The mathematics of PageRank are entirely general and apply to any graph or network in any domain. Thus, PageRank is now regularly used in bibliometrics, social and information network analysis, and for link prediction and recommendation. It's even used for systems analysis of road networks, as well as biology, chemistry, neuroscience, and physics.[45]
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?
A great number of public networks call themselves “private”. That’s not true. If the network is advertised, it cannot be private. We witnessed cases when Google destroyed such public networks and all the websites which had used them. They are easy to be revealed due to a huge number of outbound homepage links which are irrelevant to each other. Their posts are short, and they cannot really block SEO crawlers.

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.
Disclaimer: 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. I’ll do the rest of my blog post in the framework of “classic PageRank” but bear in mind that it’s not a perfect analogy.

Bob Dole (interesting name), you’re certainly welcome to use Bing if you prefer, but before you switch, you might check whether they do similar things. I know that Nate Buggia has strongly recommended not to bother with PageRank sculpting in the past, for example, or at least that was my perception from his comments at the last couple SMX Advanced conferences.
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.
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.
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.

You want better PageRank? Then you want links, and so the link-selling economy emerged. Networks developed so that people could buy links and improve their PageRank scores, in turn potentially improving their ability to rank on Google for different terms. Google had positioned links as votes cast by the “democratic nature of the web.” Link networks were the Super PACs of this election, where money could influence those votes.
Before I start this, I am using the term ‘PageRank’ as a general term fully knowing that this is not a simple issue and ‘PageRank’ and the way it is calculated (and the other numerous methods Google use) are multidimensional and complex. However, if you use PageRank to imply ‘weight’ it make it a lot simpler. Also, ‘PageRank sculpting’ (in my view) is meant to mean ‘passing weight you can control’. Now… on with the comment!
We must be careful with our reciprocal links. There is a Google patent in the works that will deal with not only the popularity of the sites being linked to, but also how trustworthy a site is that you link to from your own website. This will mean that you could get into trouble with the search engine just for linking to a bad apple. We could begin preparing for this future change in the search engine algorithm by being choosier with which we exchange links right now. By choosing only relevant sites to link with, and sites that don't have tons of outbound links on a page, or sites that don't practice black-hat SEO techniques, we will have a better chance that our reciprocal links won't be discounted.
There’s a misconception that creating an infographic is expensive; that's not always the case. Figure on an average price between $150 and $300. Assuming you may earn 10 backlinks per infographic, you'll be paying $15 per link. For five backlinks, the price will be $30 per link. That’s very cheap for backlinks earned through webmaster moderation. And if your infographic goes viral. you win even more.

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.

Matt, as you know, I was kind of annoyed when you suggested sculpting to a room full of SEOs back in 2007. We’d been told over the years to do things for humans, not to overly worry about having to do stuff for search engines — and suddenly, here you were suggesting that SEOs could flow PageRank to their most “important” pages. I’d figured Google had long since been smart enough to decide for itself what percentage of a page’s PageRank spend to assign to a particular link. That assumption didn’t just come out of the blue — it came from things Google had hinted at over the years. So being told to start overtly flowing around the PageRank? It seemed counter-productive.
How does it work? In essence, you use Google Adwords (or another search engine’s equivalent – depending on the market you work in; in China, you’d be looking at Baidu, for example) to place bids on keyphrases; you write an advert based on that keyphrase; the search engine places the advert near the top of the search rankings, and you pay the amount of the bid every time someone clicks on your advert.

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]
Word of mouth communications and peer-to-peer dialogue often have a greater effect on customers, since they are not sent directly from the company and are therefore not planned. Customers are more likely to trust other customers’ experiences.[22] Examples can be that social media users share food products and meal experiences highlighting certain brands and franchises. This was noted in a study on Instagram, where researchers observed that adolescent Instagram users' posted images of food-related experiences within their social networks, providing free advertising for the products.[26]

I just did a consult and opinion letter for an extremely large 200,000+ page corporate website that had been forced to temporarily remove their html sitemap due to some compromised code that overloaded their server and crashed the site. A number of individuals at the company were concerned at the potential, negative SEO implications of removing this page, loss of page rank equity transfer to sitemap targets and a feeling that this page was providing the robots with important pathways to many of the orphan pages unavailable through the menu system. This article was helpful in debunking the feeling that a page with 200,000 links off of it was passing any link juice to the targets. PS. XML sitemap in place.

PageRank was developed by Google founders Larry Page and Sergey Brin at Stanford. In fact the name. PageRank is a likely play on Larry Page's name. At the time that Page and Brin met, early search engines typically linked to pages that had the highest keyword density, which meant people could game the system by repeating the same phrase over and over to attract higher search page results. Sometimes web designers would even put hidden text on pages to repeat phrases. 
In the page, the text “Post Modern Marketing” is a link that points to the homepage of our website, 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.
There's a lot to learn when it comes to the internet marketing field in general, and the digital ether of the web is a crowded space filled with one know-it-all after another that wants to sell you the dream. However, what many people fail to do at the start, and something that Sharpe learned along the way, is to actually understand what's going on out there in the digital world and how businesses and e-commerce works in general, before diving in headfirst.

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. 

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.
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.
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.
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.
The formula uses a model of a random surfer who gets bored after several clicks and switches to a random page. The PageRank value of a page reflects the chance that the random surfer will land on that page by clicking on a link. It can be understood as a Markov chain in which the states are pages, and the transitions, which are all equally probable, are the links between pages.
Online networking, when executed correctly, allows you to build valuable relationships in online forums and groups that can help you advance your business. You could meet peers and fellow experts with whom you could collaborate or partner up with for a project, or you could provide value to your target audience by sharing your knowledge and winning over some customers as a result. No matter what, though, the goal with this type of marketing is purely relationship building and not selling outright.
For example, if a webmaster has a website about how to rescue orphaned kittens, and received a backlink from another website about kittens, then that would be more relevant in a search engine's assessment than say a link from a site about car racing. The more relevant the site is that is linking back to your website, the better the quality of the backlink.

@Ronny – At SMX Advanced it was noted by Google that they can, and do follow JavaScript links. They also said that there is a way to provide a nofollow to a JavaScript link but they didn’t go into much detail about it. Vanessa Fox recently wrote a lengthy article about it over on Search Engine Land which will likely address any questions you might have:
While most search engine companies try to keep their processes a secret, their criteria for high spots on SERPs isn't a complete mystery. Search engines are successful only if they provide a user links to the best Web sites related to the user's search terms. If your site is the best skydiving resource on the Web, it benefits search engines to list the site high up on their SERPs. You just have to find a way to show search engines that your site belongs at the top of the heap. That's where search engine optimization (SEO) comes in -- it's a collection of techniques a webmaster can use to improve his or her site's SERP position.
“What does mean relevancy?”, – you may ask. Let’s imagine that you have blog about website building tips, but you have found an authoritative site about makeup trends. According to Google, this source won`t be a perfect one for you, because high authority sites should be closely related to yours. In other cases, it won’t work. The same thing goes for the content around which your link is inserted.
Mathematical PageRanks for a simple network, expressed as percentages. (Google uses a logarithmic scale.) Page C has a higher PageRank than Page E, even though there are fewer links to C; the one link to C comes from an important page and hence is of high value. If web surfers who start on a random page have an 85% likelihood of choosing a random link from the page they are currently visiting, and a 15% likelihood of jumping to a page chosen at random from the entire web, they will reach Page E 8.1% of the time. (The 15% likelihood of jumping to an arbitrary page corresponds to a damping factor of 85%.) Without damping, all web surfers would eventually end up on Pages A, B, or C, and all other pages would have PageRank zero. In the presence of damping, Page A effectively links to all pages in the web, even though it has no outgoing links of its own.
