Getting high Page Rank for your website is one of the most difficult tasks any company or webmaster will face.
It could take a lifetime to achieve a maximum page rank of 5.
Page Rank was invented and patented by Google and is based on a calculation from 0-10. In simple and basic understanding terms, Page Rank is a unique way to gather relevancy regarding your website and how authority your website is including what type of backlinks your site has and the quality and relevancy of those backlinks your site has.
If your site has edu links pointing to it or gov links pointing to it for example it must be very authoritative, or if your website has many natural links and discussions are made from natural sources mentioning how great your website is online and are pointing to your site, this tells google that your site is popular and gives you a ranking accordingly.
Page rank is updated quarterly but has no specific date on update and as a result webmasters around the world are always patiently curious or inpatient to find out when their site will be updated.
Large website companies that are on a page rank of 6 or higher are usually International news websites which naturally grow very popular and as a result reach high page rank, and go as far as company websites such as pepsi.com, adobe.com and even google themselves.
I am very proud to have recorded my own success regarding page rank for one of my website SEO2Webdesign.com , which has finally reached a whopping Page Rank 6 from the very most recent update on 27th September 2008
