How Google Page Rank Works

Do You Know How Google Page Rank Works?

Page rank is a crucial part of internet technology since it determines how websites, pages and videos are ordered and filed. This form of technology uses link analysis algorithms to determine how relevant a particular site, page or video is related to a particular search term. Link analysis algorithms operates on the principal of relevancy. In other words, if a page has a lot of links connected to it from outside sources then it must be of value to people. While this might seem like a superficial way to evaluate the relevancy of a website, webpage or video; the bottom line is that links play the ultimate role with the position of a webpage when compared to other sites in its category.

Why Does PageRanking Technology Evaluate Links to Determine Page Order in Browsers? 

The World Wide Web is an extremely complex system of computers and information that are connected without boundaries. While it is true that a person can search the internet for just about any topic imaginable; it is also true that they can be given millions of pieces of information on a particular subject. In other words, it would literally take years for a person to search through all off this information just to find the knowledge that they are seeking.

Evaluation of Links by Google

The PageRanking system simply makes it easier for people to find what they need. This way they do not have to look through millions of websites trying to find the most relevant results to their queries.

The creators of the PageRanking technology realized (or decided) that the best way for the internet to present relevant information to “web surfers” is by organizing pages according to the number of links that they have. The more relevant and important that a website is on a particular subject; people will naturally connect to this site for the purpose of credibility and for validating knowledge in a particular area.

Governmental, educational and industry related websites are typically ranked high on a particular subject (or search term) simply because they are authoritative. In other words, people understand that government, education and various business organizations are on the leading edge of knowledge, technology development, policy and law. SInce these institutions are generally viewed as credible and important aspects of society; people will naturally link their sites back to one of these institutions.

Again, they do so for the purpose of credibility and to validate their information. In this sense, PageRanking is no different from journalism. Citing credible sources is an important part of journalism and people use this same approach when they are trying to confirm their information on the web. PageRanking can also be viewed in terms of a vote for a particular website. The more links that a website has increases its relevance and importance.

Keep in mind that people also create links to specific sites to increase their website’s popularity and number of hits. While PageRank primarily evaluates link totals to rank pages, it does not limit itself to just this criteria. Other factors will also determine how a webpage is ranked. If a particular site, page or video has a lot of visitors or hits then the PageRank system will take notice and begin to place a particular web portal higher up on its ranking index.

A perfect example of how this happens in everyday life is when a person releases a very popular video that goes viral. When a video goes viral and it is instantly viewed by millions of people within a matter of days, the PageRanking system will automatically begin to notice the activity. That video will then be ranked high for its category. If the video is popular enough it could even make it into the top ten sites that appears for a particular search term. It does not necessarily have to have links connected to it. However, if a video or site is extremely popular many people will probably add links to it from their site or page.

How Does PageRank Work?

Simply put, PageRank works by counting links and hyperlinks that are connected to a particular site. The system uses software to perform the counting process. This software is designed to analysis websites for links that are attached to a site. Once a link is found it is simply counted and stored as information for a particular page.

Counting Links to Your Site

Page Rank Works By Counting Links

The above explanation is an over simplified way of explaining PageRank so that a person can have a general understanding about how this works. The reality is that it is more complicated than it seems. This should not come as a surprise since a lot of things turn out to be complicated than they appear.

PageRank uses robots or analysis links. These robots are called spiders or crawlers. Do not be fooled, there are not real robotic spiders and bugs crawling through the internet to find and count links on webpages. Web related robots are simply software programs that run automated tasks. These types of software of programs can be used for a number of things related to the web. When it comes to PageRank they are used for counting links.

Criteria that Bots use in the Counting Process

Crawlers and spiders (programs) do not simply count a link and move on to the next site. They have to evaluate each link as a credible connection. The reason programmers must count each bot in this way is to keep people from abusing the Pagerank system.

Theoretically, a person could simply create a lot of web pages and sites and link them to a particular target site. They could do this just to get their page ranked higher on an index. Bots evaluate the following criteria:

  1. The focus of a website or page. Sites that are linked to a page with relevent information would be considered on-focus. While links from other sites that are not relevant to the topic (of a site) would be considered off-focus.
  2. The PageRanking of the linking page. Bots will consider the position of a linking page to a particular site when it evaluates a pages position on the web.
  3. When a page is being linked to a particular site, and it has a lot of links that are connected to other sites as well, then PageRank will probably look suspiciously at this site. In other words, the more outgoing links that a site has, the less credible it will appear to the bots.
  4. The quality of the links that are being connected to a particular site will also be evaluated. Sites with bad information, low ranking or questionable material will usually be disregarded by bots.

These are some of the main criteria that bots use to count links. Again, programmers must make bots perform these tasks in this manner so they will help to reduce the chances of the PageRanking system from being manipulated or tampered with. Other search criteria that bots use includes search phrases, page titles, code compliance, the weight of the source code and ease of navigation.

Ranking Number or Position Counts

PageRank uses a ranking scale from 0 to 10 to rank pages. The lower a page appears on the scale the less relevant it will be for a particular search term. The higher a page is ranked on this scale the closer to the top of a search index it will appear.

Practical Ways to Increase PageRanking

People can increase their page ranking by following these easy guidelines.

  1. Websites that are ranked from 0 to 2 should start a link campaign to attract new links to the site. This will help to boost position. PageRanking for sites also use the term PR in front of their number.
  2. Sites that have a PR3 should focus on page optimization.
  3. Sites with a ranking of 4 or 5 have an okay rating but webmasters should work harder on optimizing them to gain a better position.
  4. Any page that is ranked at 6 or above is considered a well to do page. However, a webmaster will still need to work harder to position their page. Other webmasters will also want to link to a person’s page once they realize it has a high-ranking. This too will help to position a webpage to a higher position on the index.
  5. Create good content so that people will want to continue coming back to the site. The best sites that are ranked high up in search terms typically focus on creating exceptional content and not about page ranking. Webmasters should also focus on making titles and phrases that are relevant to their topic and that are designed to optimize rank.

SEO Optimization and PageRank

SEO or search engine optimization is a critical part of the PageRanking process. Keep in mind that bots search for specific terms when they crawl over a webpage to decide its ranking. People should only place a limited amount of search terms on each page. Webpages that are loaded with search terms will often be ranked low because bots will simply view these sites as being manipulated by webmasters. Bots search for specific search term within a site that is related to a particular subject. If a site has relevant terms listed on its content a bot will find it and use the term(s) in relation to its subject. Other online media such as videos, pictures and music are examined by bots as well.

Authority Counts when it Comes to PageRanking

Sites that are used to endorse other sites are called hubs. The more credible a hub site is the more credibility that it gives a particular site authority. Websites that are competitors will usually avoid linking their sites to other pages in their category. Bots search for this type of activity and if they find it they will usually give a site a low ranking. Pages can also receive a high-ranking if it gets cited by other high-ranking and authoritative pages. The goal for most webmasters should be to have their site linked to an authoritative page if they want to improve their ranking.

Larry Page and Sergey Brin, invented PageRank and it forms the basis for how Google works. While this is not an in-depth presentation on all the aspects of Google PageRank it does give a general understanding of this technology and how it impacts the web. Some people might argue that PageRanking is no longer relevant to web ranking because of all of the other criteria that is used to check a page’s status. While Google is currently updating its technology for PageRanking, webmasters should still continue to understand this technology and not disregard its importance. Google uses this method to ensure that pages are ranked in a logical and practical manner. After all, this technology is what helped to make Google the number one web browser on the internet.
