The success of any website depends on the rank that is assigned to it by standard search engines–the greater the rank the higher is the possibility of getting noticed on the Internet. Websurfers are usually attracted to the web pages according to their ranking in the search engine listings. The ones in the top ten positions are visited the most. For improving the PageRank of a website it is vital to know the process in which the ranking is done.
The PageRank (PR) given to a webpage indicates its importance. The webpage that ranks first is, obviously, a lot more vital than the webpage that ranks eighth or ninth in the search engine listings. Google is considered to be the most vital search engine by the web browsers. For assigning PRs Google first looks for pages that are linked up with other sites the most. When one webpage links up with a further webpage, Google interprets that the first webpage is casting a vote for the second webpage. The importance of a webpage is single-minded by the number of votes it gets–the greater the number of votes, the more vital it is perceived to be. A further factor that determines the importance that a webpage gains depends on the significance of the voter itself. If a webpage gets its votes from web pages that are very vital, it is considered to have a greater importance than the ones that are voted by a large number of web pages that are not all that vital.
The PR feature is one of the vital factors that determines the rank that Google assigns to the webpages in its search engine results, though it is not the only criterion for deciding its search engine rankings. The search engine rankings are influenced by factors other than the PR feature too.
While calculating the PR Google does not take all the linkings into account. If a webpage is getting links from known link farms, the link is not considered for deciding upon the PR. Link farm can be certain as a group of websites that hyperlink to every other site existing in the group. In fact, a webpage can get into distress with Google for between up with certain links. Google does not penalize webpages for the links that involuntarily link up with them, but they certainly penalize a webpage for forming some unfavorable links, because forming links is in the hands of the webmasters, though getting involuntarily linked up is not controlled by them. Hence a webpage needs to be very careful about the association that it makes. Usually sites that have a PR zero are the ones that are under a penalty and they should not be linked to.
For calculating the PR, the number of its inbound links is first considered. Google has a generalized formula which it uses to calculate the PR. When a webpage links to a further webpage, it gives it a certain PR value by voting for it. This PR value should be slightly lesser than its own PR value. This value is equally distributed among all the web pages that it links to. For example, it is permanently better to get a link from a page that has a PR value of 5 and has six other links than from one which has a PR value of 12 and links up with 20 other web pages. This signifies that getting links from web pages that have numerous other links is not really helpful. It is better to link with web pages that have a high PR and link up with a lesser number of other websites.
It is also seen that the difference between the PR principles of web pages is not copy, i.e., the difference between PR1 and PR2 and the difference between PR2 and PR3 is not same. It is believed that the difference is set on a logarithmic scale and it takes a greater amount of PR value to go from the one rank to the next higher ranks. In such a case it is seen that between with a webpage that has more PR value is more profitable than between with a webpage with lesser PR value, which is a divergent result to what has been deduced from the previous close. But, in any case, it is seen that between with other web pages increases the PR value and it is permanently better to avoid between with link farms.
It should also be borne in mind that by voting for a further webpage, the PR of a webpage does not decrease. But it is seen that the PR is lost in an indirect way by between to other sites.
