Personally, I wanted a bit more of the math, so I went back and read the full-length version of “The Anatomy of a Large-Scale Hypertextual Web Search Engine” (a natural first step). This was the paper written by Larry Page and Sergey Brin in 1997. Aka the paper in which they presented Google, published in the Stanford Computer Science Department. (Yes, it is long and I will be working a bit late tonight. All in good fun!)

When referring to the homepage, a trailing slash after the hostname is optional since it leads to the same content ("https://example.com/" is the same as "https://example.com"). For the path and filename, a trailing slash would be seen as a different URL (signaling either a file or a directory), for example, "https://example.com/fish" is not the same as "https://example.com/fish/".
A backlink is a reference comparable to a citation. The quantity, quality, and relevance of backlinks for a web page are among the factors that search engines like Google evaluate in order to estimate how important the page is.[2][3] PageRank calculates the score for each web page based on how all the web pages are connected among themselves, and is one of the variables that Google Search uses to determine how high a web page should go in search results.[4] This weighting of backlinks is analogous to citation analysis of books, scholarly papers, and academic journals.[1][3] A Topical PageRank has been researched and implemented as well, which gives more weight to backlinks coming from the page of a same topic as a target page. [5]
The best strategy to get backlinks is to create great content and let other people promote your content. However, to get started, you can create your own links to content on your social media platform, ask your friends to share your content on their websites and social media, and if you can find questions in forums that your content answers, you can always post it there.
Example: A blogger John Doe writes a very interesting article about a sports event. Another blogger Samantha Smith doesn’t agree with John’s article and writes about it in another article for an online magazine. She links to John’s article, so that her readers can understand both point of views. John’s blog gets a valuable backlink. On the other hand, Samantha’s article gets popular and many other websites link to her article. Samantha’s website gets many new backlinks. Even though John only got one backlink for his article, the value of his backlink is increased by the backlinks Samantha’s article generated.
In March 2006, KinderStart filed a lawsuit against Google over search engine rankings. KinderStart's website was removed from Google's index prior to the lawsuit and the amount of traffic to the site dropped by 70%. On March 16, 2007 the United States District Court for the Northern District of California (San Jose Division) dismissed KinderStart's complaint without leave to amend, and partially granted Google's motion for Rule 11 sanctions against KinderStart's attorney, requiring him to pay part of Google's legal expenses.[69][70]
Thanks to Google Search Console, Ahrefs, and, of course, Sitechecker you can easily check your website, look for 404 errors and proceed to their reclamation. It’s a very easy and effective way to boost the authority. We think that you can use several of the above-mentioned programs to examine your site in case one of them misses some 404 links. If you find some 404 errors, 301 redirect them to an appropriate webpage or to your homepage.

In a number of recent articles, where I've interviewed some of social media's rising stars such as Jason Stone from Millionaire Mentor, Sean Perelstein, who built StingHD into a global brand and Nathan Chan from Foundr Magazine, amongst several others, it's quite clear that multi-million-dollar businesses can be built on the backs of wildly-popular social media channels and platforms.


An omni-channel approach not only benefits consumers but also benefits business bottom line: Research suggests that customers spend more than double when purchasing through an omni-channel retailer as opposed to a single-channel retailer, and are often more loyal. This could be due to the ease of purchase and the wider availability of products.[24]
So enough of these scary stories. Google actually likes backlinks and relies upon them. The whole idea behind them is that they help to tell Google what is good and useful out there. Remember, it is still an algorithm. It doesn’t know that your page describing the best technique for restoring a 1965 Ford Mustang bumper is all that great. But if enough people are talking about how great it is, and thereby referencing that page on other websites, Google will actually know.

1. Now that we know that weight/PageRank/whatever will disappear (outside of the intrinsic wastage method that Google applies) when we use a ‘nofollow’ link, what do you think this will do to linking patterns? This is really a can of worms from an outbound linking and internal linking perspective. Will people still link to their ‘legals’ page from every page on their site? Turning comments ‘off’ will also be pretty tempting. I know this will devalue the sites in general, but we are not always dealing with logic here are we? (if we were you (as head of the web spam team) wouldn’t of had to change many things in the past. Changing the PageRank sculpting thing just being one of them).
I really appreciate that you keep us updated as soon as you can, but in some cases, e.g. WRT rel-nofollow, the most appreciated update would be the removal of this very much hated and pretty useless microformat. I mean, when you’ve introduced it because the Google (as well as M$, Yahoo and Ask) algos were flawed at this time, why not take the chance and dump it now when it’s no longer needed?
Try using Dribble to find designers with good portfolios. Contact them directly by upgrading your account to PRO status, for just $20 a year. Then simply use the search filter and type "infographics." After finding someone you like, click on "hire me" and send a message detailing your needs and requesting a price. Fiver is another place to find great designers willing to create inexpensive infographics.
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.

Great Post, I am agree with you. currently Google keeps change in algorithmic program methods thus in gift state of affairs everybody ought to have an honest quality website, quality content. Content is quality {and ought to|and will|and may} be contemporary on your web site and conjointly it should be associated with the subject. it’ll assist you in your ranking.


SEM, on the other hand, costs money but can deliver very rapid results. Your website must be optimized to make sales or at least drive a customer to get in touch (GIT – in marketing terms) so you can make a sale. You should approach SEM with care and make sure you completely understand how much money you have exposed at any one time. Start slow and evaluate your results.
What are backlinks doing for your SEO strategy? Well, Google considers over 200 SEO ranking factors when calculating where a page should rank, but we know that backlinks are one of the top three (the other two are content and RankBrain, Google’s AI). So while you should always focus on creating high-quality content, link-building is also an important factor in ranking your pages well on Google.
The leading search engines, such as Google, Bing and Yahoo!, use crawlers to find pages for their algorithmic search results. Pages that are linked from other search engine indexed pages do not need to be submitted because they are found automatically. The Yahoo! Directory and DMOZ, two major directories which closed in 2014 and 2017 respectively, both required manual submission and human editorial review.[39] Google offers Google Search Console, for which an XML Sitemap feed can be created and submitted for free to ensure that all pages are found, especially pages that are not discoverable by automatically following links[40] in addition to their URL submission console.[41] Yahoo! formerly operated a paid submission service that guaranteed crawling for a cost per click;[42] however, this practice was discontinued in 2009.

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.
So what happens when you have a page with “ten PageRank points” and ten outgoing links, and five of those links are nofollowed? […] Originally, the five links without nofollow would have flowed two points of PageRank each […] More than a year ago, Google changed how the PageRank flows so that the five links without nofollow would flow one point of PageRank each.

I think it is important you distinguish your advice about no-following INTERNAL links and no-following EXTERNAL links for user-generated content. Most popular UGC-heavy sites have no-followed links as they can’t possibly police them editorially & want to give some indication to the search engines that the links haven’t been editorially approved, but still might provide some user benefit.
Think about the words that a user might search for to find a piece of your content. Users who know a lot about the topic might use different keywords in their search queries than someone who is new to the topic. For example, a long-time football fan might search for [fifa], an acronym for the Fédération Internationale de Football Association, while a new fan might use a more general query like [football playoffs]. Anticipating these differences in search behavior and accounting for them while writing your content (using a good mix of keyword phrases) could produce positive results. Google Ads provides a handy Keyword Planner34 that helps you discover new keyword variations and see the approximate search volume for each keyword. Also, Google Search Console provides you with the top search queries your site appears for and the ones that led the most users to your site in the Performance Report35.

You may not want certain pages of your site crawled because they might not be useful to users if found in a search engine's search results. If you do want to prevent search engines from crawling your pages, Google Search Console has a friendly robots.txt generator to help you create this file. Note that if your site uses subdomains and you wish to have certain pages not crawled on a particular subdomain, you'll have to create a separate robots.txt file for that subdomain. For more information on robots.txt, we suggest this Webmaster Help Center guide on using robots.txt files13.
In this new world of digital transparency brands have to be very thoughtful in how they engage with current and potential customers. Consumers have an endless amount of data at their fingertips especially through social media channels, rating and review sites, blogs, and more. Unless brands actively engage in these conversations they lose the opportunity for helping guide their brand message and addressing customer concerns.
Online marketing, also called digital marketing, is the process of using the web and internet-connected services to promote your business and website. There are a number of disciplines within online marketing. Some of these include social media, search engine marketing (SEM), search engine optimization (SEO), email marketing, online advertising and mobile advertising.
Is very telling and an important thing to consider. Taking the model of a university paper on a particular subject as an example, you would expect the paper to cite (link to) other respected papers in the same field in order to demonstrate that it is couched in some authority. As PageRank is based on the citation model used in university work, it makes perfect sense to incorporate a “pages linked to” factor into the equation.
The goal of SEO is to get a web page high search engine ranking. The better a web page's search engine optimization, the higher a ranking it will achieve in search result listings. (Note that SEO is not the only factor that determines search engine page ranks.) This is especially critical because most people who use search engines only look at the first page or two of the search results, so for a page to get high traffic from a search engine, it has to be listed on those first two pages, and the higher the rank, the closer a page is to the number one listing, the better.  And whatever your web page's rank is, you want your website to be listed before your competitor's websites if your business is selling products or services over the internet.

To create an effective DMP, a business first needs to review the marketplace and set 'SMART' (Specific, Measurable, Actionable, Relevant and Time-Bound) objectives.[60] They can set SMART objectives by reviewing the current benchmarks and key performance indicators (KPIs) of the company and competitors. It is pertinent that the analytics used for the KPIs be customised to the type, objectives, mission and vision of the company.[61][62]
However, some of the world's top-earning blogs gross millions of dollars per month on autopilot. It's a great source of passive income and if you know what you're doing, you could earn a substantial living from it. You don't need millions of visitors per month to rake in the cash, but you do need to connect with your audience and have clarity in your voice.
But bear in mind that you can't guest post just anywhere and expect that it'll help. In fact, for years black hatters have perverted the value of guest posts by 'creating private blog networks,' which put out mass quantities of low-quality content for the sole purpose of exchanging backlinks. Google has caught on to this, and penalizes websites accordingly. So, you want to ensure that you only provide guest posts to reputable, respected websites that are relevant to your industry.
“Even when I joined the company in 2000, Google was doing more sophisticated link computation than you would observe from the classic PageRank papers. If you believe that Google stopped innovating in link analysis, that’s a flawed assumption. Although we still refer to it as PageRank, Google’s ability to compute reputation based on links has advanced considerably over the years.”
Matt, I’ve been a firm believer of the thought that webmasters shouldn’t really bother too much about the calculations that Google would do while spotting external links on a site. Leave that to Google. You write the content and if you find relevant resources, link to it. Why worry over PR ? In case you’re so sure about the linked site to be “kinda spammy” then nofollow it. That’s it.
If you are serious about improving web traffic to your website, we recommend you read Google Webmasters and Webmaster Guidelines. These contain the best practices to help Google (and other search engines) find, crawl, and index your website. After you have read them, you MUST try our Search Engine Optimization Tools to help you with Keyword Research, Link Building, Technical Optimization, Usability, Social Media Strategy and more.
Heading tags. Always use H tags to optimize your content layout. Try and use variations on your keyphrases in some headings, too. Don’t repeat keyphrases in headings unless it’s absolutely necessary. (This doesn’t stop you from needing to repeat the keyphrase in the body of your content). H tags are HTML codes – you can find a link to HTML codes and how to use them at the end of this section.

Using an omni-channel strategy is becoming increasingly important for enterprises who must adapt to the changing expectations of consumers who want ever-more sophisticated offerings throughout the purchasing journey. Retailers are increasingly focusing on their online presence, including online shops that operate alongside existing store-based outlets. The "endless aisle" within the retail space can lead consumers to purchase products online that fit their needs while retailers do not have to carry the inventory within the physical location of the store. Solely Internet-based retailers are also entering the market; some are establishing corresponding store-based outlets to provide personal services, professional help, and tangible experiences with their products.[24]
Brand awareness has been proven to work with more effectiveness in countries that are high in uncertainty avoidance, also these countries that have uncertainty avoidance; social media marketing works effectively. Yet brands must be careful not to be excessive on the use of this type of marketing, as well as solely relying on it as it may have implications that could negatively harness their image. Brands that represent themselves in an anthropomorphizing manner are more likely to succeed in situations where a brand is marketing to this demographic. "Since social media use can enhance the knowledge of the brand and thus decrease the uncertainty, it is possible that people with high uncertainty avoidance, such as the French, will particularly appreciate the high social media interaction with an anthropomorphized brand." Moreover, digital platform provides an ease to the brand and its customers to interact directly and exchange their motives virtually.[33]
What seems to be happening is that the toolbar looks at the URL of the page the browser is displaying and strips off everything down the last “/” (i.e. it goes to the “parent” page in URL terms). If Google has a Toolbar PR for that parent then it subtracts 1 and shows that as the Toolbar PR for this page. If there’s no PR for the parent it goes to the parent’s parent’s page, but subtracting 2, and so on all the way up to the root of your site.  If it can’t find a Toolbar PR to display in this way, that is if it doesn’t find a page with a real calculated PR, then the bar is greyed out.
I really appreciate that you keep us updated as soon as you can, but in some cases, e.g. WRT rel-nofollow, the most appreciated update would be the removal of this very much hated and pretty useless microformat. I mean, when you’ve introduced it because the Google (as well as M$, Yahoo and Ask) algos were flawed at this time, why not take the chance and dump it now when it’s no longer needed?
Google's founders, in their original paper,[18] reported that the PageRank algorithm for a network consisting of 322 million links (in-edges and out-edges) converges to within a tolerable limit in 52 iterations. The convergence in a network of half the above size took approximately 45 iterations. Through this data, they concluded the algorithm can be scaled very well and that the scaling factor for extremely large networks would be roughly linear in {\displaystyle \log n} , where n is the size of the network.

In December 2009, Google announced it would be using the web search history of all its users in order to populate search results.[32] On June 8, 2010 a new web indexing system called Google Caffeine was announced. Designed to allow users to find news results, forum posts and other content much sooner after publishing than before, Google caffeine was a change to the way Google updated its index in order to make things show up quicker on Google than before. According to Carrie Grimes, the software engineer who announced Caffeine for Google, "Caffeine provides 50 percent fresher results for web searches than our last index..."[33] Google Instant, real-time-search, was introduced in late 2010 in an attempt to make search results more timely and relevant. Historically site administrators have spent months or even years optimizing a website to increase search rankings. With the growth in popularity of social media sites and blogs the leading engines made changes to their algorithms to allow fresh content to rank quickly within the search results.[34]


It is interesting to read the article which however as others have commented leaves questions unanswered. The ideal internal page rank flow is clearly down the hierarchy and back up again evidently and no page to page links down the line. If this effect is big enough to have provoked an algorithm change then it must be substantial. Removing those related product links altogether would improve ranking and degrade the user experience of the site which surely is undesirable. I suspect the lesser of two evils was chosen.
A PageRank results from a mathematical algorithm based on the webgraph, created by all World Wide Web pages as nodes and hyperlinks as edges, taking into consideration authority hubs such as cnn.com or usa.gov. The rank value indicates an importance of a particular page. A hyperlink to a page counts as a vote of support. The PageRank of a page is defined recursively and depends on the number and PageRank metric of all pages that link to it ("incoming links"). A page that is linked to by many pages with high PageRank receives a high rank itself.
Excellent! I was wondering when Google would finally release information regarding this highly controversial issue. I have always agreed with and followed Matt’s advice in having PR flow as freely as possible, natural linking is always the best linking in my experience with my search engine experience and results. I am very glad that you have addressed the topic of nofollow links having no effects in the Google SERPs, I was getting tired of telling the same topics covered in this article to my clients and other “SEOs”.
Game advertising - In-Game advertising is defined as "inclusion of products or brands within a digital game."[49] The game allows brands or products to place ads within their game, either in a subtle manner or in the form of an advertisement banner. There are many factors that exist in whether brands are successful in their advertising of their brand/product, these being: Type of game, technical platform, 3-D and 4-D technology, game genre, congruity of brand and game, prominence of advertising within the game. Individual factors consist of attitudes towards placement advertisements, game involvement, product involvement, flow or entertainment. The attitude towards the advertising also takes into account not only the message shown but also the attitude towards the game. Dependent of how enjoyable the game is will determine how the brand is perceived, meaning if the game isn't very enjoyable the consumer may subconsciously have a negative attitude towards the brand/product being advertised. In terms of Integrated Marketing Communication "integration of advertising in digital games into the general advertising, communication, and marketing strategy of the firm"[49] is an important as it results in a more clarity about the brand/product and creates a larger overall effect.
After finding websites that have good metrics, you have to make sure the website is related to your site. For each competitor backlink, try to understand how your competitor got that link. If it was a guest article, send a request to become a contributor as well. If it was a product review by a blogger, contact the writer and offer them a good deal in exchange for a similar review.
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.
In my experience this means (the key words are “not the most effective way”) a page not scored by Google (“e.g. my private link” – password protected, disallowed via robots.txt and/or noindex meta robots) whether using or not using rel=”nofollow” attribute in ‘links to’ is not factored into anything… because it can’t factor in something it isn’t allowed.
The original Random Surfer PageRank patent from Stanford has expired. The Reasonable Surfer version of PageRank (assigned to Google) is newer than that one, and has been updated via a continuation patent at least once. The version of PageRank based upon a trusted seed set of sites (assigned to Google) has also been updated via a continuation patent and differs in many ways from the Stanford version of PageRank. It is likely that Google may be using one of the versions of PageRank that they have control over (the exclusive license to use Stanford’s version of PageRank has expired along with that patent). The updated versions of PageRank (reasonable surfer and Trusted Seeds approach) both are protected under present day patents assigned to Google, and both have been updated to reflect modern processes in how they are implemented. Because of their existence, and the expiration of the original, I would suggest that it is unlikely that the random surfer model-base PageRank is still being used.
Content marketing is more than just blogging. When executed correctly, content including articles, guides (like this one), webinars, and videos can be powerful growth drivers for your business. Focus on building trust and producing amazing quality. And most of all, make sure that you’re capturing the right metrics. Create content to generate ROI. Measure the right results. This chapter will teach you how.
As of October 2018 almost 4.2 billion people were active internet users and 3.4 billion were social media users (Statista). China, India and the United States rank ahead all other countries in terms of internet users. This gives a marketer an unprecedented number of customers to reach with product and service offerings, available 24 hours a day, seven days a week. The interactive nature of the internet facilitates immediate communication between businesses and consumers, allowing businesses to respond quickly to the needs of consumers and changes in the marketplace.
Description meta tags are important because Google might use them as snippets for your pages. Note that we say "might" because Google may choose to use a relevant section of your page's visible text if it does a good job of matching up with a user's query. Adding description meta tags to each of your pages is always a good practice in case Google cannot find a good selection of text to use in the snippet. The Webmaster Central Blog has informative posts on improving snippets with better description meta tags18 and better snippets for your users19. We also have a handy Help Center article on how to create good titles and snippets20.
After that, you need to make a choice about how to construct an online presence that helps you achieve that goal. Maybe you need to set up an e-commerce site. If you’re interested in publishing content to drive awareness and subscribers, look into setting up a blog. A simple website or landing page with a lead capture form can help you start developing your brand and generating traffic. A basic analytics platform (like Google Analytics, which is free) can help you start to measure how you are tracking towards your initial goal.
I find it amazing that youtube.com has been “nofollowing” its featured videos for last 12 months (still doing it as I type) when it now seems that this means “i dont trust this content” and “i want to page rank to flow to this content”. In fact a quick glance at a youtube page tells you that youtube are currently flushing 50% of their page rank (very approx) down the toilet on every page.
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!
Now, how much weight does PageRank carry? Like most every other part of the algorithm, it’s questionable. If we listed all the ranking factors, I don’t suspect it would be in the top 5, but it’s important to remember that the key to ranking well is to be the LESS IMPERFECT than your competition. IE: To have more of the right things that send the right signals in the right places so that Google sees you as a better, more relevant, candidate for the top three on page one. If you and your competitor both have optimized (on-page and technically) for the same keyword phrase perfectly, PR could be the deal breaker that pushes your blue link an inch up.
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.”

PageRank is a link analysis algorithm and it assigns a numerical weighting to each element of a hyperlinked set of documents, such as the World Wide Web, with the purpose of "measuring" its relative importance within the set. The algorithm may be applied to any collection of entities with reciprocal quotations and references. The numerical weight that it assigns to any given element E is referred to as the PageRank of E and denoted by {\displaystyle PR(E).} Other factors like Author Rank can contribute to the importance of an entity.
Using influencers to market your products or services is a great way to quickly saturate yourself into the marketplace, no matter what you're peddling. However, finding the right influencer at the right price is the hard part. You don't necessarily have to go to the top-tier influencers; you can also opt for micro-influencers (those that have 10,000 to 100,000 followers or fans).

First of all, it’s necessary to sort out what a backlink is. There is no need to explain everything in detail. The main thing to understand is what it is for and how it works. A backlink is a kind of Internet manipulator. It links one particular site with other external websites which contain links to this site. In other words, when you visit external sites they will lead you to that particular site.
Ask for explanations if something is unclear. If an SEO creates deceptive or misleading content on your behalf, such as doorway pages or "throwaway" domains, your site could be removed entirely from Google's index. Ultimately, you are responsible for the actions of any companies you hire, so it's best to be sure you know exactly how they intend to "help" you. If an SEO has FTP access to your server, they should be willing to explain all the changes they are making to your site.
A variety of methods can increase the prominence of a webpage within the search results. Cross linking between pages of the same website to provide more links to important pages may improve its visibility.[47] Writing content that includes frequently searched keyword phrase, so as to be relevant to a wide variety of search queries will tend to increase traffic.[47] Updating content so as to keep search engines crawling back frequently can give additional weight to a site. Adding relevant keywords to a web page's meta data, including the title tag and meta description, will tend to improve the relevancy of a site's search listings, thus increasing traffic. URL canonicalization of web pages accessible via multiple urls, using the canonical link element[48] or via 301 redirects can help make sure links to different versions of the url all count towards the page's link popularity score.
You may not want certain pages of your site crawled because they might not be useful to users if found in a search engine's search results. If you do want to prevent search engines from crawling your pages, Google Search Console has a friendly robots.txt generator to help you create this file. Note that if your site uses subdomains and you wish to have certain pages not crawled on a particular subdomain, you'll have to create a separate robots.txt file for that subdomain. For more information on robots.txt, we suggest this Webmaster Help Center guide on using robots.txt files13.
I think I did it by nature 🙂 I am just starting to learn all SEO and SERP stuffs. PageRank only entered my life when I quit the job last month. I don’t rush and I believe in a more natural way to get traffics, such as trying hard to create good contents and releasing some GPL works. You give something, and traffic flows in return. It’s Newton III Law. No sculpting, nor illegal way is necessary.
Despite this many people seem to get it wrong! In particular “Chris Ridings of www.searchenginesystems.net” has written a paper entitled “PageRank Explained: Everything you’ve always wanted to know about PageRank”, pointed to by many people, that contains a fundamental mistake early on in the explanation! Unfortunately this means some of the recommendations in the paper are not quite accurate.
