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.

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.
It is increasingly advantageous for companies to use social media platforms to connect with their customers and create these dialogues and discussions. The potential reach of social media is indicated by the fact that in 2015, each month the Facebook app had more than 126 million average unique users and YouTube had over 97 million average unique users.[27]

Also hadn’t thought about decreasing the rank value based on the spammyness of sites a page is linking into. My guess on how to do it would be determining the spammyness of individual pages based on multiple page and site factors, then some type of reverse pagerank calcuation starting with the those bad scores, then overlaying that on top of the “good” pagerank calculation as a penalty. This is another thing which would be interesting to play around with in the Nutch algorithm.
The SEO starter guide describes much of what your SEO will do for you. Although you don't need to know this guide well yourself if you're hiring a professional to do the work for you, it is useful to be familiar with these techniques, so that you can be aware if an SEO wants to use a technique that is not recommended or, worse, strongly discouraged.
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.
Great Post, I am agree with you. currently Google keeps change in algorithmic program methods thus in gift state of affairs everybody ought to have an honest quality website, quality content. Content is quality {and ought to|and will|and may} be contemporary on your web site and conjointly it should be associated with the subject. it’ll assist you in your ranking.

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.

A search engine considers the content of the sites to determine the QUALITY of a link. When inbound links to your site come from other sites, and those sites have content related to your site, these inbound links are considered more relevant to your site. If inbound links are found on sites with unrelated content, they are considered less relevant. The higher the relevance of inbound links, the greater their quality.
Display advertising - As the term infers, Online Display Advertisement deals with showcasing promotional messages or ideas to the consumer on the internet. This includes a wide range of advertisements like advertising blogs, networks, interstitial ads, contextual data, ads on the search engines, classified or dynamic advertisement etc. The method can target specific audience tuning in from different types of locals to view a particular advertisement, the variations can be found as the most productive element of this method.

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.
In my example, if I am passing PR to a local eatery by having a do-follow link but there are 9 nofollow links on that page and I only had 10 points to begin with then that lowers the value I can give from my local foodie blog to that site. In that case would it actually be better to either disallow comments on that page or to disallow links associated with the comments on that page? I mean if my client is a food blogger (and some are) and they tell the restaurateur “when I write about you it will be good for your Google juice because I will place a link to you with my post” then they would really be diminishing the value they could give by having an increased number of links. Kinds of sucks for the blogger who wants a lot of comments, no?
In this illustration from the “PageRank Citation Ranking” paper, the authors demonstrate how webpages pass value onto other pages. The two pages on the left have a value of 100 and 9, respectively. The page with a value of 100 has two links that point to the pages on the right. That page’s value of 100 is divided between the two links, so that each conveys a value of 50. The other page on the left has three outgoing links, each carrying one-third of the page’s value of 9. One link goes to the top page on the right, which ends up with a total value of 53. The bottom right page has no other backlinks, so its total value is 50.

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.
My final (thank goodness) point on this is not that (white hat) PageRank sculpitng was really anything special. It was just quite logical. It really feels like we are going down a wrong route here. Shall we outlaw cars because some people drive dangerously? Or should we do all we can to make driving safer? Not on the same level in any way, but you can see my point here. This is the first time I have felt that you have made a bad call and that is the only reason I am making a case for the logics of this.
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.

At one point, backlinks developed a reputation of damaging a site’s credibility through search engines. This is due to “black hat” SEO practices would add 5,000 links to a website overnight (a practice that is still used today). While the website would launch to the top of search ranking results for a few weeks, it wouldn’t stay there, and the site’s credibility would be damaged because a few dozen servers with thousands of useless websites existed for the sole purpose of creating backlinks.

Steve, sometimes good information to users is a consolidation of very high quality links. We have over 3000 links to small business sites within the SBA as well as links to the Harvard and Yale library, academic journals, etc. But because we have the understanding that there should be no more than a hundred links in a website (more now from what Matt said) we have used nofollow on all of them out of fear that Google will penalize our site because of the amount of links.

Donating your time or money to local charities, organizations, and schools is actually a great - yet often overlooked - way of obtaining backlinks. Such organizations often have pages where they promote sponsors and donors, giving you the opportunity to net a backlink from a trusted organization. If such an organization has a donors section on their homepage, that's even better!
A variety of methods can increase the prominence of a webpage within the search results. Cross linking between pages of the same website to provide more links to important pages may improve its visibility.[47] Writing content that includes frequently searched keyword phrase, so as to be relevant to a wide variety of search queries will tend to increase traffic.[47] Updating content so as to keep search engines crawling back frequently can give additional weight to a site. Adding relevant keywords to a web page's meta data, including the title tag and meta description, will tend to improve the relevancy of a site's search listings, thus increasing traffic. URL canonicalization of web pages accessible via multiple urls, using the canonical link element[48] or via 301 redirects can help make sure links to different versions of the url all count towards the page's link popularity score.
So, the probability for the random surfer reaching one page is the sum of probabilities for the random surfer following links to this page. Now, this probability is reduced by the damping factor d. The justification within the Random Surfer Model, therefore, is that the surfer does not click on an infinite number of links, but gets bored sometimes and jumps to another page at random.
Thanks Matt for the informative post. However I do have some questions regarding blog comments. Let say a blog post of mine have PR 10, the page has 10 links, 3 of them are my internal link to my other related post, the other 7 links are external links from blog comment. Based on your explanation, even the 7 external links are nofollow, my 3 internal link will only get 1 PR each which is still the same if the 7 external link is dofollow. Therefore there is no point of adding nofollow for the sake of keeping the PR flow within your own links. Is this correct?
Content is king. Your content needs to be written so that it provides value to your audience. It should be a mix of long and short posts on your blog or website. You should not try to “keyphrase stuff” (mentioning a keyphrase over and over again to try and attract search engines) as this gets penalized by search engines now. However, your text should contain the most important keyphrases at least once and ideally two to three times—ideally, it should appear in your title. However, readability and value are much more important than keyword positioning today.
Conversion rate optimization is all about testing. Many companies get too bogged down in design and what they think looks best and will convert. At the end of the day, you don’t know until you test. At IMI, we have the tools, technology, and expertise to not only build well-optimized web pages but to test them once they go live. Our conversion rate optimization can not only save our client’s money but generate millions in revenue.
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 whole thing is super user friendly. The UI is insanely great and intuitive. The Dashboard really does give you all the information you are seeking in one place and is perfectly built to show correlation in your efforts. I also like that I don't have to use 3 different tools and I have the info I need in one place. Competitor tracking is definitely a plus. But if I had to pinpoint the biggest USP it would be the use experience. Everyone I recommend this tool too says how great it looks, how easy it is to use, and how informative the information is. You guys hit the mark by keeping it simple, and sticking to providing only the necessary information. Sorry for the ramble, but I love this tool and will continue to recommend it.

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!
Search engine optimization (SEO) is often about making small modifications to parts of your website. When viewed individually, these changes might seem like incremental improvements, but when combined with other optimizations, they could have a noticeable impact on your site's user experience and performance in organic search results. You're likely already familiar with many of the topics in this guide, because they're essential ingredients for any web page, but you may not be making the most out of them.
Description meta tags are important because Google might use them as snippets for your pages. Note that we say "might" because Google may choose to use a relevant section of your page's visible text if it does a good job of matching up with a user's query. Adding description meta tags to each of your pages is always a good practice in case Google cannot find a good selection of text to use in the snippet. The Webmaster Central Blog has informative posts on improving snippets with better description meta tags18 and better snippets for your users19. We also have a handy Help Center article on how to create good titles and snippets20. 

You should fix all errors which can impair users’ expectations. By hurting user experience, you endanger the organic growth of your traffic because Google will surely limit it. Do this task thoroughly and don’t be in a hurry, otherwise, you might learn that your backlinks don’t work. Be responsible for each decision and action. Search Engine Optimization (SEO) works better when the technical optimization of your site meets the standards.
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.
Retargeting is another way that we can close the conversion loop and capitalize on the traffic gained from the overall marketing campaign. Retargeting is a very powerful display advertising tool to keep your brand top of mind and keep them coming back. We track every single touch point up to the ultimate conversions and use that data to make actionable recommendations for further campaign optimization.
If Google finds two identical pieces of content, whether on your own site, or on another you’re not even aware of, it will only index one of those pages. You should be aware of scraper sites, stealing your content automatically and republishing as your own. Here’s Graham Charlton’s thorough investigation on what to if your content ends up working better for somebody else.
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.
PageRank was developed by Google founders Larry Page and Sergey Brin at Stanford. In fact the name. PageRank is a likely play on Larry Page's name. At the time that Page and Brin met, early search engines typically linked to pages that had the highest keyword density, which meant people could game the system by repeating the same phrase over and over to attract higher search page results. Sometimes web designers would even put hidden text on pages to repeat phrases.
