I came to know that dynamic URLs( URLs with Spl. Characters) doesnot attain PR and doesnot even get cached. But some URLs are having PR. How does this happen?
Dynamic pages do have PR, but the toolbar has issues displaying it as it does not parse the ?'s and other variables.. One bug seen in older versions of the Firefox toolbar, showed the same PR for a page like index.asp and index.asp?productid=1234 The PageRank toolbar is for display purposes only, so what we see in the toolbar is not the real PR, but the PR from the last time the toolbar system was updated. I believe that only a PR 0 from a penalty is live, but not PR 0 from a new site or new page. PR 0's should only be judged from the home page, or if the site is a directory as those sites are now handled differently. So we have to use some discretion in considering whether to ignore the toolbar or not. If you have rankings, and good rankings, then the PR does not mean anything.
