Google Page Rank Explained

Page Rank (PR) is an algorithm used by Google to compute the relative importance of a particular webpage on the internet and assign it a numeric value from 0 (least important) to 10 (most important). This value is calculated through an iterative analysis of the backlinks to the webpage. If webpage A links to webpage B then webpage B would receive 1 “vote” towards their page rank.Why not check here google page rank.

Fact: Page Rank is calculated on a webpage by webpage basis not on a website by website basis

The importance of the webpage casting a vote and the total number of outgoing links on the webpage casting a vote are the primary factors which determine how much “voting share ” this webpage will transfer to each of the outgoing links on them. Google calculates a webpage’s page rank by adding up all of the “voting shares ” for that webpage through an iterative calculation.

Page Rank is one of the factors Google utilizes to help determine their Search Engine Ranking Positions (SERP’s). It should be noted that this algorithm is only one part of their overall ranking scheme and not necessarily the most important one as many website’s would have you believe. The general internet user has no idea about the concept of page rank and are unable to tell what a particular page’s PR is unless they have the Google Toolbar installed (or use an online page rank checker). Since page rank is part of Google’s search ranking algorithm an understanding of the concept is still important for any webmaster concerned with getting traffic to their site.

Fact: Not all links pointing to a webpage are counted as votes for that webpage

As soon as Google introduced the concept of page rank unsavory webmasters developed ways to manipulate the rankings. These webmasters began creating web pages with the sole purpose of increasing the amount of incoming links pointing to their website.

Common Black Hat SEO Techniques:

Link Farms – pages containing long lists of unrelated links set up for the sole purpose of manipulating search engine rankings and page rank
Doorway Pages – orphaned webpages either on the same website or distributed throughout the internet stuffed with keywords containing links to the offender’s site. Used to artificially inflate the back link count for a website.
Free For All Links Pages – a type of link farm where, as the name implies, anyone is free to post their link. Once a valuable way to spread the word about your website, abuse through auto submissions has rendered these sites worthless and are now viewed as search engine SPAM.

Automated or Hosted Link Exchanges – sites that offer to provide “hundreds” of back links to your site instantly. Generally you will have to install some html code on your website to display their directory and in return anyone else who has this code installed on their website will be displaying your link. This is a case where “if it sounds too good to be true it is”. The search engine’s are wise to this technique and watch for unnatural “spikes” in the number of backlinks pointing to a website. In actuality it is possible to inflate your page rank with this technique but if the search engine’s wise up to your practices (and they always do eventually) you risk being dropped from their index or black holed in their rankings.
