I think Matt Grenville’s comment is a very valid one. If your site, for whatever reason, can not attract links naturally and all of your competitors are outranking you by employing tactics that might breach Google’s TOS, what other options do you have? As well as this people will now only link to a few, trusted sites (as this has been clarified in your post as being part of Google’s algorithm) and put a limit on linking out to the smaller guys.
The nofollow tag is being used for page rank sculpting and to stop blog spamming. In my mind this is tant amount to manipulating page rank and thus possibly ranking position in certain cases. I do post to regularly blogs and forums regarding web design and this improved my search ranking as a side effect. Whats wrong with making an active contribution to the industry blogs and being passed some Pagerank. Google needs to determine whether the post entry is relevant then decide to pass pagerank after the analysis or just decide that blog should not pass PR in any event. Whats gone wrong with the Internet when legitimate content pages do not pass PR?
Suggesting that this change is really just the equivalent of “resetting” things to the way they were is absurd. nofollow is still be using on outbound links in mass by the most authoritative/trusted sites on the web. Allowing us peons to have a slight bit of control over our internal juice flow simply allowed us to recoup a small portion of the overall juice that we lost when the top-down flow was so dramatically disrupted.
For instance, you might use Facebook’s Lookalike Audiences to get your message in front of an audience similar to your core demographic. Or, you could pay a social media influencer to share images of your products to her already well-established community. Paid social media can attract new customers to your brand or product, but you’ll want to conduct market research and A/B testing before investing too much in one social media channel.
If you are serious about improving web traffic to your website, we recommend you read Google Webmasters and Webmaster Guidelines. These contain the best practices to help Google (and other search engines) find, crawl, and index your website. After you have read them, you MUST try our Search Engine Optimization Tools to help you with Keyword Research, Link Building, Technical Optimization, Usability, Social Media Strategy and more.
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.
Pagerank has recently been used to quantify the scientific impact of researchers. The underlying citation and collaboration networks are used in conjunction with pagerank algorithm in order to come up with a ranking system for individual publications which propagates to individual authors. The new index known as pagerank-index (Pi) is demonstrated to be fairer compared to h-index in the context of many drawbacks exhibited by h-index.[63]
SEO may generate an adequate return on investment. However, search engines are not paid for organic search traffic, their algorithms change, and there are no guarantees of continued referrals. Due to this lack of guarantees and certainty, a business that relies heavily on search engine traffic can suffer major losses if the search engines stop sending visitors.[60] Search engines can change their algorithms, impacting a website's placement, possibly resulting in a serious loss of traffic. According to Google's CEO, Eric Schmidt, in 2010, Google made over 500 algorithm changes – almost 1.5 per day.[61] It is considered wise business practice for website operators to liberate themselves from dependence on search engine traffic.[62] In addition to accessibility in terms of web crawlers (addressed above), user web accessibility has become increasingly important for SEO.

Okay. Okay. There is a lot to learn. However, everyone has to start somewhere. If you're just being introduced to internet marketing, and you've become bedazzled by the glitz and the glamor of the top online income earners, know that it's not going to be easy to replicate their success. Be sure that you set your expectations the proper way. As long as you stay persistent, you can achieve your goals of generating healthy amounts of money online without becoming the victim of a scam.

PageRank relies on the uniquely democratic nature of the web by using its vast link structure as an indicator of an individual page’s value. In essence, Google interprets a link from page A to page B as a vote, by page A, for page B. But, Google looks at considerably more than the sheer volume of votes, or links a page receives; for example, it also analyzes the page that casts the vote. Votes cast by pages that are themselves “important” weigh more heavily and help to make other pages “important.” Using these and other factors, Google provides its views on pages’ relative importance.
Infographics are one of the most popular methods for bringing traffic to your website and gaining valuable backlinks. They're also great because they're easy to understand and share. Everyone loves visual data, right? That's why the demand for infographics has increased considerably. Consider that influential online publications like Mashable publish numerous infographics from all over the Internet.

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.

A content specialist needs to be a Jack or Jill of all trades, utilizing excellent written and verbal communication skills, above-average computer literacy, and a natural interest in trends. This job is ultimately about translating the key aspects of the product into content the target demographic finds appealing. This is part art, part critical thinking, and 100% attention to detail.
But how do you get quoted in news articles? Websites such as HARO and ProfNet can help you to connect with journalists who have specific needs, and there are other tools that allow you to send interesting pitches to writers. Even monitoring Twitter for relevant conversations between journalists can yield opportunities to connect with writers working on pieces involving your industry.

Every mechanism or algorithm is good untill someone brake it. In my opinion as people tend to scam the search results, google is getting more and more consevative upon indexing and ranking search results. When I search a word or a phrase I see more wikipedia, amazon, google, youtube, etc. links returning my search, even the page name or headline does not cover the keywords in the phrase. I’m getting afraid that this may lead to an elitist web nature in the future.
Search engine marketing (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 so you can make a sale. Start-ups should approach SEM with care. Make sure you completely understand how much money you have exposed at any one time. Don’t get carried away with the lure of quick victories. Start slow, and evaluate your results.
For example this page. My program found almost 400 nofollow links on this page. (Each comment has 3). And then you have almost 60 navigation links. My real question is how much percentage of the PageRank on this page gets distributed to the 9 real links in the article? If it is a division of 469 which some SEO experts now are claiming it is really disturbing. You won’t earn much from the links if you follow what I am saying.
Also, by means of the iterative calculation, the sum of all pages' PageRanks still converges to the total number of web pages. So the average PageRank of a web page is 1. The minimum PageRank of a page is given by (1-d). Therefore, there is a maximum PageRank for a page which is given by dN+(1-d), where N is total number of web pages. This maximum can theoretically occur, if all web pages solely link to one page, and this page also solely links to itself.

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.
On the other hand, all of the results for the PageRank engine (aside from a single secondary listing) link to the homepage of major American universities. The results are much more logical and useful in nature. If you search for “university,” are you going to want the homepages for popular universities, or random subpages from a sprinkling of colleges all over the world?
Adjusting how Google treats nofollows is clearly a major shift (as the frenzy in the SEO community has demonstrated). So, if Google were to adjust how they treat nofollows they would need to phase it in gradually. I believe this latest (whether in 2008 or 2009) change is simply a move in the direction of greater changes to come regarding nofollow. It is the logical first step.
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.
I really hope that folks don’t take the idea of disabling comments to heart… first that isn’t much fun for you the blog owner or your visitors. Second… I just did a cursory glance at the SERPS for ‘pagerank sculpting’ (how I found this post). Interestingly enough, the number of comments almost has a direct correlation with the ranking of the URL. I’m not so certain that there is a causal relationship there. But I would certainly consider that Google probably has figured out how to count comments on a WP blog and probably factors that into ranking. I know that I would.
There are ten essential types of marketing that can be done online. Some of these can be broken down into organic marketing and others can be categorized as paid marketing. Organic, of course, is the allure of marketing professionals from around the planet. It's free and its unencumbered traffic that simply keeps coming. Paid marketing, on the other hand, is still a very attractive proposition as long as the marketing pays for itself by having the right type of offer that converts.
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.
Of course, important pages mean nothing to you if they don’t match your query. So, Google combines PageRank with sophisticated text-matching techniques to find pages that are both important and relevant to your search. Google goes far beyond the number of times a term appears on a page and examines all dozens of aspects of the page’s content (and the content of the pages linking to it) to determine if it’s a good match for your query.
However, before learning any of that, it's important that you get a lay of the land, so to speak. If you truly want to understand the field of internet marketing, Sharpe has some very good points. In essence there are four overall steps to really understanding internet marketing and leveraging the industry to make money online. Depending on where you are with your education, you'll be somewhere along the lines of these four steps.
Unfortunately, SEO is also a slow process. You can make “quick wins” in markets which are ill-established using SEO, but the truth is that the vast majority of useful keyphrases (including long-tail keyphrases) in competitive markets will already have been optimized for. It is likely to take a significant amount of time to get to a useful place in search results for these phrases. In some cases, it may take months or even years of concentrated effort to win the battle for highly competitive keyphrases.
Such an enlightening post! Thanks for revealing those sources, Brian. This really has opened up my mind to the new ideas. I have read many articles about SEO, especially the ones in my country, most of them don’t really tell how to increase your presence in search engines. But today I found this page, which gave me much more valuable insights. Definitely going to try your tips..
If (a) is correct that looks like bad news for webmasters, BUT if (b) is also correct then – because PR is ultimately calculated over the whole of the web – every page loses out relative to every other page. In other words, there is less PR on the web as a whole and, after a sufficient number of iterations in the PR calculation, normality is restored. Is this correct?

I am not worried by this; I do agree with Danny Sullivan (Great comment Danny, best comment I have read in a long time). I will not be changing much on my site re: linking but it is interesting too see that Google took over a year to tell us regarding the change, but was really happy to tell us about rel=”nofollow” in the first place and advised us all to use it.

An aesthetically pleasing and informational website is an excellent anchor that can easily connect to other platforms like social networking pages and app downloads. It's also relatively simple to set up a blog within the website that uses well-written content with “keywords” an Internet user is likely to use when searching for a topic. For example, a company that wants to market its new sugar-free energy drink could create a blog that publishes one article per week that uses terms like “energy drink,” “sugar-free,” and “low-calorie” to attract users to the product website.
As Google becomes more and more sophisticated, one of the major cores of their algorithm, the one dealing with links (called Penguin) aims to value natural, quality links and devalue those unnatural or spammy ones. As a search engine, if they are to stay viable, they have to make sure their results are as honest and high-quality as possible, and that webmasters can't manipulate those results to their own benefit.
All in all, PageRank sculpting (or whatever we should call it) didn’t really rule my world. But, I did think that it was a totally legitimate method to use. Now that we know the ‘weight’ leaks, this will put a totally new (and more damaging) spin on things. Could we not have just left the ‘weight’ with the parent page? This is what I thought would happen most of the time anyway.
How many times do we need to repeat the calculation for big networks? That’s a difficult question; for a network as large as the World Wide Web it can be many millions of iterations! The “damping factor” is quite subtle. If it’s too high then it takes ages for the numbers to settle, if it’s too low then you get repeated over-shoot, both above and below the average - the numbers just swing about the average like a pendulum and never settle down.
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.

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.
Changes to the algorithms that produce search engine rankings can place a heightened focus on relevance to a particular topic. While some backlinks might be from sources containing highly valuable metrics, they could also be unrelated to the consumer's query or interest. An example of this would be a link from a popular shoe blog (with valuable metrics) to a site selling vintage pencil sharpeners. While the link appears valuable, it provides little to the consumer in terms of relevance.
PageRank is a link analysis algorithm and it assigns a numerical weighting to each element of a hyperlinked set of documents, such as the World Wide Web, with the purpose of "measuring" its relative importance within the set. The algorithm may be applied to any collection of entities with reciprocal quotations and references. The numerical weight that it assigns to any given element E is referred to as the PageRank of E and denoted by {\displaystyle PR(E).} Other factors like Author Rank can contribute to the importance of an entity.
