There are simple and fast random walk-based distributed algorithms for computing PageRank of nodes in a network.[33] They present a simple algorithm that takes {\displaystyle O(\log n/\epsilon )} rounds with high probability on any graph (directed or undirected), where n is the network size and {\displaystyle \epsilon } is the reset probability ( {\displaystyle 1-\epsilon } is also called as damping factor) used in the PageRank computation. They also present a faster algorithm that takes {\displaystyle O({\sqrt {\log n}}/\epsilon )} rounds in undirected graphs. Both of the above algorithms are scalable, as each node processes and sends only small (polylogarithmic in n, the network size) number of bits per round.
Link text is the visible text inside a link. This text tells users and Google something about the page you're linking to. Links on your page may be internal—pointing to other pages on your site—or external—leading to content on other sites. In either of these cases, the better your anchor text is, the easier it is for users to navigate and for Google to understand what the page you're linking to is about.

Let’s start with what Google says. In a nutshell, it considers links to be like votes. In addition, it considers that some votes are more important than others. PageRank is Google’s system of counting link votes and determining which pages are most important based on them. These scores are then used along with many other things to determine if a page will rank well in a search.
Also, I’ve never found that page rank scultping worked. It might have for smaller sites that have a simple structure to follow. but in case of CMS’s handling a large number of pages and dynamic websites, its not practical to have an intricate graph of how your page rank flows. I mean, even if you did, wouldn’t it be easy and clever if you just leave some thumb rules (like always nofollowing an external link) and leave it to Google for the rest ? Rather ocus on the content ?

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.)
All of the examples above and more could be used as anchor text for the same backlink. Google will index each differently. Not only that, Google will even examine the few words before and after the anchor text as well as take into account all of the text on the page. It will also attribute value to which backlink was first in the page and diminish the value for each following link.
I liken this to a paradoxical Catch-22 scenario, because it seems like without one you can't have the other. It takes money to drive traffic, but it takes traffic to make money. So don't make the mistake that millions of other online marketers make around the world. Before you attempt to scale or send any semblance of traffic to your offers, be sure to split-test things to oblivion and determine your conversion rates before diving in headfirst.
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.

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.
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.
According to the U.S. Commerce Department, consumers spent $453.46 billion on the web for retail purchases in 2017, a 16.0% increase compared with $390.99 billion in 2016. That’s the highest growth rate since 2011, when online sales grew 17.5% over 2010. Forrester predicts that online sales will account for 17% of all US retail sales by 2022. And digital advertising is also growing strongly; According to Strategy Analytics, in 2017 digital advertising was up 12%, accounting for approximately 38% of overall spending on advertising, or $207.44 billion.
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!)
Suggesting that this change is really just the equivalent of “resetting” things to the way they were is absurd. nofollow is still be using on outbound links in mass by the most authoritative/trusted sites on the web. Allowing us peons to have a slight bit of control over our internal juice flow simply allowed us to recoup a small portion of the overall juice that we lost when the top-down flow was so dramatically disrupted.
3) Some people don’t believe things have changed. In fact, if things really changed substantially a year ago, you’d think a few of the advanced SEOs out there would have noticed this and talked about it. But nada. There are lots of reasons why the change could have happened and not been spotted. Sculpting might really have been a second or third order factor, as Matt calls it — not helping things as much as some have assumed. SEOs that spotted it might have stayed quiet. Or, it didn’t change — and still hasn’t changed — and sculpting does work even better than Google thought, so it wants to put out a message that it doesn’t, in hopes of putting the genie back in the bottle. That’s probably the major conspiracy theory out there.
Most people need to take a step back and understand where money is even coming from on the web. Sharpe says that, when asked, most individuals don't actually even know how money is being made on a high level. How does Facebook generate its revenues? How about Google? How do high-trafficked blogs become so popular and how do they generate money from all of that traffic? Is there one way or many?

Danny, I was on the panel where Matt suggested that and I point blank asked on stage what happened when folks starting abusing the tactic and Google changed their mind if you recall (at the time, I’d seen some of the things being done I knew Google would clarify as abuse and was still a nofollow unenthusiast s a result at that time). And Matt dismissed it. So, I think you can take home two important things from that – 1. SEO tactics can always change regardless of who first endorses them and 2. Not everything Matt says is etched in stone. <3 ya Matt.

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:


Online competition is fiercer than ever—and if you want to create a website that outperforms industry benchmarks in a big way, it’s vital that you know how to utilize your design skills to keep users engaged. The more engaged users are, the more likely they are to turn into paying customers—people who will buy your products and services time and time again, remain loyal, and ultimately become ambassadors for your brand both on- and offline.

It doesn’t mean than you have to advertise on these social media platforms. It means that they belong to that pyramid which will function better thanks to their support. Just secure them and decide which of them will suit your goal better. For example, you can choose Instagram because its audience is the most suitable for mobile devices and bits of advice of their exploitation distribution.
Going into network marketing? Understand that if you're not close to the top of the food chain there, your ability to generate any serious amount of income will be limited. Be wary of the hype and the sales pitches that get you thinking that it's going to work the other way. Simply understand that you're going to have to work hard no matter what you pick to do. Email marketing? Sure. You can do that. But you'll need a massive and very targeted list to make any dent.

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.
According to the U.S. Commerce Department, consumers spent $453.46 billion on the web for retail purchases in 2017, a 16.0% increase compared with $390.99 billion in 2016.

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.

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.
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 🙂
Numerous academic papers concerning PageRank have been published since Page and Brin's original paper.[5] In practice, the PageRank concept may be vulnerable to manipulation. Research has been conducted into identifying falsely influenced PageRank rankings. The goal is to find an effective means of ignoring links from documents with falsely influenced PageRank.[6]
Infographics are one of the most popular methods for bringing traffic to your website and gaining valuable backlinks. They're also great because they're easy to understand and share. Everyone loves visual data, right? That's why the demand for infographics has increased considerably. Consider that influential online publications like Mashable publish numerous infographics from all over the Internet.

Display advertising - As the term infers, Online Display Advertisement deals with showcasing promotional messages or ideas to the consumer on the internet. This includes a wide range of advertisements like advertising blogs, networks, interstitial ads, contextual data, ads on the search engines, classified or dynamic advertisement etc. The method can target specific audience tuning in from different types of locals to view a particular advertisement, the variations can be found as the most productive element of this method.


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.
By now, you've likely seen all the "gurus" in your Facebook feed. Some of them are more popular than others. What you'll notice is that the ads you see that have the highest views and engagement are normally the most successful. Use a site like Similar Web to study those ads and see what they're doing. Join their lists and embed yourself in their funnels. That's an important part of the process so that you can replicate and reverse engineer what the most successful marketers are doing.

The new digital era has enabled brands to selectively target their customers that may potentially be interested in their brand or based on previous browsing interests. Businesses can now use social media to select the age range, location, gender and interests of whom they would like their targeted post to be seen by. Furthermore, based on a customer's recent search history they can be ‘followed’ on the internet so they see advertisements from similar brands, products and services,[38] This allows businesses to target the specific customers that they know and feel will most benefit from their product or service, something that had limited capabilities up until the digital era.
A way to build backlinks by providing value to other sites is through branded badges. A branded badge is an award that a brand creates and gives out to other sites as a status symbol. For example, you could create a list of the top sites or best brands that are published on your site, and then give badges to each brand on the list so that they can show the status on their site. You include a link back to the article on the badge to create the link.
On October 17, 2002, SearchKing filed suit in the United States District Court, Western District of Oklahoma, against the search engine Google. SearchKing's claim was that Google's tactics to prevent spamdexing constituted a tortious interference with contractual relations. On May 27, 2003, the court granted Google's motion to dismiss the complaint because SearchKing "failed to state a claim upon which relief may be granted."[67][68]
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.
Discoverability is not a new concept for web designers. In fact Search Engine Optimization and various forms of Search Engine Marketing arose from the need to make websites easy to discover by users. In the mobile application space this issue of discoverability is becoming ever more important – with nearly 700 apps a day being released on Apple’...
But, why do search engines care about backlinks? Well, in the early days of the Internet, search engines were very simple, and relied strictly on keyword matching. It didn’t matter how good the content on a website was, how popular it was, or what the website was for–if a phrase on a page matched a phrase that someone searched for, then that page would likely show up. That meant that if someone had an online journal in which they documented at length how they had to take their car to a “car accident repair shop,” then people searching for a “car accident repair shop” would likely be led to that page. Not terribly useful, right?
An entrepreneur or freelancer has two main strategies to tap into when marketing online. Search Engine Optimization (SEO), which attempts to rank your website on search engines “organically”, and Search Engine Marketing (SEM), which ranks your website in search results in exchange for money. Both strategies can be used to build a business succes...
On the other hand, all of the results for the PageRank engine (aside from a single secondary listing) link to the homepage of major American universities. The results are much more logical and useful in nature. If you search for “university,” are you going to want the homepages for popular universities, or random subpages from a sprinkling of colleges all over the world?
If you really want everyone to forget about sculpting, then either ditch support for nofollow completely, or at a bare minimum, implement some type of real filter that demotes sites with excessive levels of external nofollows. The idea that the sculpting mom & pop struggling to compete is somehow a spammer, yet sites like the wiki are algorithmically rewarded for systematically cutting off the flow of juices to thousands of sites that are in no way close to the kind of sites nofollow was developed to combat, is simply insane.

Another disadvantage is that even an individual or small group of people can harm image of an established brand. For instance Dopplegnager is a term that is used to disapprove an image about a certain brand that is spread by anti-brand activists, bloggers, and opinion leaders. The word Doppelganger is a combination of two German words Doppel (double) and Ganger (walker), thus it means double walker or as in English it is said alter ego. Generally brand creates images for itself to emotionally appeal to their customers. However some would disagree with this image and make alterations to this image and present in funny or cynical way, hence distorting the brand image, hence creating a Doppelganger image, blog or content (Rindfleisch, 2016).
Video advertising - This type of advertising in terms of digital/online means are advertisements that play on online videos e.g. YouTube videos. This type of marketing has seen an increase in popularity over time.[50] Online Video Advertising usually consists of three types: Pre-Roll advertisements which play before the video is watched, Mid-Roll advertisements which play during the video, or Post-Roll advertisements which play after the video is watched.[51] Post-roll advertisements were shown to have better brand recognition in relation to the other types, where-as "ad-context congruity/incongruity plays an important role in reinforcing ad memorability".[50] Due to selective attention from viewers, there is the likelihood that the message may not be received.[52] The main advantage of video advertising is that it disrupts the viewing experience of the video and therefore there is a difficulty in attempting to avoid them. How a consumer interacts with online video advertising can come down to three stages: Pre attention, attention, and behavioural decision.[53] These online advertisements give the brand/business options and choices. These consist of length, position, adjacent video content which all directly affect the effectiveness of the produced advertisement time,[50] therefore manipulating these variables will yield different results. Length of the advertisement has shown to affect memorability where-as longer duration resulted in increased brand recognition.[50] This type of advertising, due to its nature of interruption of the viewer, it is likely that the consumer may feel as if their experience is being interrupted or invaded, creating negative perception of the brand.[50] These advertisements are also available to be shared by the viewers, adding to the attractiveness of this platform. Sharing these videos can be equated to the online version of word by mouth marketing, extending number of people reached.[54] Sharing videos creates six different outcomes: these being "pleasure, affection, inclusion, escape, relaxation, and control".[50] As well, videos that have entertainment value are more likely to be shared, yet pleasure is the strongest motivator to pass videos on. Creating a ‘viral’ trend from mass amount of a brands advertisement can maximize the outcome of an online video advert whether it be positive or a negative outcome.
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…
Hi Bill, Yes – thanks. I think I’ll have to do more of these. I couldn’t really go beyond Pagerank in an 18 minute Pubcon session. Although the random surfer model expired (and wasn’t even assigned to Google), it is still a precursor to understanding everything that has come after it. I think I would love to do more videos/presentations on both Reasonable surfer patent, Dangling Nodes and probably a lifetime of other videos in the future. To be able to demonstrate these concept without giving people headaches, though, the PageRank algorithm in Matrix form provides a good understanding of why you can’t "just get links" and expect everything to be at number 1.
In the page, the text “Post Modern Marketing” is a link that points to the homepage of our website, www.postmm.com. That link is an outgoing link for Forbes, but for our website it is an incoming link, or backlink. Usually, the links are styled differently than the rest of the page text, for easy identification. Often they'll be a different color, underlined, or accompany an icon - all these indicate that if you click, you can visit the page the text is referencing.
Marketing managers need to be conversant in every element of a marketing campaign, and considering the importance of an Internet presence in any marketing plan today, this means having a clear understanding of Internet marketing from start to finish. A marketing manager should have confidence in his or her team and know how to facilitate work efficiency and communication between coworkers. This keeps each project on schedule and helps create a relaxed work environment.
Something a lot of people seem to have overlooked was hinted at in Greg Boser’s comment above. Greg identified that there is a major (and unfair) disparity with how authority sites such as Wikipedia disrupt the linkscape by run-of-site nofollows. Once Wikipedia implemented the no-follows, previously high-value links from Wikipedia were rendered worthless making the site less of a target for spammers. Increasingly large sites are following suit in order to cleanse their own pages of spam.
All in all, PageRank sculpting (or whatever we should call it) didn’t really rule my world. But, I did think that it was a totally legitimate method to use. Now that we know the ‘weight’ leaks, this will put a totally new (and more damaging) spin on things. Could we not have just left the ‘weight’ with the parent page? This is what I thought would happen most of the time anyway.
The paper’s authors noted that AltaVista (on the right) returned a rather random assortment of search results–rather obscure optical physics department of the University of Oregon, the campus networking group at Carnegie Mellon, Wesleyan’s computer science group, and then a page for one of the campuses of a Japanese university. Interestingly, none of the first six results return the homepage of a website

When you comment on a blog post, you are usually allowed to include a link back to your website. This is often abused by spammers and can become a negative link building tool. But if you post genuine comments on high-quality blog posts, there can be some value in sharing links, as it can drive traffic to your site and increase the visibility of your brand.


Backlinks are important for a number of reasons. The quality and quantity of pages backlinking to your website are some of the criteria used by search engines like Google to determine your ranking on their search engine results pages (SERP). The higher you rank on a SERP, the better for your business as people tend to click on the first few search results Google, Bing or other search engines return for them.
Advanced link analysis includes differentiating between sections of pages and treating links differently. What makes you think G or other engines treat links in the editorial section and comments section of the webpages the same as each other. Especially for those content management systems that are widely in use like wordpress, joomla, etc. The advice here is helpful and has nothing to do with creating a nightmare. All those who are asking questions here and envision a nightmare would agree that links in the footer section are treated differently. How is that possible if sections on a page are not classified and treated differently.

Some backlinks are inherently more valuable than others. Followed backlinks from trustworthy, popular, high-authority sites are considered the most desirable backlinks to earn, while backlinks from low-authority, potentially spammy sites are typically at the other end of the spectrum. Whether or not a link is followed (i.e. whether a site owner specifically instructs search engines to pass, or not pass, link equity) is certainly relevant, but don't entirely discount the value of nofollow links. Even just being mentioned on high-quality websites can give your brand a boost.


Many webmasters have more than one website. Sometimes these websites are related, sometimes they are not. You have to also be careful about interlinking multiple websites on the same IP. If you own seven related websites, then a link to each of those websites on a page could hurt you, as it may look like to a search engine that you are trying to do something fishy. Many webmasters have tried to manipulate backlinks in this way; and too many links to sites with the same IP address is referred to as backlink bombing.
By utilizing SEM, it provides you with a great avenue for getting the word out quickly and effectively. If you have the budget, then marketing on search engines for competitive keywords might be the right fit for you. But be prepared to pony up. Keywords can range anywhere from a few cents to upwards of $50 and more. The quality score for any term is reflective of what you can expect to pay for bidding on that keyword. The lower the competition, the lower the quality score and the lower the price.
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.
Thanks for the post Chelsea! I think Google is starting to move further away from PageRank but I do agree that a higher amoount of links doesn’t necessarily mean a higher rank. I’ve seen many try to shortcut the system and end up spending weeks undoing these “shortcuts.” I wonder how much weight PageRank still holds today, considering the algorithms Google continues to put out there to provide more relevant search results.
Danny, I was on the panel where Matt suggested that and I point blank asked on stage what happened when folks starting abusing the tactic and Google changed their mind if you recall (at the time, I’d seen some of the things being done I knew Google would clarify as abuse and was still a nofollow unenthusiast s a result at that time).

Not everything Matt says is etched in stone. <3 ya Matt.

Just secure them and decide which of them will suit your goal better. For example, you can choose Instagram because its audience is the most suitable for mobile devices and bits of advice of their exploitation distribution.
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.

Site owners are using the toolbar to find “good” sites that they should get links from, regardless of the fact that link context is also important, not to mention many, many other factors that are used by Google to rank a web page. Other site owners, getting a gray PR0 toolbar for their site, immediate assume the worst, that they’ve been blacklisted.
