When calculating PageRank, pages with no outbound links are assumed to link out to all other pages in the collection. Their PageRank scores are therefore divided evenly among all other pages. In other words, to be fair with pages that are not sinks, these random transitions are added to all nodes in the Web. This residual probability, d, is usually set to 0.85, estimated from the frequency that an average surfer uses his or her browser's bookmark feature. So, the equation is as follows:
Google uses a hyperlink based algorithm (known as ‘PageRank’) to calculate the popularity and authority of a page, and while Google is far more sophisticated today, this is still a fundamental signal in ranking. SEO can therefore also include activity to help improve the number and quality of ‘inbound links’ to a website, from other websites. This activity has historically been known as ‘link building’, but is really just marketing a brand with an emphasis online, through content or digital PR for example.
Collaborative Environment: A collaborative environment can be set up between the organization, the technology service provider, and the digital agencies to optimize effort, resource sharing, reusability and communications. Additionally, organizations are inviting their customers to help them better understand how to service them. This source of data is called User Generated Content. Much of this is acquired via company websites where the organization invites people to share ideas that are then evaluated by other users of the site. The most popular ideas are evaluated and implemented in some form. Using this method of acquiring data and developing new products can foster the organizations relationship with their customer as well as spawn ideas that would otherwise be overlooked. UGC is low-cost advertising as it is directly from the consumers and can save advertising costs for the organisation.
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?
7. Keyword research. Specific target keywords aren’t as important for SEO success as they used to be, now that Google search is fueled by semantic and contextual understanding, but you should still be able to identify both head keyword (short, high-volume keywords) and long-tail keyword (longer, conversational, low-volume keywords) targets to guide the direction of your campaign.
This is what happens to the numbers after 15 iterations…. Look at how the 5 nodes are all stabilizing to the same numbers. If we had started with all pages being 1, by the way, which is what most people tell you to do, this would have taken many more iterations to get to a stable set of numbers (and in fact – in this model – would not have stabilized at all)
Danny, I was on the panel where Matt suggested that and I point blank asked on stage what happened when folks starting abusing the tactic and Google changed their mind if you recall (at the time, I’d seen some of the things being done I knew Google would clarify as abuse and was still a nofollow unenthusiast s a result at that time). And Matt dismissed it. So, I think you can take home two important things from that – 1. SEO tactics can always change regardless of who first endorses them and 2. Not everything Matt says is etched in stone. <3 ya Matt.

“What does mean relevancy?”, – you may ask. Let’s imagine that you have blog about website building tips, but you have found an authoritative site about makeup trends. According to Google, this source won`t be a perfect one for you, because high authority sites should be closely related to yours. In other cases, it won’t work. The same thing goes for the content around which your link is inserted.
Do you regularly publish helpful, useful articles, videos or other types of media that are popular and well produced? Do you write for actual human beings rather than the search engine itself? Well, you should. Latest research from Searchmetrics on ranking factors indicates that Google is moving further towards longer-form content that understands a visitor’s intention as a whole, instead of using keywords based on popular search queries to create content.
The numbers didn’t quite sit right with me because there didn’t seem to be enough juicy inbound links to the winning page. Then I noticed that two key links were missing from the 10 node chart with the PageRank metrics on it when compared to the previous chart without the metrics. The two missing links are the two coming from node 2 to node 1. Suddenly it all made sense again and it was obvious why that page won.
What an amazing and informative post! One other option you left out was wikkigrabber. and how not many people use this option! Google wikki grabber, type in keywords and find articles missing links etc on Wikipedia, edit a post with what was missing (make sure it is relevant to the article or post otherwise it will be removed) and them boom! Quality, powerful backlink!
“There may be a miniscule number of pages (such as links to a shopping cart or to a login page) that I might add nofollow on, just because those pages are different for every user and they aren’t that helpful to show up in search engines” – it doesn`t make much sense. If a page isn`t helpful and should not show up on search results, the best option is to meta-noindex the page and disallow it on robots.txt.
If you are serious about improving web traffic to your website, we recommend you read Google Webmasters and Webmaster Guidelines.

This pagerank theme is getting understood in simplistic ways, people are still concerning about pagerank all the time (talking about SEOs). I just use common sense, if I were the designer of a search engine, besides of using the regular structure of analysis, I would use artificial intelligence to determine many factors of the analysis. I think this is not just a matter of dividing by 10, is far more complex. I might be wrong, but I believe the use of the nofollow attribute is not a final decision of the website owner any more is more like an option given to the bot, either to accept or reject the link as valid vote. Perhaps regular links are not final decision of the webmaster too. I think Google is seeing websites human would do, the pages are not analyzed like a parser will do, I believe is more like a neural network, bit more complex. I believe this change make a little difference. People should stop worrying about pagerank and start building good content, the algorithm is far more complex to determine what is next step to reach top ten at Google. However nothing is impossible.
A backlink is simply a link from another domain pointing back to your site. Simple, right? Well, yes and no. Not all backlinks are created equal, and there are a few rules you need to observe in order for them to benefit your site’s ranking. For example, your link needs to be a clickable hyperlink with anchor text; for example, www. conductor .com won’t help us in link building, but www.conductor.com will.
Great post. I’m posting a link back to this article from our blog along with some comments. I do have a question. In your article, you post “The only place I deliberately add a nofollow is on the link to my feed, because it’s not super-helpful to have RSS/Atom feeds in web search results.” Yet when I look at this article, I noticed that the comment links are “external, nofollow”. Is there a reason for that?
Content is king. Your content needs to be written so that it provides value to your audience. It should be a mix of long and short posts on your blog or website. You should not try to “keyphrase stuff” (mentioning a keyphrase over and over again to try and attract search engines) as this gets penalized by search engines now. However, your text should contain the most important keyphrases at least once and ideally two to three times—ideally, it should appear in your title. However, readability and value are much more important than keyword positioning today.
Content is king. It always has been and it always will be. Creating insightful, engaging and unique content should be at the heart of any online marketing strategy. Too often, people simply don't obey this rule. The problem? This takes an extraordinary amount of work. However, anyone that tells you that content isn't important, is not being fully transparent with you. You cannot excel in marketing anything on the internet without having quality content.
For the purpose of their second paper, Brin, Page, and their coauthors took PageRank for a spin by incorporating it into an experimental search engine, and then compared its performance to AltaVista, one of the most popular search engines on the Web at that time. Their paper included a screenshot comparing the two engines’ results for the word “university.”
“NOTE: You may be curious what your site’s or your competitor’s PR score is. But Google no longer reveals the PageRank score for websites. It used to display at the top of web browsers right in the Google Toolbar, but no more. And PR data is no longer available to developers through APIs, either. Even though it’s now hidden from public view, however, PageRank remains an important ingredient in Google’s secret ranking algorithms.”
Chris_D, great question. If you have a single product page that can have multiple urls with slightly different parameters, that’s a great time to use a rel=canonical meta tag. You can use rel=canonical for pages with session IDs in a similar fashion. What rel=canonical lets you do is say “this page X on my host is kinda of ugly or otherwise isn’t the best version of this page. Use url Y as the preferred version of my page instead.” You can read about rel=canonical at http://www.google.com/support/webmasters/bin/answer.py?hl=en&answer=139394. Bear in mind that if you can make your site work without session IDs or make it so that you don’t have multiple “aliases” for the same page, that’s even better because it solves the problem at the root.
