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]
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.

This section can be summed up in two words: GO BIG. “Blocking and Tackling” is a phrase that emphasizes the need to excel at fundamentals. We covered many PPC marketing fundamentals in the first two segments and it is important to note that you should always strive to block and tackle your way to success. However, don’t let the routine of blocking and tackling impede your creative and innovative side. Constantly remind yourself that end goal is customer acquisition (and your ongoing challenge) is to constantly build a better mousetrap.

The green ratings bars are a measure of the importance Google’s assessment of the importance of a web page, as determined by Google’s patented PageRank technology and other factors. These PageRank bars tell you at a glance whether other people on the web consider Google considers a page to be a high-quality site worth checking out. Google itself does not evaluate or endorse websites. Rather, we measure what others on the web feel is important enough to deserve a link. And because Google does not accept payment for placement within our results, the information you see when you conduct a search is based on totally objective criteria.
Despite this many people seem to get it wrong! In particular “Chris Ridings of www.searchenginesystems.net” has written a paper entitled “PageRank Explained: Everything you’ve always wanted to know about PageRank”, pointed to by many people, that contains a fundamental mistake early on in the explanation! Unfortunately this means some of the recommendations in the paper are not quite accurate.
You may not want certain pages of your site crawled because they might not be useful to users if found in a search engine's search results. If you do want to prevent search engines from crawling your pages, Google Search Console has a friendly robots.txt generator to help you create this file. Note that if your site uses subdomains and you wish to have certain pages not crawled on a particular subdomain, you'll have to create a separate robots.txt file for that subdomain. For more information on robots.txt, we suggest this Webmaster Help Center guide on using robots.txt files13.
For the examples, we are going to ignore that fact, mainly because other ‘Pagerank Explained’ type documents ignore it in the calculations, and it might be confusing when comparing documents. The calculator operates in two modes:- Simple and Real. In Simple mode, the calculations assume that all pages are in the Google index, whether or not any other pages link to them. In Real mode the calculations disregard unlinked-to pages. These examples show the results as calculated in Simple mode. pagerank, page rank

On-page SEO refers to best practices that web content creators and site owners can follow to ensure their content is as easily discoverable as possible. This includes the creation of detailed page metadata (data about data) for each page and elements such as images, the use of unique, static URLs, the inclusion of keywords in relevant headings and subheadings, and the use of clean HTML code, to name a few.
Another reason is that if you're using an image as a link, the alt text for that image will be treated similarly to the anchor text of a text link. However, we don't recommend using too many images for links in your site's navigation when text links could serve the same purpose. Lastly, optimizing your image filenames and alt text makes it easier for image search projects like Google Image Search to better understand your images.
A Web crawler may use PageRank as one of a number of importance metrics it uses to determine which URL to visit during a crawl of the web. One of the early working papers [54] that were used in the creation of Google is Efficient crawling through URL ordering,[55] which discusses the use of a number of different importance metrics to determine how deeply, and how much of a site Google will crawl. PageRank is presented as one of a number of these importance metrics, though there are others listed such as the number of inbound and outbound links for a URL, and the distance from the root directory on a site to the URL.
To answer your question, David, take a look at Jim’s comment below. Yes, you can and SHOULD optimize PR by directing link equity at important pages and internally linking within a theme. PageRank is a core part of the Google ranking algo. We don’t get visibility into PageRank as a number or score, but you need to know about the concept in order to direct your internal, strategic linking and navigation.

So, digital marketing is about utilizing digital technology to achieve marketing objectives. There is no essential need for digital marketing to always be separate from the marketing department as a whole, as the objectives of both are the same. However, for now, it remains a useful term because digital marketing requires a certain skill set to utilize the digital technology effectively.


Imagine the page, www.domain.com/index.html. The index page contains links to several relative urls; e.g. products.html and details.html. The spider sees those urls as www.domain.com/products.html and www.domain.com/details.html. Now let’s add an absolute url for another page, only this time we’ll leave out the “www.” part – domain.com/anotherpage.html. This page links back to the index.html page, so the spider sees the index pages as domain.com/index.html. Although it’s the same index page as the first one, to a spider, it is a different page because it’s on a different domain. Now look what happens. Each of the relative urls on the index page is also different because it belongs to the domain.com/ domain. Consequently, the link stucture is wasting a site’s potential PageRank by spreading it between ghost pages.
Cross-platform measurement: The number of marketing channels continues to expand, as measurement practices are growing in complexity. A cross-platform view must be used to unify audience measurement and media planning. Market researchers need to understand how the Omni-channel affects consumer's behaviour, although when advertisements are on a consumer's device this does not get measured. Significant aspects to cross-platform measurement involves de-duplication and understanding that you have reached an incremental level with another platform, rather than delivering more impressions against people that have previously been reached (Whiteside, 2016).[42] An example is ‘ESPN and comScore partnered on Project Blueprint discovering the sports broadcaster achieved a 21% increase in unduplicated daily reach thanks to digital advertising’ (Whiteside, 2016).[42] Television and radio industries are the electronic media, which competes with digital and other technological advertising. Yet television advertising is not directly competing with online digital advertising due to being able to cross platform with digital technology. Radio also gains power through cross platforms, in online streaming content. Television and radio continue to persuade and affect the audience, across multiple platforms (Fill, Hughes, & De Franceso, 2013).[45]
Unlike most offline marketing efforts, digital marketing allows marketers to see accurate results in real time. If you've ever put an advert in a newspaper, you'll know how difficult it is to estimate how many people actually flipped to that page and paid attention to your ad. There's no surefire way to know if that ad was responsible for any sales at all.
The role of a social media manager is easy to infer from the title, but which social networks they manage for the company depends on the industry. Above all, social media managers establish a posting schedule for the company's written and visual content. This employee might also work with the content marketing specialist to develop a strategy for which content to post on which social network.
The Digital Marketing course takes a holistic view of digital marketing, whilst really focusing on the more quantitative and data-driven aspects of contemporary marketing. You’ll be pushed to gain a clear understanding of a business’ goals and brand voice in order to launch a truly effective marketing campaign. Students will learn how to utilize analytics in order to make data-driven decisions ranging from audience segmentation and targeting, to what content resonates best with users.
Brand awareness has been proven to work with more effectiveness in countries that are high in uncertainty avoidance, also these countries that have uncertainty avoidance; social media marketing works effectively. Yet brands must be careful not to be excessive on the use of this type of marketing, as well as solely relying on it as it may have implications that could negatively harness their image. Brands that represent themselves in an anthropomorphizing manner are more likely to succeed in situations where a brand is marketing to this demographic. "Since social media use can enhance the knowledge of the brand and thus decrease the uncertainty, it is possible that people with high uncertainty avoidance, such as the French, will particularly appreciate the high social media interaction with an anthropomorphized brand." Moreover, digital platform provides an ease to the brand and its customers to interact directly and exchange their motives virtually.[33]

All major crawler-based search engines leverage links from across of the web, but none of them report a static “importance” score in the way Google does via its Google Toolbar. That score, while a great resource for surfers, has also provided one of the few windows into how Google ranks web pages. Some webmasters, desperate to get inside Google, keep flying into that window like confused birds, smacking their heads and losing their orientation….
Say you're running a PPC ad for the keyword "Nikon D90 digital camera" -- a product you sell on your website. You set up the ad to run whenever this keyword is searched for on your chosen engine, and you use a URL that redirects readers who click on your ad to your site's home page. Now, this user must painstakingly click through your website's navigation to find this exact camera model -- if he or she even bothers to stick around.
Trust is another important bucket that you need to be aware of when you are trying to get your site to rank in Google. Google doesn’t want to show just any website to it’s searchers, it wants to show the best website to its searchers, and so it wants to show sites that are trustworthy. One thing Google has indicated it likes to do is penalize sites or stores or companies that consistently have poor reviews, so if you have many poor reviews, in time Google is going to figure out not to show your site in their rankings because Google doesn’t want to show those sites to their searchers. So prove to Google’s algorithm that you are trustworthy. Get other highly authoritative websites to link to you. Get newspaper articles, get industry links, get other trusted sites to link to you: partners, vendors, happy customers - get them to link to your website to show that you are highly credible and trustworthy.
“I didn’t realize how much we were missing from not having an online presence until I started working with the SEO firm Brick Marketing. The Brick Marketing team took the time to guide us through the SEO process and helped bring our company into the online world. We’ve seen unbelievable success with our new website & owe much of our online lead generation to Brick Marketing’s efforts.”

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.
By relying so much on factors such as keyword density which were exclusively within a webmaster's control, early search engines suffered from abuse and ranking manipulation. To provide better results to their users, search engines had to adapt to ensure their results pages showed the most relevant search results, rather than unrelated pages stuffed with numerous keywords by unscrupulous webmasters. This meant moving away from heavy reliance on term density to a more holistic process for scoring semantic signals.[13] Since the success and popularity of a search engine is determined by its ability to produce the most relevant results to any given search, poor quality or irrelevant search results could lead users to find other search sources. Search engines responded by developing more complex ranking algorithms, taking into account additional factors that were more difficult for webmasters to manipulate. In 2005, an annual conference, AIRWeb, Adversarial Information Retrieval on the Web was created to bring together practitioners and researchers concerned with search engine optimization and related topics.[14]
