ranking above major sites some product search terms however my PR is still a whopping 0 is it cause its changed but hasnt fully updated in the toolbar/directory?
PR seems to update at random and wacky the past few months/years. As long as your site is ranking for terms, forget the green exists for a while
PR doesn't make you rank... well not directly. Besides, it's constantly updated - but the toolbar you use isn't. Therefore, your not actually looking at your current PR.
Forget about the PR or you will be wasting your time like half the people at the google forum clicking on each google has updated PR thread Got the serps. good job.
