As mentioned above, the two versions of the algorithm do not differ fundamentally from each other. A PageRank which has been calculated by using the second version of the algorithm has to be multiplied by the total number of web pages to get the according PageRank that would have been caculated by using the first version. Even Page and Brin mixed up the two algorithm versions in their most popular paper "The Anatomy of a Large-Scale Hypertextual Web Search Engine", where they claim the first version of the algorithm to form a probability distribution over web pages with the sum of all pages' PageRanks being one.

Changes to the algorithms that produce search engine rankings can place a heightened focus on relevance to a particular topic. While some backlinks might be from sources containing highly valuable metrics, they could also be unrelated to the consumer's query or interest. An example of this would be a link from a popular shoe blog (with valuable metrics) to a site selling vintage pencil sharpeners. While the link appears valuable, it provides little to the consumer in terms of relevance.


Digital marketing planning is a term used in marketing management. It describes the first stage of forming a digital marketing strategy for the wider digital marketing system. The difference between digital and traditional marketing planning is that it uses digitally based communication tools and technology such as Social, Web, Mobile, Scannable Surface.[57][58] Nevertheless, both are aligned with the vision, the mission of the company and the overarching business strategy.[59]

Email marketing - Email marketing in comparison to other forms of digital marketing is considered cheap; it is also a way to rapidly communicate a message such as their value proposition to existing or potential customers. Yet this channel of communication may be perceived by recipients to be bothersome and irritating especially to new or potential customers, therefore the success of email marketing is reliant on the language and visual appeal applied. In terms of visual appeal, there are indications that using graphics/visuals that are relevant to the message which is attempting to be sent, yet less visual graphics to be applied with initial emails are more effective in-turn creating a relatively personal feel to the email. In terms of language, the style is the main factor in determining how captivating the email is. Using casual tone invokes a warmer and gentle and inviting feel to the email in comparison to a formal style. For combinations; it's suggested that to maximize effectiveness; using no graphics/visual alongside casual language. In contrast using no visual appeal and a formal language style is seen as the least effective method.[48]

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. 

Thanks Matt for the informative post. However I do have some questions regarding blog comments. Let say a blog post of mine have PR 10, the page has 10 links, 3 of them are my internal link to my other related post, the other 7 links are external links from blog comment. Based on your explanation, even the 7 external links are nofollow, my 3 internal link will only get 1 PR each which is still the same if the 7 external link is dofollow. Therefore there is no point of adding nofollow for the sake of keeping the PR flow within your own links. Is this correct?
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.
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.
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.

A decent article which encourages discussion and healthy debate. Reading some of the comments I see it also highlights some of the misunderstandings some people (including some SEOs) have of Google PageRank. Toolbar PageRank is not the same thing as PageRank. The little green bar (Toolbar PageRank) was never a very accurate metric and told you very little about the value of any particular web page. It may have been officially killed off earlier this year, but the truth is its been dead for many years. Real PageRank on the other hand, is at the core of Google’s algorithm and remains very important.

I really hope that folks don’t take the idea of disabling comments to heart… first that isn’t much fun for you the blog owner or your visitors. Second… I just did a cursory glance at the SERPS for ‘pagerank sculpting’ (how I found this post). Interestingly enough, the number of comments almost has a direct correlation with the ranking of the URL. I’m not so certain that there is a causal relationship there. But I would certainly consider that Google probably has figured out how to count comments on a WP blog and probably factors that into ranking. I know that I would.

Pagerank has recently been used to quantify the scientific impact of researchers. The underlying citation and collaboration networks are used in conjunction with pagerank algorithm in order to come up with a ranking system for individual publications which propagates to individual authors. The new index known as pagerank-index (Pi) is demonstrated to be fairer compared to h-index in the context of many drawbacks exhibited by h-index.[63]
(spread across a number of pages) which lists something like 1,000 restaurants in a large city with contact details and a web link to each of those restaurant’s home page. Given that the outgoing links are relevant to my content, should I or should I not be using REL=nofollow for each link given the massive quantity of them? How will my ranking for pages containing those links and pages elsewhere on my site be affected if I do or don’t include REL=nofollow for those links? My fear is that if I don’t use REL=nofollow, Google will assume my site is just a generic directory of links (given the large number of them) and will penalize me accordingly.

So be wary. Ensure that you learn from the pros and don't get sucked into every offer that you see. Follow the reputable people online. It's easy to distinguish those that fill you with hype and those that are actually out there for your benefit. Look to add value along the way and you'll succeed. You might find it frustrating at the outset. Everyone does. But massive amounts of income await those that stick it out and see things through.
4. The facets of content marketing. Though content marketing can be treated as a distinct strategy, I see it as a necessary element of the SEO process. Only by developing high-quality content over time will you be able to optimize for your target keywords, build your site’s authority, and curate a loyal recurring audience. You should know the basics, at the very least, before proceeding with other components of SEO.

Less than 2 years ago one could promote a website within a month with the help of PBN (Private Blog Network). Then Google created “a sandbox” which made a site owner wait no less than 3 months before the effect of PBN backlinks turned to be visible. There are two more negative factors: risk and financial investment. You will realize that neither your wasted time nor money were worth it. That’s why it’s better to rely on proper backlinks from real sites.
So, now we're getting to backlinks that have relatively little, or even negative value. The value of web directories has diminished dramatically in recent years. This shouldn't come as a surprise. After all, when was the last time that you used a web directory to find anything, rather than just doing a Google search? Google recognizes that directories don't have any real world worth, and so they don't accord much value to backlinks on them. But there is an exception to this rule. Submitting your website to local, industry-specific and niche directories can net you worthwhile backlinks. But if you can't imagine a circumstance where someone would use a certain directory, then it's probably not worth your time.
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.
By the way, YouTube currently is all over the place. It nofollows links in the Spotlight and Featured areas, where you assume there’s some editorial oversight. But since some of these show on the basis of a commercial relationship, maybe YouTube is being safe. Meanwhile, Videos Being Watched now which is kind of random isn’t blocked — pretty much the entire page is no longer blocked.
However, if you are seasoned online marketer, and you've built a substantial following, then marketing as an affiliate might be the right fit. Jason Stone from Millionaire Mentor has built a seven-figure business with affiliate marketing, while David Sharpe from Legendary Marketer has built up an eight-figure business by creating an army of affiliates that market products in collaboration with his team.
When writing this guide, we reached out to the marketer community to collect case studies and learnings about creative marketing strategies. Most of these examples are included throughout the guide, but some didn’t quite fit. So we included those loose ends here, from the perspective of four awesome marketers. What better way to wrap up this guide than with you, our community?

My favorite style in this is article marketing. You create anchor content on your website or blog, then you build authority-content links to that content, effectively driving up the visibility. I've used this single strategy to rank hundreds of keywords in the #1 spot on Google, and I would highly recommend that if you're going to learn any marketing strategy, that you get really good at this one.
I am not worried by this; I do agree with Danny Sullivan (Great comment Danny, best comment I have read in a long time). I will not be changing much on my site re: linking but it is interesting too see that Google took over a year to tell us regarding the change, but was really happy to tell us about rel=”nofollow” in the first place and advised us all to use it.
First and foremost, when it comes to marketing anything online, it's important to understand how money is made and earned. In my phone call with Sharpe, he identified several items that were well worth mentioning. Once you understand where the money comes from and how the industry works, you can then better understand how best to position yourself and your offer so that you can reap the benefits of the making-money-while-you-sleep industry.

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)
Sharpe, who's presently running a company called Legendary Marketer, teaching you how to duplicate his results, is a prime example. By understanding how Sharpe has constructed his value chain, positioned his offerings and built out his multi-modality sales funnels, you'll better get a larger grasp on things. As confusing as it sounds at the outset, all you need to do is start buying up products in your niche so that you can replicate their success.
Understand that whatever you're going to do, you'll need traffic. If you don't have any money at the outset, your hands will be tied no matter what anyone tells you. The truth is that you need to drive traffic to your offers if you want them to convert. These are what we call landing pages or squeeze pages. This is where you're coming into contact with the customers, either for the first time or after they get to know you a little bit better.
