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.
Ian Rogers first used the Internet in 1986 sending email on a University VAX machine! He first installed a webserver in 1990, taught himself HTML and perl CGI scripting. Since then he has been a Senior Research Fellow in User Interface Design and a consultant in Network Security and Database Backed Websites. He has had an informal interest in topology and the mathematics and behaviour of networks for years and has also been known to do a little Jive dancing.
The criteria and metrics can be classified according to its type and time span. Regarding the type, we can either evaluate these campaigns "Quantitatively" or "Qualitatively". Quantitative metrics may include "Sales Volume" and "Revenue Increase/Decrease". While qualitative metrics may include the enhanced "Brand awareness, image and health" as well as the "relationship with the customers".
Totally agree — more does not always equal better. Google takes a sort of ‘Birds of a Feather’ approach when analyzing inbound links, so it’s really all about associating yourself (via inbound links) with websites Google deems high quality and trustworthy so that Google deems YOUR web page high quality and trustworthy. As you mentioned, trying to cut corners, buy links, do one-for-one trades, or otherwise game/manipulate the system never works. The algorithm is too smart.
138. Direct Traffic: It’s confirmed that Google uses data from Google Chrome to determine how many people visit site (and how often). Sites with lots of direct traffic are likely higher quality sites vs. sites that get very little direct traffic. In fact, the SEMRush study I just cited found a significant correlation between direct traffic and Google rankings.
Every time a search is initiated, Google digs into the pool of bidding AdWords advertisers and chooses a set of winners to appear in the ad space on its search results page. The “winners” are chosen based on a combination of factors, including the quality and relevance of their keywords and ad text, as well as the size of their keyword bids. For example, if WordStream bid on the keyword “PPC software,” our ad might show up in the very top spot on the Google results page.
Search results are presented in an ordered list, and the higher up on that list a site can get, the more traffic the site will tend to receive. For example, for a typical search query, the number one result will receive 40-60% of the total traffic for that query, with the number two and three results receiving significantly less traffic. Only 2-3% of users click beyond the first page of search results.
The box on the right side of this SERP is known as the Knowledge Graph (also sometimes called the Knowledge Box). This is a feature that Google introduced in 2012 that pulls data to commonly asked questions from sources across the web to provide concise answers to questions in one central location on the SERP. In this case, you can see a wide range of information about Abraham Lincoln, such as the date and place of his birth, his height, the date on which he was assassinated, his political affiliation, and the names of his children – many of which facts have their own links to the relevant pages.
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.
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)

For search engine optimization purposes, some companies offer to sell high PageRank links to webmasters. 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.
It is easy to think of our site as being a small, self-contained network of pages. When we do the PageRank calculations we are dealing with our small network. If we make a link to another site, we lose some of our network’s PageRank, and if we receive a link, our network’s PageRank is added to. But it isn’t like that. For the PageRank calculations, there is only one network – every page that Google has in its index. Each iteration of the calculation is done on the entire network and not on individual websites.
With the advent of portable devices, smartphones, and wearable devices, watches and various sensors, these provide ever more contextual dimensions for consumer and advertiser to refine and maximize relevancy using such additional factors that may be gleaned like: a person's relative health, wealth, and various other status, time of day, personal habits, mobility, location, weather, and nearby services and opportunities, whether urban or suburban, like events, food, recreation, and business. Social context and crowd sourcing influences can also be pertinent factors.
PPC is an advertising method a company executes by placing paid text or display advertisements on search engine web results pages or website pages. The owner of the ad pays a fee to the host website or search engine, through the advertising management platform, when web users click the ad. Each click will open up your business profile, website, goods or services to the visitor. In essence, you are “buying” visitors who may become clients.
Now imagine you had that brochure on your website instead. You can measure exactly how many people viewed the page where it's hosted, and you can collect the contact details of those who download it by using forms. Not only can you measure how many people are engaging with your content, but you're also generating qualified leads when people download it.
SEO is not an appropriate strategy for every website, and other Internet marketing strategies can be more effective like paid advertising through pay per click (PPC) campaigns, depending on the site operator's goals. Search engine marketing (SEM), is practice of designing, running, and optimizing search engine ad campaigns. Its difference from SEO is most simply depicted as the difference between paid and unpaid priority ranking in search results. Its purpose regards prominence more so than relevance; website developers should regard SEM with the utmost importance with consideration to PageRank visibility as most navigate to the primary listings of their search. A successful Internet marketing campaign may also depend upon building high quality web pages to engage and persuade, setting up analytics programs to enable site owners to measure results, and improving a site's conversion rate. In November 2015, Google released a full 160 page version of its Search Quality Rating Guidelines to the public, which now shows a shift in their focus towards "usefulness" and mobile search. In recent years the mobile market has exploded, overtaking the use of desktops as shown in by StatCounter in October 2016 where they analysed 2.5 million websites and 51.3% of the pages were loaded by a mobile device . Google has been one of the companies that have utilised the popularity of mobile usage by encouraging websites to use their Google Search Console, the Mobile-Friendly Test, which allows companies to measure up their website to the search engine results and how user-friendly it is.
Links - Links from other websites play a key role in determining the ranking of a site in Google and other search engines. The reason being, a link can be seen as a vote of quality from other websites, since website owners are unlikely to link to other sites which are of poor quality. Sites that acquire links from many other sites gain authority in the eyes of search engines, especially if the sites that are linking to them are themselves authoritative.
Digital marketing and its associated channels are important – but not to the exclusion of all else. It’s not enough to just know your customers; you must know them better than anybody else so you can communicate with them where, when and how they are most receptive to your message. To do that, you need a consolidated view of customer preferences and expectations across all channels – Web, social media, mobile, direct mail, point of sale, etc. Marketers can use this information to create and anticipate consistent, coordinated customer experiences that will move customers along in the buying cycle. The deeper your insight into customer behavior and preferences, the more likely you are to engage them in lucrative interactions.
It is not a good idea for one page to link to a large number of pages so, if you are adding many new pages, spread the links around. The chances are that there is more than one important page in a site, so it is usually suitable to spread the links to and from the new pages. You can use the calculator to experiment with mini-models of a site to find the best links that produce the best results for its important pages.
While most of the links to your site will be added gradually, as people discover your content through search or other ways and link to it, Google understands that you'd like to let others know about the hard work you've put into your content. Effectively promoting your new content will lead to faster discovery by those who are interested in the same subject. As with most points covered in this document, taking these recommendations to an extreme could actually harm the reputation of your site.

Going back to our bicycle shop example: At this point, we’re ready to cancel our PPC account and never look back. But we dig a bit deeper, and notice that customers acquired from our PPC campaign spend another $800 each, per year, on higher-margin items that deliver an average profit of $200 per sale – we’re getting loyal, long-term business. That changes the picture significantly:
Organic SERP listings are the natural listings generated by search engines based on a series of metrics that determines their relevance to the searched term. Webpages that score well on a search engine's algorithmic test show in this list. These algorithms are generally based upon factors such as the content of a webpage, the trustworthiness of the website, and external factors such as backlinks, social media, news, advertising, etc.
In 2005, in a pilot study in Pakistan, Structural Deep Democracy, SD2 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.
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.
Although GoTo.com started PPC in 1998, Yahoo! did not start syndicating GoTo.com (later Overture) advertisers until November 2001. Prior to this, Yahoo's primary source of SERPS advertising included contextual IAB advertising units (mainly 468x60 display ads). When the syndication contract with Yahoo! was up for renewal in July 2003, Yahoo! announced intent to acquire Overture for $1.63 billion. Today, companies such as adMarketplace, ValueClick and adknowledge offer PPC services, as an alternative to AdWords and AdCenter.
 Matteo Pasquinelli reckons the basis for the belief that PageRank has a social component lies in the idea of attention economy. With attention economy, value is placed on products that receive a greater amount of human attention and the results at the top of the PageRank garner a larger amount of focus then those on subsequent pages. The outcomes with the higher PageRank will therefore enter the human consciousness to a larger extent. These ideas can influence decision-making and the actions of the viewer have a direct relation to the PageRank. They possess a higher potential to attract a user’s attention as their location increases the attention economy attached to the site. With this location they can receive more traffic and their online marketplace will have more purchases. The PageRank of these sites allow them to be trusted and they are able to parlay this trust into increased business.
If the value of a lead or engagement is a bit unclear, I recommend you take a close look at the lifetime value (LTV) of your customers. Don’t just think about how much profit they’ll bring in on the first sale, consider how much your average customer spends over the lifetime of their relationship with you. Compare this against your conversion rate and you’ll be able to better assess how much you can afford to bid.
Your entire PPC campaign is built around keywords, and the most successful AdWords advertisers continuously grow and refine their PPC keyword list (ideally, using a variety of tools, not just Keyword Planner). If you only do keyword research once, when you create your first campaign, you are probably missing out on hundreds of thousands of valuable, long-tail, low-cost and highly relevant keywords that could be driving traffic to your site.
Size: (green) The size of the text portion of the web page. It is omitted for sites not yet indexed. In the screen shot, “5k” means that the text portion of the web page is 5 kilobytes. One kilobyte is 1,024 (210) bytes. One byte typically holds one character. In general, the average size of a word is six characters. So each 1k of text is about 170 words. A page containing 5K characters thus is about 850 words long.
Optimization techniques are highly tuned to the dominant search engines in the target market. The search engines' market shares vary from market to market, as does competition. In 2003, Danny Sullivan stated that Google represented about 75% of all searches. In markets outside the United States, Google's share is often larger, and Google remains the dominant search engine worldwide as of 2007. As of 2006, Google had an 85–90% market share in Germany. While there were hundreds of SEO firms in the US at that time, there were only about five in Germany. As of June 2008, the marketshare of Google in the UK was close to 90% according to Hitwise. That market share is achieved in a number of countries.
