PageRank was influenced by citation analysis, early developed by Eugene Garfield in the 1950s at the University of Pennsylvania, and by Hyper Search, developed by Massimo Marchiori at the University of Padua. In the same year PageRank was introduced (1998), Jon Kleinberg published his work on HITS. Google's founders cite Garfield, Marchiori, and Kleinberg in their original papers.[5][18]
Influencer marketing: Important nodes are identified within related communities, known as influencers. This is becoming an important concept in digital targeting. It is possible to reach influencers via paid advertising, such as Facebook Advertising or Google Adwords campaigns, or through sophisticated sCRM (social customer relationship management) software, such as SAP C4C, Microsoft Dynamics, Sage CRM and Salesforce CRM. Many universities now focus, at Masters level, on engagement strategies for influencers. 

As I was telling Norman above, these days what we’ve come to call content marketing is really a big part of “link building.” You can’t buy links, and “you link to me I’ll link to you” requests often land on deaf ears. Its really all about creating high quality content (videos, images, written blog posts) that appeals to the needs/wants of your target market, and then naturally earning inbound links from sources that truly find what you have to offer worth referencing.
My main concern though, is Google appears to becoming reliant on sites doing MANY things for SE only. It also appears that Google is lowering the bar for YouTube videos in the organic SERPs and forcing their insertion as the cost of relevant pages. It even seems they are now doing the same for pictures, despite BOTH having their own SEs. I fear Google is attempting to increase profits, for it’s shareholders, in a rather impatient manner.
“So what happens when you have a page with “ten PageRank points” and ten outgoing links, and five of those links are nofollowed? Let’s leave aside the decay factor to focus on the core part of the question. Originally, the five links without nofollow would have flowed two points of PageRank each (in essence, the nofollowed links didn’t count toward the denominator when dividing PageRank by the outdegree of the page). 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.”
For instance, you might use Facebook’s Lookalike Audiences to get your message in front of an audience similar to your core demographic. Or, you could pay a social media influencer to share images of your products to her already well-established community. Paid social media can attract new customers to your brand or product, but you’ll want to conduct market research and A/B testing before investing too much in one social media channel.
Search engines often use the number of backlinks that a website has as one of the most important factors for determining that website's search engine ranking, popularity and importance. Google's description of its PageRank system, for instance, notes that "Google interprets a link from page A to page B as a vote, by page A, for page B."[6] Knowledge of this form of search engine rankings has fueled a portion of the SEO industry commonly termed linkspam, where a company attempts to place as many inbound links as possible to their site regardless of the context of the originating site. The significance of search engine rankings is pretty high, and it is regarded as a crucial parameter in online business and the conversion rate of visitors to any website, particularly when it comes to online shopping. Blog commenting, guest blogging, article submission, press release distribution, social media engagements, and forum posting can be used to increase backlinks.
So, for example, a short-tail keyphrase might be “Logo design”. Putting that into Google will get you an awful lot of hits. There’s a lot of competition for that phrase, and it’s not particularly useful for your business, either. There are no buying signals in the phrase – so many people will use this phrase to learn about logo design or to examine other aspects of logo design work.

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.
I won’t blame MC. Google, knows what they does. These are things that webmasters need not worry about. Well, it won’t make much difference as far as I think. I don’t use no follow tags specifically – I use WP for blogging purposes and it does rest of the things for me other than writing content which I do. I think it is the content and the external links that sites point to – which should be considered. I mean, if a computer blog owner posts a really fantastic computer article about something related to computer, and also puts some links to external pages (which are really useful for the readers), then that post, should be ranked high in gooogle – And I think google does this well – So, webmasters, just concentrate on yur website/blogs etc and leave rest of the things to Big G.

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 🙂
nofollow is beyond a joke now. There is so much confusion (especially when other engines’ treatment is factored in), I don’t know how you expect a regular publisher to keep up. The expectation seems to have shifted from “Do it for humans and all else will follow” to “Hang on our every word, do what we say, if we change our minds then change everything” and nofollow lead the way. I could give other examples of this attitude (e.g. “We don’t follow JavaScript links so it’s ’safe’ to use those for paid links”), but nofollow is surely the worst.

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”.

We regard a small web consisting of three pages A, B and C, whereby page A links to the pages B and C, page B links to page C and page C links to page A. According to Page and Brin, the damping factor d is usually set to 0.85, but to keep the calculation simple we set it to 0.5. The exact value of the damping factor d admittedly has effects on PageRank, but it does not influence the fundamental principles of PageRank. So, we get the following equations for the PageRank calculation:

Such an enlightening post! Thanks for revealing those sources, Brian. This really has opened up my mind to the new ideas. I have read many articles about SEO, especially the ones in my country, most of them don’t really tell how to increase your presence in search engines. But today I found this page, which gave me much more valuable insights. Definitely going to try your tips..
This will give you an indication of how many times a search is performed in a month (low numbers are not very useful unless there is a very clear buying signal in the keyphrase – working hard for five hits a month is not recommended in most cases) and how much the phrase is “worth” per click to advertisers (e.g., how much someone will pay to use that keyphrase). The more it’s worth, the more likely it is that the phrase is delivering business results for someone.
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.
Matt, my biggest complaint with Google and this “page Rank” nofollow nightmare is it seems we need to have a certain type of site to get ranked well or to make your crawler happy, you say you want a quality site, but what my users deem as quality (3000 links to the best academic information on the planet for business development) is actually looked at by Google as a bad thing and I do not get any rank because of it, makes it hard for my site to be found, and people that can really use the information can not find it when you yourself would look at the info and think it was fantastic to find it all in one place.
Get a link to your pages from an high PR page and yes, some of that PageRank importance is transmitted to your page. But that’s doesn’t take into account the context of the link — the words in the link — the anchor text. If you don’t understand anchor text, Google Now Reporting Anchor Text Phrases from me last month will take you by the hand and explain it more.
Muratos – I’ve never nofollowed Amazon affiliate links on the theory that search engines probably recognize them for what they are anyway. I have a blog, though, that gets organic traffic from those Amazon products simply because people are looking for “Copenhagen ring DVD” and I hard-code the product names, musicians’ names, etc. on the page rather than use Amazon’s sexier links in iframes, etc.
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.

Gaining Google's trust doesn't happen overnight. It takes time. Think about building up your relationship with anyone. The longer you know that person, the more likely that trust will solidify. So, the reasoning is, that if Google just met you, it's going to have a hard time trusting you. If you want Google to trust you, you have to get other people that Google already trusts, to vouch for you. This is also known as link-building.


SEO experts have a really bad habit: They like to throw around strange words and industry jargon when they talk to customers without checking to make sure that their clients understand the topic at hand. Some do this intentionally to paper over the fact that they use black hat techniques that will ultimately hurt their customers. But for most, it’s simply a matter of failing to recognize that part of their job is to educate their clients.


The course work of a marketing program will consist of real-world and hands-on components, such as case studies of both successful and failed marketing campaigns, and simulated businesses marketed by students using the concepts they have learned. This will include diving into several computer programs like Adobe InDesign and Dreamweaver, as well as both free and proprietary website analytics software.


Just do a quick Google search. If you're monitoring to see if a link you built is indexed, or just want to find other areas where you've been mentioned or linked, do a quick search with your company brand name, your web URL or other terms you're following. I've seen plenty of backlinks indexed by the search engine that never showed up in my search console account.
Online reviews, then, have become another form of internet marketing that small businesses can't afford to ignore. While many small businesses think that they can't do anything about online reviews, that's not true. Just by actively encouraging customers to post reviews about their experience small businesses can weight online reviews positively. Sixty-eight percent of consumers left a local business review when asked. So assuming a business's products or services are not subpar, unfair negative reviews will get buried by reviews by happier customers.
The flood of iframe and off-page hacks and plugins for WordPress and various other platforms might not come pouring in but I’m willing to bet the few that come in will begin to get prominence and popularity. It seemed such an easy way to keep control over PR flow offsite to websites you may not be ‘voting for’ and afterall, isn’t that way a link has always represented. It would seem Google should catch up with the times.

There’s no way to speed up the process. To encourage your PageRank to grow, keep making quality content that others will want to link to. You may also consider participating regularly in social media communities to get the word out about the new content you are creating. (Social media participation itself won’t help your PageRank but it will help other humans know your content exists, which can help inspire an increase in natural inbound linking.)
But this leads to a question — if my husband wants to do a roundup of every Wagner Ring Cycle on DVD, that’s about 8 Amazon links on the page, all bleeding PR away from his substantive insights. If he, instead, wants to do a roundup of every Ring Cycle on CD, that’s about two dozen items worth discussing. The page would be very handy for users, and would involve considerably more effort on his part… but no good deed goes unpunished, and in the eyes of Google the page would be devalued by more than two thirds.
Disney initially stated they wouldn’t exceed one million in donations, but ended up donating two million after the campaign blew up. #ShareYourEars campaign garnered 420 million social media impressions, and increased Make-A-Wish’s social media reach by 330%. The campaign is a powerful example of using an internet marketing strategy for a good cause. #ShareYourEars raised brand awareness, cultivated a connected online community, and positively affected Disney’s brand image.
Another illicit practice is to place "doorway" pages loaded with keywords on the client's site somewhere. The SEO promises this will make the page more relevant for more queries. This is inherently false since individual pages are rarely relevant for a wide range of keywords. More insidious, however, is that these doorway pages often contain hidden links to the SEO's other clients as well. Such doorway pages drain away the link popularity of a site and route it to the SEO and its other clients, which may include sites with unsavory or illegal content.
When an Internet user starts searching for something, he/she tries to solve some particular problem or achieve something. Your prior aim is to help them find a good solution. Don’t be obsessed with search volume only. Think about the user’s needs. There is no difference between 40,000 and 1,000 word posts and articles when we speak about their value. Try to create high-quality content and don’t pay any attention to certain stereotypes.
Assume a small universe of four web pages: A, B, C and D. Links from a page to itself, or multiple outbound links from one single page to another single page, are ignored. PageRank is initialized to the same value for all pages. In the original form of PageRank, the sum of PageRank over all pages was the total number of pages on the web at that time, so each page in this example would have an initial value of 1. However, later versions of PageRank, and the remainder of this section, assume a probability distribution between 0 and 1. Hence the initial value for each page in this example is 0.25.

PageRank is one of many, many factors used to produce search rankings. Highlighting PageRank in search results doesn’t help the searcher. That’s because Google uses another system to show the most important pages for a particular search you do. It lists them in order of importance for what you searched on. Adding PageRank scores to search results would just confuse people. They’d wonder why pages with lower scores were outranking higher scored pages.


PageRank has been used to rank spaces or streets to predict how many people (pedestrians or vehicles) come to the individual spaces or streets.[51][52] In lexical semantics it has been used to perform Word Sense Disambiguation,[53] Semantic similarity,[54] and also to automatically rank WordNet synsets according to how strongly they possess a given semantic property, such as positivity or negativity.[55]
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.
Mani, could not agree more your statements. It’s no wonder the SEO industry has such a bad name and it’s 99.9% Snake Oil. Still, Google, this Blog and other “SEO” sites are partly responsible for the PR hysteria, link spam and email spam for PR. Google should also put an end to Webmasters being screwed by SEO, but placing a BIG prominet statements on their Webmaster pages along the lines of;

The biggest problem that most people have when trying to learn anything to do with driving more traffic to their website or boosting their visibility across a variety of online mediums, is that they try to do the least amount of work for the greatest return. They cut corners and they take shortcuts. Because of that, they fail. Today, if you're serious about marketing anything on the web, you have to gain Google's trust.


SEO is a marketing discipline focused on growing visibility in organic (non-paid) search engine results. SEO encompasses both the technical and creative elements required to improve rankings, drive traffic, and increase awareness in search engines. There are many aspects to SEO, from the words on your page to the way other sites link to you on the web. Sometimes SEO is simply a matter of making sure your site is structured in a way that search engines understand.
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.
An Internet marketing campaign is not an isolated, one-off proposal. Any company that plans on using it once is certain to continue to use it. An individual who is knowledgeable about all aspects of an Internet marketing campaign and who has strong interpersonal skills is well-suited to maintain an ongoing managerial role on a dedicated marketing team.

PageRank as a visible score has been dying a slow death since around 2010, I’d say. Pulling it from the Google Toolbar makes it official, puts the final nail in the visible PageRank score coffin. The few actually viewing it within Internet Explorer, itself a depreciated browser, aren’t many. The real impact in dropping it from the toolbar means that third parties can no longer find ways to pull those scores automatically.
In this illustration from the “PageRank Citation Ranking” paper, the authors demonstrate how webpages pass value onto other pages. The two pages on the left have a value of 100 and 9, respectively. The page with a value of 100 has two links that point to the pages on the right. That page’s value of 100 is divided between the two links, so that each conveys a value of 50. The other page on the left has three outgoing links, each carrying one-third of the page’s value of 9. One link goes to the top page on the right, which ends up with a total value of 53. The bottom right page has no other backlinks, so its total value is 50.
This year, for the first time, Google stated that user experience would be a core part of gaining rankings for mobile websites. A poorer user experience would send your site hurtling down the rankings. This appeared to come as a shock to many in the SEO community and despite assurances that content was still king – many seemed to feel that this ...
I personally nofollow links to my privacy policy and contact form. Even though these are excluded in robots.txt, I prefer that extra layer of protection so that the pages are not indexed. Anyone that has ever had their contact form blasted continuously by spammers knows what I mean. And yes, one could add the noindex meta tag. But let’s face it, not everyone is a skilled PHP programmer. On dynamic sites its not as simple as adding a meta tag…

The internet was the little guy savior, simple sites could rank well locally. Sadly your company is in the process of destroying that. In this economy small business with zero page rank that are listed on page 22 of results, need to be found in order to survive. My customers are really suffering because of the work that is coming out of Google, it keeps getting worse. Their conversions are still good coming out of Yahoo and MSN and now Bing. They do not have the resources to produce blogs, forums, or $5,000 websites let alone pay for Adwords when they are just trying to pay rent and not a lot of people can do their own web production.

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.
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.

Getting unique and authoritative links is crucial for higher ranking in the SERPs and improving your SEO. Google's algorithm on evaluation of links evolved in recent years creating a more challenging process now to get high quality backlinks. External links still matter and aren’t obsolete, so start working on strategies to get valuable backlinks to improve your search visibility. 

Websites often employ SEO techniques to increase the number of backlinks pointing to their website. Some methods are free for use by everyone whereas some methods, like linkbaiting, require quite a bit of planning and marketing to work. There are also paid techniques to increase the number of backlinks to a target site. For example, private blog networks can be used to purchase backlinks.

Email marketing is the practice of nurturing leads and driving sales through email communications with your customers. Like social media, the goal is to remind users that you’re here and your product is waiting. Unlike social media, however, you can be a lot more aggressive with your sales techniques, as people expect that email marketing will contain offers, product announcements and calls to action.


The PageRank theory holds that an imaginary surfer who is randomly clicking on links will eventually stop clicking. The probability, at any step, that the person will continue is a damping factor d. Various studies have tested different damping factors, but it is generally assumed that the damping factor will be set around 0.85.[5] In applications of PageRank to biological data, a Bayesian analysis finds the optimal value of d to be 0.31.[24]
Unfortunately, SEO is also a slow process. You can make “quick wins” in markets which are ill-established using SEO, but the truth is that the vast majority of useful keyphrases (including long-tail keyphrases) in competitive markets will already have been optimized for. It is likely to take a significant amount of time to get to a useful place in search results for these phrases. In some cases, it may take months or even years of concentrated effort to win the battle for highly competitive keyphrases.
