Black hat SEO attempts to improve rankings in ways that are disapproved of by the search engines, or involve deception. One black hat technique uses text that is hidden, either as text colored similar to the background, in an invisible div, or positioned off screen. Another method gives a different page depending on whether the page is being requested by a human visitor or a search engine, a technique known as cloaking. Another category sometimes used is grey hat SEO. This is in between black hat and white hat approaches, where the methods employed avoid the site being penalized, but do not act in producing the best content for users. Grey hat SEO is entirely focused on improving search engine rankings.
i.e. the PageRank value for a page u is dependent on the PageRank values for each page v contained in the set Bu (the set containing all pages linking to page u), divided by the number L(v) of links from page v. The algorithm involves a damping factor for the calculation of the pagerank. It is like the income tax which the govt extracts from one despite paying him itself.

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.
Why do so many people spend so much time researching SEO and page rank? Its really not that hard to figure out, (I am speaking in a nice tone by the way =) – all you should need to be focusing on is advertising and building your website in a manner that is ethical, operational and practical for the content and industry that your website is in/about. If you are not up-to-something, then google will know it, and they will rank you accordingly. If you spend so much time trying to figure out how to get to the top, I bet you google spends triple that time figuring out how to figure out how your trying to get to the top. So and and so forth…and your not going to win. Have good content not copied, stay away from to many out bound links especially affiliates, post your backlinks at places that have something to do with your site, etc etc… Is it an American thing, I don’t seem to see it as bad in other places of the world, that is “always trying to figure out an easy way, a quick fix, a way to not have to put in the effort…” anyway… Thanks for letting me vent. Please not nasty replies. Keep it to your self = )
Before online marketing channels emerged, the cost to market products or services was often prohibitively expensive, and traditionally difficult to measure. Think of national television ad campaigns, which are measured through consumer focus groups to determine levels of brand awareness. These methods are also not well-suited to controlled experimentation. Today, anyone with an online business (as well as most offline businesses) can participate in online marketing by creating a website and building customer acquisition campaigns at little to no cost. Those marketing products and services also have the ability to experiment with optimization to fine-tune their campaigns’ efficiency and ROI.
The internet is full of business potential, but it is also rife with competition. In this situation, it becomes really tough to sell your products or services. Affiliate marketing can help you effectively promote your product on the web. By helping you reach out to a large potential customer base, affiliate programs help you to connect with millions of customers across the globe.
By using Internet platforms, businesses can create competitive advantage through various means. To reach the maximum potential of digital marketing, firms use social media as its main tool to create a channel of information. Through this a business can create a system in which they are able to pinpoint behavioral patterns of clients and feedback on their needs.[30] This means of content has shown to have a larger impingement on those who have a long-standing relationship with the firm and with consumers who are relatively active social media users. Relative to this, creating a social media page will further increase relation quality between new consumers and existing consumers as well as consistent brand reinforcement therefore improving brand awareness resulting in a possible rise for consumers up the Brand Awareness Pyramid.[31] Although there may be inconstancy with product images;[32] maintaining a successful social media presence requires a business to be consistent in interactions through creating a two way feed of information; firms consider their content based on the feedback received through this channel, this is a result of the environment being dynamic due to the global nature of the internet.[29] Effective use of digital marketing can result in relatively lowered costs in relation to traditional means of marketing; Lowered external service costs, advertising costs, promotion costs, processing costs, interface design costs and control costs.[32]

Backlinks are a major ranking factor for most search engines, including Google. If you want to do SEO for your website and get relevant organic traffic, building backlinks is something you should be doing. The more backlinks your website has from authoritative domains, the higher reputation you’ll have in Google’s eyes. And you’ll dominate the SERPS.

If you build a new site and only used Domain Authority to create links, you could EASILY have got linked from the worst page possible, even if it was from the best domain, because of the INTERNAL LINKS of the other web pages! How on earth are you going to be able to see the strength of a link if that strength depends on the internal links on an entirely different website?!

I’m growing tired of this game between Google and the rest of the online community about how to “manipulate” my content and code to better rank in your system. It seems that you guys have completely over complicated the game. If I add a nofollow tag, why on earth would any page rank be added to that link. I just told you to NOT FOLLOW it! The fact that it receives any rank at all is absurd.
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.
The probability for the random surfer not stopping to click on links is given by the damping factor d, which is, depending on the degree of probability therefore, set between 0 and 1. The higher d is, the more likely will the random surfer keep clicking links. Since the surfer jumps to another page at random after he stopped clicking links, the probability therefore is implemented as a constant (1-d) into the algorithm. Regardless of inbound links, the probability for the random surfer jumping to a page is always (1-d), so a page has always a minimum PageRank.
World Wide Web, or “the web” for short, is a network of web pages connected to each other via hyperlinks. Each hyperlink connecting to a new document adds to the overall growth of the web. Search engines make it easier for you to find these web pages. A web page linked by many other web pages on the similar topics is considered more respectful and valuable. In the above example, John’s article gets the respect for sparking a conversation that resulted into many other web pages linking to each other. So backlinks are not only important for a website to gain respect, they are also important for search engines and the overall health of the entire world wide web.
Peter made a very good point in all of this, and Michael Martinez did in a backhanded way as well. Talking about a concept related PageRank sounds cool. It doesn’t actually have to be useful or practical, and it usually isn’t; but as long as the impression of something productive is given off, then that can be all that matters in the eyes of those who lack sufficient knowledge.

Start Value (In this case) is the number of actual links to each “node”. Most people actually set this to 1 to start, but there are two great reasons for using link counts. First, it is a better approximation to start with than giving everything the same value, so the algorithm stabilizes in less iterations and it is so useful to check my spreadsheet in a second… so node A has one link in (from page C)

SEO is not an appropriate strategy for every website, and other Internet marketing strategies can be more effective like paid advertising through pay per click (PPC) campaigns, depending on the site operator's goals. Search engine marketing (SEM), is practice of designing, running, and optimizing search engine ad campaigns.[55] Its difference from SEO is most simply depicted as the difference between paid and unpaid priority ranking in search results. Its purpose regards prominence more so than relevance; website developers should regard SEM with the utmost importance with consideration to visibility as most navigate to the primary listings of their search.[56] A successful Internet marketing campaign may also depend upon building high quality web pages to engage and persuade, setting up analytics programs to enable site owners to measure results, and improving a site's conversion rate.[57] In November 2015, Google released a full 160 page version of its Search Quality Rating Guidelines to the public,[58] which now shows a shift in their focus towards "usefulness" and mobile search. In recent years the mobile market has exploded, overtaking the use of desktops as shown in by StatCounter in October 2016 where they analysed 2.5 million websites and 51.3% of the pages were loaded by a mobile device [59]. Google has been one of the companies that have utilised the popularity of mobile usage by encouraging websites to use their Google Search Console, the Mobile-Friendly Test, which allows companies to measure up their website to the search engine results and how user-friendly it is.
There are also many keyword research tools (some free and some paid) that claim to take the effort out of this process. A popular tool for first timers is Traffic Travis, which can also analyse your competitors’ sites for their keyword optimization strategies and, as a bonus, it can deliver detailed analysis on their back-linking strategy, too. You can also use Moz.com’s incredibly useful keyword research tools – they’re the industry leader, but they come at a somewhat higher price.
Well, it seems that what this article says, is that the purpose of the no-follow link is to take the motivation away from spammers to post spam comments for the purpose of the link and the associated page rank flow; that the purpose of no-follow was never to provide a means to control where a page’s pagerank flow is directed. It doesn’t seem that shocking to me folks.
Should have added in my previous comment that our site has been established since 2000 and all our links have always been followable – including comment links (but all are manually edited to weed out spambots). We have never artificially cultivated backlinks but I have noticed that longstanding backlinks from established sites like government and trade organisations are changing to ‘nofollow’ (and our homepage PR has declined from 7 to 4 over the past 5 years). If webmasters of the established sites are converting to systems which automatically change links to ‘nofollow’ then soon the only followable links will be those that are paid for – and the blackhats win again.
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.
The green ratings bars are a measure of the importance Google’s assessment of the importance of a web page, as determined by Google’s patented PageRank technology and other factors. These PageRank bars tell you at a glance whether other people on the web consider Google considers a page to be a high-quality site worth checking out. Google itself does not evaluate or endorse websites. Rather, we measure what others on the web feel is important enough to deserve a link. And because Google does not accept payment for placement within our results, the information you see when you conduct a search is based on totally objective criteria.

Provide full functionality on all devices. Mobile users expect the same functionality - such as commenting and check-out - and content on mobile as well as on all other devices that your website supports. In addition to textual content, make sure that all important images and videos are embedded and accessible on mobile devices. For search engines, provide all structured data and other metadata - such as titles, descriptions, link-elements, and other meta-tags - on all versions of the pages.
Goals and Objectives. Clearly define your objectives in advance so you can truly measure your ROI from any programs you implement. Start simple, but don’t skip this step. Example: You may decide to increase website traffic from a current baseline of 100 visitors a day to 200 visitors over the next 30 days. Or you may want to improve your current conversion rate of one percent to two in a specified period. You may begin with top-level, aggregate numbers, but you must drill down into specific pages that can improve products, services, and business sales.
Backlink is a link one website gets from another website. Backlinks make a huge impact on a website’s prominence in search engine results. This is why they are considered very useful for improving a website’s SEO ranking. Search engines calculate rankings using multiple factors to display search results. No one knows for sure how much weight search engines give to backlinks when listing results, however what we do know for certain is that they are very important.
By 2004, search engines had incorporated a wide range of undisclosed factors in their ranking algorithms to reduce the impact of link manipulation. In June 2007, The New York Times' Saul Hansell stated Google ranks sites using more than 200 different signals.[25] The leading search engines, Google, Bing, and Yahoo, do not disclose the algorithms they use to rank pages. Some SEO practitioners have studied different approaches to search engine optimization, and have shared their personal opinions.[26] Patents related to search engines can provide information to better understand search engines.[27] In 2005, Google began personalizing search results for each user. Depending on their history of previous searches, Google crafted results for logged in users.[28] 

The search engine results page (SERP) is the actual result returned by a search engine in response to a keyword query. The SERP consists of a list of links to web pages with associated text snippets. The SERP rank of a web page refers to the placement of the corresponding link on the SERP, where higher placement means higher SERP rank. The SERP rank of a web page is a function not only of its PageRank, but of a relatively large and continuously adjusted set of factors (over 200).[35] Search engine optimization (SEO) is aimed at influencing the SERP rank for a website or a set of web pages.

If you’re Matt Cutts and a billion people link to you because you’re the Spam guy at Google, writing great content is enough. For the rest of us in hypercompetitive markets, good content alone is not enough. There was nothing wrong with sculpting page rank to pages on your site that make you money as a means of boosting traffic to those pages. It’s not manipulating Google, there’s more than enough of that going on in the first page of results for most competitive keywords. Geez Matt, give the little guy a break!
Just a related note in passing: On October 6, 2013 Matt Cutts (Google’s head of search spam) said Google PageRank Toolbar won’t see an update before 2014. He also published this helpful video that talks more in depth about how he (and Google) define PageRank, and how your site’s internal linking structure (IE: Your siloing structure) can directly affect PageRank transfer. Here’s a link to the video: http://youtu.be/M7glS_ehpGY.
Optimization techniques are highly tuned to the dominant search engines in the target market. The search engines' market shares vary from market to market, as does competition. In 2003, Danny Sullivan stated that Google represented about 75% of all searches.[63] In markets outside the United States, Google's share is often larger, and Google remains the dominant search engine worldwide as of 2007.[64] As of 2006, Google had an 85–90% market share in Germany.[65] While there were hundreds of SEO firms in the US at that time, there were only about five in Germany.[65] As of June 2008, the market share of Google in the UK was close to 90% according to Hitwise.[66] That market share is achieved in a number of countries.
Hey brian, it is extremely fantastic stuff, i am not getting words to appreciate your work..brilliant. No one dares to share their business secrets with others but you are awesome and thank you so much. Iam a beginner in digital marketing, iam learning consistently by following your posts, tips and tricks. eventually i became an intermediate person thanks for your help.
Spam is a poison that in different ways (and in different names) affects many things. Matt, you and your guys do a great job in trying to keep it at bay. But, as mentioned before, with that role and power, you set the rules for the web in many ways. As I have said before even though the JavaScript link change is not (in Danny’s words) backward compatible, it is understandable. I will maintain that the PageRank sculpting thing is not the same.
The original Random Surfer PageRank patent from Stanford has expired. The Reasonable Surfer version of PageRank (assigned to Google) is newer than that one, and has been updated via a continuation patent at least once. The version of PageRank based upon a trusted seed set of sites (assigned to Google) has also been updated via a continuation patent and differs in many ways from the Stanford version of PageRank. It is likely that Google may be using one of the versions of PageRank that they have control over (the exclusive license to use Stanford’s version of PageRank has expired along with that patent). The updated versions of PageRank (reasonable surfer and Trusted Seeds approach) both are protected under present day patents assigned to Google, and both have been updated to reflect modern processes in how they are implemented. Because of their existence, and the expiration of the original, I would suggest that it is unlikely that the random surfer model-base PageRank is still being used.
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.
