  Tony McCreath: This is the toolbar pagerank which is an infrequently updated rough score based on the true PageRank result used in the algorythms.
  
  A new website page has no pagerank. Once it's been evaluated it gets a score from 0 to 10 which is a exponential scale where 10 is the highest.
  
  Page rank is based on links to a page and the PR they have. A PR of zero means you don't have many.

  PageRank is only one of the many factors Google uses to determine what makes it into a particular search results. And the Toolbar PageRank we see is a very rough and out of date estimate to that.
  
  Don't chase Toolbar ;PageRank. Just use it as an excuse for a celebration if it goes up. Chase the true goals for your website: traffic, leads, sales, subscriptions, MONEY.
