What is PageRank?

PageRank is "Google's measure of the importance" of a certain webpage. PageRank helps to determine how your website or a particular webpage will rank in a Google search.

PageRank is determined using a serious of algorithms which calculate the quality, and the relative PageRank of the sites and pages linking to other pages on the internet.

All webpages indexed by google have a PageRank of between 0 (bottom) & 10 (top). Webmasters often try to increase their PageRank so they can tap into more traffic from Google searches.

It is not uncommon for different pages on a website to have a different PageRank, due to the fact that they may be second or third tier pages in your sites hierarchy - and certain pages may be linked to more from external sites.
