The formula uses a model of a random surfer who gets bored after several clicks and switches to a random page. The PageRank value of a page reflects the chance that the random surfer will land on that page by clicking on a link. It can be understood as a Markov chain in which the states are pages, and the transitions, which are all equally probable, are the links between pages.


SERPs typically contain two types of content – “organic” results and paid results. Organic results are listings of web pages that appear as a result of the search engine’s algorithm (more on this shortly). Search engine optimization professionals, commonly known as SEOs, specialize in optimizing web content and websites to rank more highly in organic search results.

First, let me explain in more detail why the values shown in the Google toolbar are not the actual PageRank figures. According to the equation, and to the creators of Google, the billions of pages on the web average out to a PageRank of 1.0 per page. So the total PageRank on the web is equal to the number of pages on the web * 1, which equals a lot of PageRank spread around the web.


PageRank was influenced by citation analysis, early developed by Eugene Garfield in the 1950s at the University of Pennsylvania, and by Hyper Search, developed by Massimo Marchiori at the University of Padua. In the same year PageRank was introduced (1998), Jon Kleinberg published his work on HITS. Google's founders cite Garfield, Marchiori, and Kleinberg in their original papers.[5][17]

Now you know the difference between impressions and Impression Share (IS). Regularly monitor your Impression Share metrics and quickly fix issues as they arise. Low Impression Share hurts your chances at success by allowing your competitors to gain greater market share. Chances are, your competitors are already closely monitoring their IS and actively optimizing to 100% Impression Share. PPC is a dynamic platform – always look for opportunities to make gains over your competitors.

It’s good for searchers – Research indicates that searchers click on paid search ads more often than any other form of digital advertising. This means that people really don’t mind being advertised to, provided that the products and services advertised actually fit the searcher’s needs. And because we use search engines when we’re looking for products and services, the results, including the ads, are generally highly relevant to what we’re looking for. Plus, Google has developed an excellent formula for ensuring that PPC ads meet the user’s needs.
In my experience, a common challenge is where to start drawing up your digital marketing plan. I think there is a fear that a massive report is required, but we believe that lean planning works best. Your plan doesn't need to be a huge report, a strategy can best be summarized in two or three sides of A4 in a table linking digital marketing strategies to SMART objectives within our RACE planning framework. We recommend creating a lean digital plan based on our 90-day planning templates to implement your digital plan rapidly to gain traction. You can learn more in our free download.

In both cases the total PageRank in the site is 3 (the maximum) so none is being wasted. Also in both cases you can see that page A has a much larger proportion of the PageRank than the other 2 pages. This is because pages B and C are passing PageRank to A and not to any other pages. We have channeled a large proportion of the site’s PageRank to where we wanted it.
The content page in this figure is considered good for several reasons. First, the content itself is unique on the Internet (which makes it worthwhile for search engines to rank well) and covers a specific bit of information in a lot of depth. If a searcher had question about Super Mario World, there is a good chance, that this page would answer their query.
The process of harvesting search engine result pages data is usually called "search engine scraping" or in a general form "web crawling" and generates the data SEO related companies need to evaluate website competitive organic and sponsored rankings. This data can be used to track the position of websites and show the effectiveness of SEO as well as keywords that may need more SEO investment to rank higher.
The default page of Google’s search result is a page on which different results appear. Google decides which results fit your search query best. That could be ‘normal’ results, but also news results, shopping results or images. If you’re searching for information, a knowledge graph could turn up. When you’re searching to buy something online, you’ll probably get lots of shopping results on the default result page.
You should optimize your site to serve your users' needs. One of those users is a search engine, which helps other users discover your content. Search Engine Optimization is about helping search engines understand and present content. Your site may be smaller or larger than our example site and offer vastly different content, but the optimization topics we discuss below should apply to sites of all sizes and types. We hope our guide gives you some fresh ideas on how to improve your website, and we'd love to hear your questions, feedback, and success stories in the Google Webmaster Help Forum1.
As mobile devices become an increasingly integral part of our lives, it’s vital that marketers understand how to effectively communicate on this unique and extremely personal channel. Mobile devices are kept in our pockets, sit next to our beds, and are checked constantly throughout the day. This makes marketing on mobile incredibly important but also very nuanced.
Guest Blogging: although this practice has been discredited due to the generation of poor quality articles, which have become spam (since they were used only to promote links), Google has failed to encourage this tactic. But, if you can ensure that you can create a high-quality guest post, that’s relevant to the context of your area, then go ahead.

There are lots of ways you can optimize your digital marketing assets for mobile users, and when implementing any digital marketing strategy, it's hugely important to consider how the experience will translate on mobile devices. By ensuring this is always front-of-mind, you'll be creating digital experiences that work for your audience, and consequently achieve the results you're hoping for.


This URL clearly shows the hierarchy of the information on the page (history as it pertains to video games in the context of games in general). This information is used to determine the relevancy of a given web page by the search engines. Due to the hierarchy, the engines can deduce that the page likely doesn’t pertain to history in general but rather to that of the history of video games. This makes it an ideal candidate for search results related to video game history. All of this information can be speculated on without even needing to process the content on the page.
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.

There are a number of ways brands can use digital marketing to benefit their marketing efforts. The use of digital marketing in the digital era not only allows for brands to market their products and services, but also allows for online customer support through 24/7 services to make customers feel supported and valued. The use of social media interaction allows brands to receive both positive and negative feedback from their customers as well as determining what media platforms work well for them. As such, digital marketing has become an increased advantage for brands and businesses. It is now common for consumers to post feedback online through social media sources, blogs and websites on their experience with a product or brand.[25] It has become increasingly popular for businesses to use and encourage these conversations through their social media channels to have direct contact with the customers and manage the feedback they receive appropriately.
An SEO technique is considered white hat if it conforms to the search engines' guidelines and involves no deception. As the search engine guidelines[18][19][51] are not written as a series of rules or commandments, this is an important distinction to note. White hat SEO is not just about following guidelines, but is about ensuring that the content a search engine indexes and subsequently ranks is the same content a user will see. White hat advice is generally summed up as creating content for users, not for search engines, and then making that content easily accessible to the online "spider" algorithms, rather than attempting to trick the algorithm from its intended purpose. White hat SEO is in many ways similar to web development that promotes accessibility,[52] although the two are not identical.
