I've noticed something strange with how Google ranks / indexes dynamic content. One the same site I have a mix of plain html pages and dynamic ones. An example of the dynamic url is something like this: www.mysite.com/scripts/ABCEContent.dll/ShowPage?PageName=wheretoeat, this page has a PR 0 while this html page: www.mysite.com/wheretostay.htm has a PR 4. Both pages are indexed, any ideas why there is such a big difference?
