where N is the total number of all pages on the web. The second version of the algorithm, indeed, does not differ fundamentally from the first one. Regarding the Random Surfer Model, the second version's PageRank of a page is the actual probability for a surfer reaching that page after clicking on many links. The PageRanks then form a probability distribution over web pages, so the sum of all pages' PageRanks will be one.

You can confer some of your site's reputation to another site when your site links to it. Sometimes users can take advantage of this by adding links to their own site in your comment sections or message boards. Or sometimes you might mention a site in a negative way and don't want to confer any of your reputation upon it. For example, imagine that you're writing a blog post on the topic of comment spamming and you want to call out a site that recently comment spammed your blog. You want to warn others of the site, so you include the link to it in your content; however, you certainly don't want to give the site some of your reputation from your link. This would be a good time to use nofollow.


Meanwhile, the link spam began. People chasing higher PageRank scores began dropping links wherever they could, including into blog posts and forums. Eventually, it became such an issue that demands were raised that Google itself should do something about it. Google did in 2005, getting behind the nofollow tag, a way to prevent links from passing along PageRank credit.
Halfdeck; Don’t you think the big problem is that Google is giving too much information to the industry? I stated a long time ago this fact, wondering why they wish to constantly hand out more information when they should have known the industry would try their best to exploit anyway. Not only that, but wanting more and more no matter how much Google hands out is something that is very clear as well. You just stated you want “more detail”. Why? I’m thinking too much detail handed out over the years is Google’s biggest problem right now. Considering the total majority of websites on the internet don’t know what a nofollow attribute is anyway, what exactly is Google gaining by giving up parts of their algo to the SEO industry? Big mistake. They should actually just shut up.
Google has a very large team of search quality raters that evaluate the quality of search results, that gets fed into a machine learning algorithm. Google’s search quality rater guidelines provide plenty of detail and examples of what Google class as high or low quality content and websites, and their emphasis on wanting to reward sites that clearly show their expertise, authority and trust (EAT).
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.
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.

SEO often involves the concerted effort of multiple departments within an organization, including the design, marketing, and content production teams. While some SEO work entails business analysis (e.g., comparing one’s content with competitors’), a sizeable part depends on the ranking algorithms of various search engines, which may change with time. Nevertheless, a rule of thumb is that websites and webpages with higher-quality content, more external referral links, and more user engagement will rank higher on an SERP.
Google can’t like this. Although its great for them to have spammers out of the Wikipedias, they’re also losing a lot of very authorative input for their PR algorithm. Think about it – if every site in the world put nofollow on every link Google’s algorithm would be worthless overnight. There has been ongoing speculation as to whether or not Google ignores nofollows from certain sites like Wikipedia, something Mr Cutts has outrightly denied (but also admitted that it would be very useful to have more granular control over nofollow so that it was not an all-or-nothing situation.)

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.
As Google becomes more and more sophisticated, one of the major cores of their algorithm, the one dealing with links (called Penguin) aims to value natural, quality links and devalue those unnatural or spammy ones. As a search engine, if they are to stay viable, they have to make sure their results are as honest and high-quality as possible, and that webmasters can't manipulate those results to their own benefit.
Social media has been one of the fastest growing digital marketing channels for years now and continues to play a major role in brand development and customer acquisition and engagement. Social media now is a critical element to effective content marketing and search engine optimization strategies. These marketing strategies simply can’t exist well without one another.
I segmented different verticals, did a Google search to see which website ranked #1 for that query (keep in mind that I performed this search using a VPN and not at the targeted location to get 'cleaner' results, so yours would be different, especially for local types of businesses), added it to my list, and then averaged out the percentages of link types (which I pulled from ahrefs.com). Click the link below to see my dataset.

Page rank is an assessment of the authority and value of a website in Google’s algorithm. You can find plug-in tools for your browser or online tools (see the references section for links to some of these) to check the page rank of any given site. You can also check your own website’s page rank. The higher the page rank, the more likely it is that your SEO efforts are succeeding.

Hi Brian thank you for sharing this awesome backlinking techniques. My site is currently not ranking well. It used to be, sometime mid last year, but it suddenly got de-ranked. Not really sure why. I haven’t been participating in any blackhat techniques or anything at all. I’ll try a few of your tips and hopefully it will help my site back to its shape.
While most of the links to your site will be added gradually, as people discover your content through search or other ways and link to it, Google understands that you'd like to let others know about the hard work you've put into your content. Effectively promoting your new content will lead to faster discovery by those who are interested in the same subject. As with most points covered in this document, taking these recommendations to an extreme could actually harm the reputation of your site.
A backlink’s value doesn’t only come from the website authority itself. There are other factors to consider as well. You’ll sometimes times hear those in the industry refer to “dofollow” and “nofollow” links. This goes back to the unethical linkbuilding tactics in the early days of SEO. One practices included commenting on blogs and leaving a link. It was an easy method and back then, search engines couldn’t tell the difference between a blog post and other site content.
I have to take my hat off to your content – not just for the tips you’ve given that have helped me with my websites, but for how clearly you can write. May I ask, what books or resources have inspired and influenced your writing and content creation the most? The two best books I’ve read so far to improve my writing are On Writing Well and Letting Go of the Words.

Early versions of search algorithms relied on webmaster-provided information such as the keyword meta tag or index files in engines like ALIWEB. Meta tags provide a guide to each page's content. Using metadata to index pages was found to be less than reliable, however, because the webmaster's choice of keywords in the meta tag could potentially be an inaccurate representation of the site's actual content. Inaccurate, incomplete, and inconsistent data in meta tags could and did cause pages to rank for irrelevant searches.[10][dubious – discuss] Web content providers also manipulated some attributes within the HTML source of a page in an attempt to rank well in search engines.[11] By 1997, search engine designers recognized that webmasters were making efforts to rank well in their search engine, and that some webmasters were even manipulating their rankings in search results by stuffing pages with excessive or irrelevant keywords. Early search engines, such as Altavista and Infoseek, adjusted their algorithms to prevent webmasters from manipulating rankings.[12]


A great number of people who deal with SEO confuse backlink building and backlink earning. These notions are different. What is backlink building? It means to create conditions for SEO backlink referring to your site. To earn a backlink means to deserve it. Is that really possible? Yes! If you want your site to be worth earning backlinks, you must do everything possible and impossible to please your guests and users.
Internet marketing, or online marketing, refers to advertising and marketing efforts that use the Web and email to drive direct sales via electronic commerce, in addition to sales leads from websites or emails. Internet marketing and online advertising efforts are typically used in conjunction with traditional types of advertising such as radio, television, newspapers and magazines.
A generalization of PageRank for the case of ranking two interacting groups of objects was described in [32] In applications it may be necessary to model systems having objects of two kinds where a weighted relation is defined on object pairs. This leads to considering bipartite graphs. For such graphs two related positive or nonnegative irreducible matrices corresponding to vertex partition sets can be defined. One can compute rankings of objects in both groups as eigenvectors corresponding to the maximal positive eigenvalues of these matrices. Normed eigenvectors exist and are unique by the Perron or Perron-Frobenius theorem. Example: consumers and products. The relation weight is the product consumption rate.
One of the consequences of the PageRank algorithm and its further manipulation has been the situation when backlinks (as well as link-building) have been usually considered black-hat SEO. Thus, not only Google has been combating the consequences of its own child's tricks, but also mega-sites, like Wikipedia, The Next Web, Forbes, and many others who automatically nofollow all the outgoing links. It means fewer and fewer PageRank votes. What is then going to help search engines rank pages in terms of their safety and relevance?
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.

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.
As of 2009, there are only a few large markets where Google is not the leading search engine. In most cases, when Google is not leading in a given market, it is lagging behind a local player. The most notable example markets are China, Japan, South Korea, Russia and the Czech Republic where respectively Baidu, Yahoo! Japan, Naver, Yandex and Seznam are market leaders.
PageRank sculpting came out of the idea that virtually any page will have links that are important for users but not necessarily that meaningful to receive any PageRank that a page can flow. Navigational links are a primary example of this. Go to a place like the LA Times, and you’ve got tons of navigational links on every page. Nofollow those, and you (supposedly in the past) ensure that the remaining links (say your major stories) get more of a boost.
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 …
I started taking action right away on the “Best Of” Blog Posts” approach… I found some great blogs and left a relevant and useful comment. The first impression, sins a lot of the blogs see my as the competition it is not easy to get past the moderator. I made 6 or 7 comments the first day and will update this comment after I have a good number of post to measure results…
It’s important to monitor the backlinks your site is accumulating. First, you can verify that your outreach is working. Second, you can monitor if you pick up any shady backlinks. Domains from Russia and Brazil are notorious origins of spam. Therefore, it can be wise to disavow links from sites originating from this part of the world through Google Search Console as soon as you find them – even if they haven’t impacted your site… yet.
People think about PageRank in lots of different ways. People have compared PageRank to a “random surfer” model in which PageRank is the probability that a random surfer clicking on links lands on a page. Other people think of the web as an link matrix in which the value at position (i,j) indicates the presence of links from page i to page j. In that case, PageRank corresponds to the principal eigenvector of that normalized link matrix.

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.


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.
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. 

As digital marketing continues to grow and develop, brands take great advantage of using technology and the Internet as a successful way to communicate with its clients and allows them to increase the reach of who they can interact with and how they go about doing so,.[2] There are however disadvantages that are not commonly looked into due to how much a business relies on it. It is important for marketers to take into consideration both advantages and disadvantages of digital marketing when considering their marketing strategy and business goals.

As an example, people could previously create many message-board posts with links to their website to artificially inflate their PageRank. With the nofollow value, message-board administrators can modify their code to automatically insert "rel='nofollow'" to all hyperlinks in posts, thus preventing PageRank from being affected by those particular posts. This method of avoidance, however, also has various drawbacks, such as reducing the link value of legitimate comments. (See: Spam in blogs#nofollow)
Still, before we get there, there's a whole lot of information to grasp. As an online marketer myself, it's important that I convey the truth about the industry to you so that you don't get sucked up into the dream. While there are legitimate marketers like Sharpe out there ready and willing to help, there are loads of others that are simply looking to help part you from your hard-earned cash. Before you do anything, gather all of the information you can.
However, with all of these so-called modern conveniences to life, where technology's ever-pervading presence has improved even the most basic tasks for us such as hailing a ride or ordering food or conducting any sort of commerce instantly and efficiently, many are left in the dark. While all of us have become self-professed experts at consuming content and utilizing a variety of tools freely available to search and seek out information, we're effectively drowning in a sea of digital overload.
The Truth? You don't often come across genuine individuals in this space. I could likely count on one hand who those genuine-minded marketers might be. Someone like Russel Brunson who's developed a career out of providing true value in the field and helping to educate the uneducated is one such name. However, while Brunson has built a colossal business, the story of David Sharpe and his journey to becoming an 8-figure earner really hits home for most people.
If you’re a blogger (or a blog reader), you’re painfully familiar with people who try to raise their own websites’ search engine rankings by submitting linked blog comments like “Visit my discount pharmaceuticals site.” This is called comment spam, we don’t like it either, and we’ve been testing a new tag that blocks it. From now on, when Google sees the attribute (rel=“nofollow”) on hyperlinks, those links won’t get any credit when we rank websites in our search results.
Links still matter as part of the algorithmic secret sauce. The influence of a site’s link profile is plain to see in its search engine rankings, whether for better or worse, and changes in that link profile cause noticeable movement up or down the SERP. An SEO’s emphasis today should be on attracting links to quality content naturally, not building them en masse. (For more on proper link building today, see http://bit.ly/1XIm3vf )
Finally, start building links in relevant sites like business directories (especially local directories) relevant niche blogs and forums, and industry publications. Success at link building will result from a combination of good PR, smart marketing strategy, and of course, great content. Google has said that social media doesn’t impact rankings, but reaching out to social influencers can give your content traction on other channels that can be useful.
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]
Companies often use email marketing to re-engage past customers, but a “Where’d You Go? Want To Buy This?” message can come across as aggressive, and you want to be careful with your wording to cultivate a long-term email subscriber. This is why JetBlue’s one year re-engagement email works so well -- it uses humor to convey a sense of friendliness and fun, while simultaneously reminding an old email subscriber they might want to check out some of JetBlue’s new flight deals.
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.
But I also don’t wanna lose PageRank on every comment with a link… If I can give PageRank and lose none, I wanna let the comment there, even without nofollow. But if I lose PageRank on every link, even inside original post, EVEN MORE if nofollow also takes PageRank out of me, I may just start using JavaScript or simple text without anchor for links… I definetely don’t like this idea, but I dislike even more losing PageRank on each outlink on my site. I’d just link top quality sites that I actively wanna vote for Search Engines.
While ordinary users were not that interested in pages' scores, SEOs of a different caliber felt that this was a great opportunity to make a difference for their customers. This obsession of SEOs with PageRank made everyone feel that this ranking signal is more or less the only important one. In spite of the fact that pages with a lower PR score can beat those with a higher score! What did we receive then, as a result?
