There must be something wrong.. give here complete details and url of your site only then anyone can help you!!
Just get some good backlinks on High PR site ... then positively u will get better PR ..all the best thanks .....
How long your site not being update? Major PR update, i mean PR tool only update the PR few times a year
If the update happens and other peoples website got PR while you are none. The few possible reasons are 1. Your website has not enough high PR link pointing towards it. 2. Your inbound link page has a lot of outbound links that caused dilute each PR passed. 3. You have too many outbound link on your homepage. Both internal and external links.
Depends on how old your site is, and the quality of the backlinks you are gaining. If they are all from PR0 sites then there is little benefit.
Try to get some quality do follow backlinks. But why you giving importance to PR, your traffic or keyword rankings are not going to improve from PR.
