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.
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.
Organic SEO's flip-side offers up a paid method for marketing on search engines like Google. SEM provides an avenue for displaying ads through networks such as Google's Adwords and other paid search platforms that exist across the web throughout social media sites like Facebook, Instagram and even video sites like YouTube, which, invariably, is the world's second largest search engine.
A navigational page is a simple page on your site that displays the structure of your website, and usually consists of a hierarchical listing of the pages on your site. Visitors may visit this page if they are having problems finding pages on your site. While search engines will also visit this page, getting good crawl coverage of the pages on your site, it's mainly aimed at human visitors.

PageRank always was and remains only one part of the Google search algorithm, the system that determines how to rank pages. There are many other ranking factors that are also considered. A high PageRank score did NOT mean that a page would rank well for any topic. Pages with lower scores could beat pages with higher scores if they had other factors in their favor.

Now, how much weight does PageRank carry? Like most every other part of the algorithm, it’s questionable. If we listed all the ranking factors, I don’t suspect it would be in the top 5, but it’s important to remember that the key to ranking well is to be the LESS IMPERFECT than your competition. IE: To have more of the right things that send the right signals in the right places so that Google sees you as a better, more relevant, candidate for the top three on page one. If you and your competitor both have optimized (on-page and technically) for the same keyword phrase perfectly, PR could be the deal breaker that pushes your blue link an inch up.
For the purpose of their second paper, Brin, Page, and their coauthors took PageRank for a spin by incorporating it into an experimental search engine, and then compared its performance to AltaVista, one of the most popular search engines on the Web at that time. Their paper included a screenshot comparing the two engines’ results for the word “university.”
Just think about any relationship for a moment. How long you've known a person is incredibly important. It's not the be-all-end-all, but it is fundamental to trust. If you've known someone for years and years and other people that you know who you already trust can vouch for that person, then you're far more likely to trust them, right? But if you've just met someone, and haven't really vetted them so to speak, how can you possibly trust them?

Search engines are smart, but they still need help. The major engines are always working to improve their technology to crawl the web more deeply and return better results to users. However, there is a limit to how search engines can operate. Whereas the right SEO can net you thousands of visitors and increased attention, the wrong moves can hide or bury your site deep in the search results where visibility is minimal.
While the obvious purpose of internet marketing is to sell goods, services or advertising over the internet, it's not the only purpose a business using internet marketing may have; a company may be marketing online to communicate a message about itself (building its brand) or to conduct research. Online marketing can be a very effective way to identify a target market or discover a marketing segment's wants and needs. (Learn more about conducting market research).
According to Statistica, 76% of the U.S. population has at least one social networking profile and by 2020 the number of worldwide users of social media is expected to reach 2.95 billion (650 million of these from China alone). Of the social media platforms, Facebook is by far the most dominant - as of the end of the second quarter of 2018 Facebook had approximately 2.23 billion active users worldwide (Statistica). Mobile devices have become the dominant platform for Facebook usage - 68% of time spent on Facebook originates from mobile devices.

The eigenvalue problem was suggested in 1976 by Gabriel Pinski and Francis Narin, who worked on scientometrics ranking scientific journals,[8] in 1977 by Thomas Saaty in his concept of Analytic Hierarchy Process which weighted alternative choices,[9] and in 1995 by Bradley Love and Steven Sloman as a cognitive model for concepts, the centrality algorithm.[10][11]
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.
What seems to be happening is that the toolbar looks at the URL of the page the browser is displaying and strips off everything down the last “/” (i.e. it goes to the “parent” page in URL terms). If Google has a Toolbar PR for that parent then it subtracts 1 and shows that as the Toolbar PR for this page. If there’s no PR for the parent it goes to the parent’s parent’s page, but subtracting 2, and so on all the way up to the root of your site.  If it can’t find a Toolbar PR to display in this way, that is if it doesn’t find a page with a real calculated PR, then the bar is greyed out.

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

A: I pretty much let PageRank flow freely throughout my site, and I’d recommend that you do the same. I don’t add nofollow on my category or my archive pages. The only place I deliberately add a nofollow is on the link to my feed, because it’s not super-helpful to have RSS/Atom feeds in web search results. Even that’s not strictly necessary, because Google and other search engines do a good job of distinguishing feeds from regular web pages.
Secondly, nofollow is also essential on links to off-topic pages, whether they’re internal or external to your site. You want to prevent search engines from misunderstanding what your pages are about. Linking relevant pages together reinforces your topic relevance. So to keep your topic silos clear, strategic use of the nofollow attribute can be applied when linking off-topic pages together.
Another way to get sites to link back to something valuable on your site is by offering a free tool. A free tool could be a basic tool (like an auto loan calculator) or a scaled down version of a paid tool (like Alexa’s Site Overview and Audience Overlap tools). If the tools are valuable enough, others will link to them in their content. Plus, on free versions of paid tools, you can add call-to-actions to sign up for the full product/service which drives acquisition in addition to awareness.
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.
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.

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.

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.
If you’re new to internet marketing and wish to get online as quickly and inexpensively as possible you can start with a social media platform like Facebook - you can create a business Facebook page in less than an hour. However, if you want more control over your online presence, a customized website is more appropriate. Ideally you should have both a website and a social media presence, with each linking to the other.
So, as you build a link, ask yourself, "am I doing this for the sake of my customer or as a normal marketing function?" If not, and you're buying a link, spamming blog comments, posting low-quality articles and whatnot, you risk Google penalizing you for your behavior. This could be as subtle as a drop in search ranking, or as harsh as a manual action, getting you removed from the search results altogether!
