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?

If you're not using internet marketing to market your business you should be. An online presence is crucial to helping potential clients and customer find your business - even if your business is small and local. (In 2017, one third of all mobile searches were local and local search was growing 50% faster than mobile searches overall.) Online is where the eyeballs are so that's where your business needs to be. 

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.
Of course, it’s possible that the algorithm has some method of discounting internally reflected (and/or directly reciprocal) links (particularly those in identical headers or footers) to such an extent that this isn’t important. Evidence to support this the fact that many boring pages that are linked to by every page in a good site can have very low PR.
Suppose instead that page B had a link to pages C and A, page C had a link to page A, and page D had links to all three pages. Thus, upon the first iteration, page B would transfer half of its existing value, or 0.125, to page A and the other half, or 0.125, to page C. Page C would transfer all of its existing value, 0.25, to the only page it links to, A. Since D had three outbound links, it would transfer one third of its existing value, or approximately 0.083, to A. At the completion of this iteration, page A will have a PageRank of approximately 0.458.
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)
Great post. I’m posting a link back to this article from our blog along with some comments. I do have a question. In your article, you post “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.” Yet when I look at this article, I noticed that the comment links are “external, nofollow”. Is there a reason for that?
Backlinks can be time-consuming to earn. New sites or those expanding their keyword footprint may find it difficult to know where to start when it comes to link building. That's where competitive backlink research comes in: By examining the backlink profile (the collection of pages and domains linking to a website) to a competitor that's already ranking well for your target keywords, you can gain insight about the link building that may have helped them. A tool like Link Explorer can help uncover these links so you can and target those domains in your own link building campaigns.

If you're serious about finding your voice and discovering the secrets to success in business, one of the best people to follow is Gary Vanyerchuck, CEO of Vayner Media, and early-stage invest in Twitter, Uber and Facebook, has arbitraged his way into the most popular social media platforms and built up massive followings and often spills out the secrets to success in a highly motivating and inspiring way.

In December 2009, Google announced it would be using the web search history of all its users in order to populate search results.[32] On June 8, 2010 a new web indexing system called Google Caffeine was announced. Designed to allow users to find news results, forum posts and other content much sooner after publishing than before, Google caffeine was a change to the way Google updated its index in order to make things show up quicker on Google than before. According to Carrie Grimes, the software engineer who announced Caffeine for Google, "Caffeine provides 50 percent fresher results for web searches than our last index..."[33] Google Instant, real-time-search, was introduced in late 2010 in an attempt to make search results more timely and relevant. Historically site administrators have spent months or even years optimizing a website to increase search rankings. With the growth in popularity of social media sites and blogs the leading engines made changes to their algorithms to allow fresh content to rank quickly within the search results.[34]
Another illicit practice is to place "doorway" pages loaded with keywords on the client's site somewhere. The SEO promises this will make the page more relevant for more queries. This is inherently false since individual pages are rarely relevant for a wide range of keywords. More insidious, however, is that these doorway pages often contain hidden links to the SEO's other clients as well. Such doorway pages drain away the link popularity of a site and route it to the SEO and its other clients, which may include sites with unsavory or illegal content.
If the algorithm really works as Matt suggests, no one should use nofollow links internally. I’ll use the example that Matt gave. Suppose you have a home page with ten PR “points.” You have links to five “searchable” pages that people would like to find (and you’d like to get found!), and links to five dull pages with disclaimers, warranty info, log-in information, etc. But, typically, all of the pages will have links in headers and footers back to the home page and other “searchable” pages. So, by using “nofollow” you lose some of the reflected PR points that you’d get if you didn’t use “nofollow.” I understand that there’s a decay factor, but it still seems that you could be leaking points internally by using “nofollow.”
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?

Having a different description meta tag for each page helps both users and Google, especially in searches where users may bring up multiple pages on your domain (for example, searches using the site: operator). If your site has thousands or even millions of pages, hand-crafting description meta tags probably isn't feasible. In this case, you could automatically generate description meta tags based on each page's content.

As Rogers pointed out in his classic paper on PageRank, the biggest takeaway for us about the eigenvector piece is that it’s a type of math that let’s you work with multiple moving parts. “We can go ahead and calculate a page’s PageRank without knowing the final value of the PR of the other pages. That seems strange but, basically, each time we run the calculation we’re getting a closer estimate of the final value. So all we need to do is remember the each value we calculate and repeat the calculations lots of times until the numbers stop changing much.”
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.
Search engines may penalize sites they discover using black hat methods, either by reducing their rankings or eliminating their listings from their databases altogether. Such penalties can be applied either automatically by the search engines' algorithms, or by a manual site review. One example was the February 2006 Google removal of both BMW Germany and Ricoh Germany for use of deceptive practices.[53] Both companies, however, quickly apologized, fixed the offending pages, and were restored to Google's list.[54]

And if you really want to know what are the most important, relevant pages to get links from, forget PageRank. Think search rank. Search for the words you’d like to rank for. See what pages come up tops in Google. Those are the most important and relevant pages you want to seek links from. That’s because Google is explicitly telling you that on the topic you searched for, these are the best.
In March 2006, KinderStart filed a lawsuit against Google over search engine rankings. KinderStart's website was removed from Google's index prior to the lawsuit and the amount of traffic to the site dropped by 70%. On March 16, 2007 the United States District Court for the Northern District of California (San Jose Division) dismissed KinderStart's complaint without leave to amend, and partially granted Google's motion for Rule 11 sanctions against KinderStart's attorney, requiring him to pay part of Google's legal expenses.[69][70]
I agree that the more facts that you provide and if you were to provide the complete algorithm, people would abuse it but if it were available to everyone, would it not almost force people to implement better site building and navigation policies and white hat seo simply because everyone would have the same tools to work with and an absolute standard to adhere to.

There is no secret that getting hiqh-quality backlinks is your website’s way to better ranking in Google. But how to differ good link from the bad one? Carefully choosing backlinks is a very tremulous and important task for everyone who wants to optimize their sites. There are a lot of different tools which can help you to check whether your backlinks are trustful and can bring your website value. 
When calculating PageRank, pages with no outbound links are assumed to link out to all other pages in the collection. Their PageRank scores are therefore divided evenly among all other pages. In other words, to be fair with pages that are not sinks, these random transitions are added to all nodes in the Web. This residual probability, d, is usually set to 0.85, estimated from the frequency that an average surfer uses his or her browser's bookmark feature. So, the equation is as follows:
The PageRank algorithm has major effects on society as it contains a social influence. As opposed to the scientific viewpoint of PageRank as an algorithm the humanities instead view it through a lens examining its social components. In these instances, it is dissected and reviewed not for its technological advancement in the field of search engines, but for its societal influences.[42] Laura Granka discusses PageRank by describing how the pages are not simply ranked via popularity as they contain a reliability that gives them a trustworthy quality. This has led to a development of behavior that is directly linked to PageRank. PageRank is viewed as the definitive rank of products and businesses and thus, can manipulate thinking. The information that is available to individuals is what shapes thinking and ideology and PageRank is the device that displays this information. The results shown are the forum to which information is delivered to the public and these results have a societal impact as they will affect how a person thinks and acts.
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.
Balancing search and display for digital display ads are important; marketers tend to look at the last search and attribute all of the effectiveness to this. This then disregards other marketing efforts, which establish brand value within the consumers mind. ComScore determined through drawing on data online, produced by over one hundred multichannel retailers that digital display marketing poses strengths when compared with or positioned alongside, paid search (Whiteside, 2016).[42] This is why it is advised that when someone clicks on a display ad the company opens a landing page, not its home page. A landing page typically has something to draw the customer in to search beyond this page. Things such as free offers that the consumer can obtain through giving the company contact information so that they can use retargeting communication strategies (Square2Marketing, 2012).[43] Commonly marketers see increased sales among people exposed to a search ad. But the fact of how many people you can reach with a display campaign compared to a search campaign should be considered. Multichannel retailers have an increased reach if the display is considered in synergy with search campaigns. Overall both search and display aspects are valued as display campaigns build awareness for the brand so that more people are likely to click on these digital ads when running a search campaign (Whiteside, 2016).[42]
1. Apparently, external linking of any kind bleeds PR from the page. Following or nofollowing becomes a function of whether you want that lost PR to benefit the other site. Since nofollow has ceased to provide the benefit of retaining pagerank, the only reason to use it at all is Google Might Think This Link Is Paid. Conclusion: Google is disincentivizing external links of any kind.
When Googlebot crawls a page, it should see the page the same way an average user does15. For optimal rendering and indexing, always allow Googlebot access to the JavaScript, CSS, and image files used by your website. If your site's robots.txt file disallows crawling of these assets, it directly harms how well our algorithms render and index your content. This can result in suboptimal rankings.
Writing blog posts is especially effective for providing different opportunities to land on page one of search engines -- for instance, maybe your eyeglass store’s website is on page three of Google for “eyeglasses,” but your “Best Sunglasses of 2018” blog post is on page one, pulling in an impressive amount of traffic (over time, that blog post could also boost your overall website to page one).

PageRank as a visible score has been dying a slow death since around 2010, I’d say. Pulling it from the Google Toolbar makes it official, puts the final nail in the visible PageRank score coffin. The few actually viewing it within Internet Explorer, itself a depreciated browser, aren’t many. The real impact in dropping it from the toolbar means that third parties can no longer find ways to pull those scores automatically.

Internet usage around the world, especially in the wealthiest countries, has steadily risen over the past decade and it shows no signs of slowing. According to a report by the Internet trend investment firm Kleiner Perkins Caulfield & Byers, 245 million people in the United States were online as of 2011, and 15 million people connected for the first time that year. As Internet usage grows, online commerce grows with it. This means that more people are using the Internet with each passing year, and enough of them are spending money online to impact the economy in significant ways. (See also E-Commerce Marketing)

It helps to improve your ranking for certain keywords. If we want this article to rank for the term ’SEO basics’ then we can begin linking to it from other posts using variations of similar anchor text. This tells Google that this post is relevant to people searching for ‘SEO basics’. Some experts recommend varying your anchor text pointing to the same page as Google may see multiple identical uses as ‘suspicious’.
There is much discussion in these last few months about reciprocal linking. In the last Google update, reciprocal links were one of the targets of the search engine's latest filter. Many webmasters had agreed upon reciprocal link exchanges, in order to boost their site's rankings with the sheer number of inbound links. In a link exchange, one webmaster places a link on his website that points to another webmasters website, and vice versa. Many of these links were simply not relevant, and were just discounted. So while the irrelevant inbound link was ignored, the outbound links still got counted, diluting the relevancy score of many websites. This caused a great many websites to drop off the Google map.

In regards to link sculpting I think the pro’s of having the “no follow” attribute outweigh the few who might use it to link sculpt. Those crafty enough to link sculpt don’t actually need this attribute but it does make life easier and is a benefit. Without this attribute I would simply change the hierarchy of the internal linking structure of my site and yield the same results I would if the “no follow” attribute didn’t exist.
A press release can serve double duty for marketing efforts. It can alert media outlets about your news and also help your website gain backlinks. But it can only build links effectively if executed properly. Only write and distribute press releases when a brand has something newsworthy or interesting to share Click & Tweet! . This strategy can gain links on the actual press release post as well as on the stories that media outlets write about it.
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.
The SEO industry changes at an extreme pace, every year marketers evolve their strategies and shift their focus. However, backlinks remain just as crucial of a strategy as when they were first created. Currently, backlinks are a very common phase in the world of SEO, and if you are involved in the industry, you know backlinks are vital to a website’s performance.

As an avid reader of [insert their site name], I love reading anything you write about, such as [insert article on their website], and anything you link out to. Sadly, I couldn’t find the article you were trying to link to, but I did happen to find another good webpage on the same topic: [insert url to webpage that you are building links to]. You should check it out, and if you like it, you probably want to switch the links.
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.
This must be one of the most controversial attributes ever. I participate in photographic communities. The textual content there is quite sparse, as it is a visual medium, with only basic descriptions. However, the community is very active and the participants leave a lot of meaningful comments. Now, with the “nofollow” used everywhere the photographic community is punishing itself for being active and interactive without knowing it. WordPress and Pixelpost now have “nofollow” built in almost on any list of links (blog-roll, comments etc). The plug-in and theme developers for these platforms followed suit and yes, you’ve guessed it – added “nofollow” almost on every link. So, every time I leave a comment without being an anonymous coward or if some one likes my blog and links to it in their blog-roll than I’m or they are diluting the rank of my blog? Does it mean for my own good I should stop participating in the community? Should I visit hundreds of blogs I visited in last three years and ask the owners to remove my comments and remove my site from their blog-roll to stop my PageRank from free falling?

Matt Cutts, it’s Shawn Hill from Longview, Texas and I’ve got to say, “you’re a semseo guru”. That’s obviously why Google retained you as they did. Very informative post! As head of Google’s Webspam team how to you intend to combat Social Networking Spam (SNS)? It’s becoming an increasingly obvious problem in SERPs. I’m thinking Blogspam should be the least of Google’s worries. What’s your take?
