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.

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.

SEO is a marketing discipline focused on growing visibility in organic (non-paid) search engine results. SEO encompasses both the technical and creative elements required to improve rankings, drive traffic, and increase awareness in search engines. There are many aspects to SEO, from the words on your page to the way other sites link to you on the web. Sometimes SEO is simply a matter of making sure your site is structured in a way that search engines understand.

I started taking action right away on the “Best Of” Blog Posts” approach… I found some great blogs and left a relevant and useful comment. The first impression, sins a lot of the blogs see my as the competition it is not easy to get past the moderator. I made 6 or 7 comments the first day and will update this comment after I have a good number of post to measure results…

This year, for the first time, Google stated that user experience would be a core part of gaining rankings for mobile websites. A poorer user experience would send your site hurtling down the rankings. This appeared to come as a shock to many in the SEO community and despite assurances that content was still king – many seemed to feel that this ...
This will help you replicate their best backlinks and better understand what methods they are using to promote their website. If they are getting links through guest blogging, try to become a guest author on the same websites. If most of their links come from blog reviews, get in touch with those bloggers and offer them a trial to test your tool. Eventually, they might write a review about it.

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.
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.
Search queries—the words that users type into the search box—carry extraordinary value. Experience has shown that search engine traffic can make (or break) an organization's success. Targeted traffic to a website can provide publicity, revenue, and exposure like no other channel of marketing. Investing in SEO can have an exceptional rate of return compared to other types of marketing and promotion.

What is a useful place in search results? Ideally, you need to be in the top three search results returned. More than 70% of searches are resolved in these three results, while 90% are resolved on the first page of results. So, if you’re not in the top three, you’re going to find you’re missing out on the majority of potential business—and if you’re not on the first page, you’re going to miss out on nearly all potential business.

On another note, I would like to express my contempt for Google and its so called terms of service regarding the legitimate acquisition of links. why should it care if links are paid for or not? Thanks to the invention of pagerank, it is Google itself that has cancelled out reciprocal linking and has stopped people giving out links due to fear of them losing pagerank, and blogs and forums are worthless thanks to the nofollow trick. so it is now impossible to get decent links organically, without having to pay for them, and those who do give out free links are considered fools. Google has brought this dilemma on itself, and yet it seems like punishing us for trying to get links other than freely! Face facts, no one is going to link to someone without getting a link in return! google has invented pagerank which is like a currency, and so people expect to be paid for links, as giving out links devalues their pagerank and so compensation is now required. It is forcing people to use underhand methods to get links, mostly the ‘paid’ variety.
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.
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]
3. General on-site optimization. On-site optimization is a collection of tactics, most of which are simple to implement, geared toward making your website more visible and indexable to search engines. These tactics include things like optimizing your titles and meta descriptions to include some of your target keywords, ensuring your site’s code is clean and minimal, and providing ample, relevant content on every page. I’ve got a huge list of on-site SEO tactics you can check out here.
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]

Google PageRank algorithm takes into consideration the sources and the number of web page backlinks, then estimates the importance of that page. That is why when you try to search for some goods, information or service, Google and other search engines present website links in a concrete order (from the most valuable to the least important ones). Backlinks help your website attract a primary audience.

As of 2009, there are only a few large markets where Google is not the leading search engine. In most cases, when Google is not leading in a given market, it is lagging behind a local player. The most notable example markets are China, Japan, South Korea, Russia and the Czech Republic where respectively Baidu, Yahoo! Japan, Naver, Yandex and Seznam are market leaders.

@matt: I notice a bit of WordPress-related talk early in the comments (sorry, Dont have time to read all of them right now..), I was wondering if you’d like to comment on Trac ticket(http://core.trac.wordpress.org/ticket/10550) – Related to the use of nofollow on non-js-fallback comment links which WordPress uses – Its linking to the current page with a changed form.. the content and comments should remain the same, just a different form.. I think the original reason nofollow was added there was to prevent search engines thinking the site was advertising multiple pages with the same content..
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.
