Backlinks are also used to calculate and determine a page rank in several search engines and a part of the SEO service. These backlinks need to be relevant to the pages linked to them, and the pages should have high ranked too for the page to move higher in the ranks ladder. The process of determining page ranks through backlinks is known as link analysis.
Searches based on a keyword and links to a website can both be used to determine a page rank in most search engines. With this in mind, many SEO Specialists would use keywords and PR links to optimize their websites, which would help promote the page’s rank in the search engines. This method was and is still in use today, as it creates a higher visibility of the page to engine crawlers, thus higher page ranks.
All these started to change when Google was launched, and started to take effect towards the end of 2006. Although there were other search engines in use, more than 50% of all internet users preferred using Google over yahoo, which came as a second option.
Google’s fame of use came into full force after it implemented PageRank as a patent to govern how SEO was to be undertaken by website owners in the quest to gain higher ranks within Google. Stanford University took the role to make sure the PageRank program was streamlined and effective across the internet. This program was Larry Page’s and Sergey Brin’s brainwork in the university and although it was purposely a research program, it did earn Google favor among internet users.
Google uses an algorithm method to determine and work on pages, where analysis is conducted on each hyperlink; it’s relevant to a search and subject matter and density to come with a final result. Through E.PR, Google can measure relevance and suitability of a page before determining its rank.
The main mode of mechanism in this algorithm is mostly based on hyperlinks and texts linking the website with other relevant sources in the internet. These act as a voting mechanism, with each link to the website giving it a vote to move up the PageRank ladder. This means one has to work on relevant links to and from the website to get a higher visibility and PageRank in Google searches which is the aim of the SEO services.
This method of determining a page rank in Google is not foolproof, as webmasters and online marketers can use it to advertise their pages for SEO and SEM. This is a spamdexing feature that has made it possible for these SEO specialists to better optimize their websites with relevant links and content. Google measures a PageRank with 8 digits, which are placed directly beside individual websites.
As time progresses, Google has been able to come up with a program that supports LSI keywords to determine PageRank’s. LSI keywords can be in the form of synonyms, or related words to support a marketing campaign.
