Page Rank: it's an algorithm created by Google to calculate the IMPORTANCE of a web site or page.
The Page Rank is calculated by counting both the number of external links to a given site and the quality of the links, (quality means the pertinence to the argument treated); it also takes into account if the site containing a link to your site is also linked in your site.
