I just missed their blog. I just want to reiterate that even though this feels like a huge change to a certain segment of SEOs, in practical terms this change really doesn’t affect rankings very much at all.

If (a) is correct that looks like bad news for webmasters, BUT if (b) is also correct then – because PR is ultimately calculated over the whole of the web – every page loses out relative to every other page. In other words, there is less PR on the web as a whole and, after a sufficient number of iterations in the PR calculation, normality is restored. Is this correct?


Matt, this is an excellent summary. I finally got around to reading “The Search” by John Battelle and it was very enlightening to understand much of the academia behind what led to the creation of Backrub.. er Google.Looking at how many times the project was almost shutdown due to bandwidth consumption (> 50% of what the university could offer at times) as well as webmasters being concerned that their pages would be stolen and recreated. It’s so interesting to see that issues we see today are some of the same ones that Larry and Sergey were dealing with back then. As always, thanks for the great read Matt!
Backlink is a link one website gets from another website. Backlinks make a huge impact on a website’s prominence in search engine results. This is why they are considered very useful for improving a website’s SEO ranking. Search engines calculate rankings using multiple factors to display search results. No one knows for sure how much weight search engines give to backlinks when listing results, however what we do know for certain is that they are very important.

Google will like your content if your clients like it. The content should be helpful and contain less information which is already known to the reader. It is to meet their expectations. When users vote for your site, it means that Google starts accepting it as an authority site. That’s why content writing is as important as a speech of a candidate for the Presidency. The better it is, the more visitors you have.


Google works because it relies on the millions of individuals posting links on websites to help determine which other sites offer content of value. Google assesses the importance of every web page using a variety of techniques, including its patented PageRank™ algorithm which analyzes which sites have been “voted” the best sources of information by other pages across the web.
The truth? Today, rising above the noise and achieving any semblance of visibility has become a monumental undertaking. While we might prevail at searching, we fail at being found. How are we supposed to get notice while swimming in a sea of misinformation and disinformation? We've become immersed in this guru gauntlet where one expert after another is attempting to teach us how we can get the proverbial word out about our businesses and achieve visibility to drive more leads and sales, but we all still seem to be lost.

An entrepreneur or freelancer has two main strategies to tap into when marketing online. Search Engine Optimization (SEO), which attempts to rank your website on search engines “organically”, and Search Engine Marketing (SEM), which ranks your website in search results in exchange for money. Both strategies can be used to build a business successfully—but which one is right for you?
It doesn’t mean than you have to advertise on these social media platforms. It means that they belong to that pyramid which will function better thanks to their support. Just secure them and decide which of them will suit your goal better. For example, you can choose Instagram because its audience is the most suitable for mobile devices and bits of advice of their exploitation distribution.

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 …
Search engines find and catalog web pages through spidering (also known as webcrawling) software. Spidering software "crawls" through the internet and grabs information from websites which is used to build search engine indexes. Unfortunately, not all search engine spidering software works the same way, so what gives a page a high ranking on one search engine may not necessarily give it a high ranking on another. Note that rather than waiting for a search engine to discover a newly created page, web designers can submit the page directly to search engines for cataloging.
My favorite tool to spy on my competitors' backlinks is called Monitor Backlinks. It allows you to add your four most important competitors. From then on, you get a weekly report containing all the new links they have earned. Inside the tool, you get more insights about these links and can sort them by their value and other SEO metrics. A useful feature is that all the links my own website already has are highlighted in green, as in the screenshot below.
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.
