For search engine optimization purposes, some companies offer to sell high PageRank links to webmasters.[40] As links from higher-PR pages are believed to be more valuable, they tend to be more expensive. It can be an effective and viable marketing strategy to buy link advertisements on content pages of quality and relevant sites to drive traffic and increase a webmaster's link popularity. However, Google has publicly warned webmasters that if they are or were discovered to be selling links for the purpose of conferring PageRank and reputation, their links will be devalued (ignored in the calculation of other pages' PageRanks). The practice of buying and selling links is intensely debated across the Webmaster community. Google advises webmasters to use the nofollow HTML attribute value on sponsored links. According to Matt Cutts, Google is concerned about webmasters who try to game the system, and thereby reduce the quality and relevance of Google search results.[40]
Paid-for links and ads on your site MUST have a nofollow attribute (see Google’s policy on nofollow). If you have paid links that are left followed, the search engines might suspect you are trying to manipulate search results and slap your site with a ranking penalty. Google’s Penguin algorithm eats manipulative paid links for lunch, so stay off the menu by adding nofollow attributes where applicable.
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.
Google wasn’t happy with the Pandora’s Box it had opened. It began to fight back, with its most famous action against a network known as SearchKing, penalizing the site and some of those in the network with PageRank score reductions or actual removal from Google. SearchKing sued Google. Google won, a judge ruling that its search results were entitled to First Amendment protection as opinions.

Hi Brian thank you for sharing this awesome backlinking techniques. My site is currently not ranking well. It used to be, sometime mid last year, but it suddenly got de-ranked. Not really sure why. I haven’t been participating in any blackhat techniques or anything at all. I’ll try a few of your tips and hopefully it will help my site back to its shape.
In 2005, in a pilot study in Pakistan, Structural Deep Democracy, SD2[61][62] was used for leadership selection in a sustainable agriculture group called Contact Youth. SD2 uses PageRank for the processing of the transitive proxy votes, with the additional constraints of mandating at least two initial proxies per voter, and all voters are proxy candidates. More complex variants can be built on top of SD2, such as adding specialist proxies and direct votes for specific issues, but SD2 as the underlying umbrella system, mandates that generalist proxies should always be used.
Before Sharpe ever came into close proximity with the internet marketing field, he was a construction worker. Needing a way to make ends meet, like millions of other people around the world, he turned to a field that could hopefully pay the bills. But try as he might, he was never able to actually get ahead. Until one day, when Sharpe discovered the amount of money being made online by internet marketers, his entire mindset changed.
“NOTE: You may be curious what your site’s or your competitor’s PR score is. But Google no longer reveals the PageRank score for websites. It used to display at the top of web browsers right in the Google Toolbar, but no more. And PR data is no longer available to developers through APIs, either. Even though it’s now hidden from public view, however, PageRank remains an important ingredient in Google’s secret ranking algorithms.”
If you’re a blogger (or a blog reader), you’re painfully familiar with people who try to raise their own websites’ search engine rankings by submitting linked blog comments like “Visit my discount pharmaceuticals site.” This is called comment spam, we don’t like it either, and we’ve been testing a new tag that blocks it. From now on, when Google sees the attribute (rel=“nofollow”) on hyperlinks, those links won’t get any credit when we rank websites in our search results.
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]
DisabledGO, an information provider for people with disabilities in the UK and Ireland, hired Agency51 to implement an SEO migration strategy to move DisabledGO from an old platform to a new one. By applying 301 redirects to old URLS, transferring metadata, setting up Google webmaster tools, and creating a new sitemap, Agency 51 was able to successfully transfer DisabledGO to a new platform while keeping their previous SEO power alive. Additionally, they were able to boost visitor numbers by 21% year over year, and the site restructuring allowed DisabledGO to rank higher than competitors. Their case study is available on
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.
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.
TrustRank takes into consideration website foundational backlinks. Searching engines find quicker sites which are reliable and trustworthy and place them on the top of SERP. All doubtful websites you can find somewhere at the end of the rank if you decide to look what is there. As a rule, people take the information from the first links and stop searching, in case they have found nothing on first 20 top sites. Surely, your website may have that required information, service or goods but because of lack of authority, Internet users will not find them unless you have good foundational backlinks. What are backlinks which we call foundational? These are all branded and non-optimized backlinks on authority websites.
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.

Matt, this is an excellent summary. I finally got around to reading “The Search” by John Battelle and it was very enlightening to understand much of the academia behind what led to the creation of Backrub.. er Google.Looking at how many times the project was almost shutdown due to bandwidth consumption (> 50% of what the university could offer at times) as well as webmasters being concerned that their pages would be stolen and recreated. It’s so interesting to see that issues we see today are some of the same ones that Larry and Sergey were dealing with back then. As always, thanks for the great read Matt!

Google will like your content if your clients like it. The content should be helpful and contain less information which is already known to the reader. It is to meet their expectations. When users vote for your site, it means that Google starts accepting it as an authority site. That’s why content writing is as important as a speech of a candidate for the Presidency. The better it is, the more visitors you have.
This pagerank theme is getting understood in simplistic ways, people are still concerning about pagerank all the time (talking about SEOs). I just use common sense, if I were the designer of a search engine, besides of using the regular structure of analysis, I would use artificial intelligence to determine many factors of the analysis. I think this is not just a matter of dividing by 10, is far more complex. I might be wrong, but I believe the use of the nofollow attribute is not a final decision of the website owner any more is more like an option given to the bot, either to accept or reject the link as valid vote. Perhaps regular links are not final decision of the webmaster too. I think Google is seeing websites human would do, the pages are not analyzed like a parser will do, I believe is more like a neural network, bit more complex. I believe this change make a little difference. People should stop worrying about pagerank and start building good content, the algorithm is far more complex to determine what is next step to reach top ten at Google. However nothing is impossible.
I compare the latest Google search results to this: Mcdonalds is the most popular and is #1 in hamburgers… they dont taste that great but people still go there. BUT I bet you know a good burger joint down the road from Google that makes awesome burgers, 10X better than Mcdonalds, but “we” can not find that place because he does not have the resources or budget to market his burgers effectively.
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.
Inclusion in Google's search results is free and easy; you don't even need to submit your site to Google. Google is a fully automated search engine that uses web crawlers to explore the web constantly, looking for sites to add to our index. In fact, the vast majority of sites listed in our results aren't manually submitted for inclusion, but found and added automatically when we crawl the web. Learn how Google discovers, crawls, and serves web pages.3
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?
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 🙂
In an effort to manually control the flow of PageRank among pages within a website, many webmasters practice what is known as PageRank Sculpting[65]—which is the act of strategically placing the nofollow attribute on certain internal links of a website in order to funnel PageRank towards those pages the webmaster deemed most important. This tactic has been used since the inception of the nofollow attribute, but may no longer be effective since Google announced that blocking PageRank transfer with nofollow does not redirect that PageRank to other links.[66]
A breadcrumb is a row of internal links at the top or bottom of the page that allows visitors to quickly navigate back to a previous section or the root page. Many breadcrumbs have the most general page (usually the root page) as the first, leftmost link and list the more specific sections out to the right. We recommend using breadcrumb structured data markup28 when showing breadcrumbs.
