I have 2 sites that have been around for some time. I have no idea what the PR's used to be on them since I just found out about the PR rating. Actually I did see a category listing on Google that I was in and it had a green bar next to it that looked like I had a PR1 at some time. We are ranked 2.6Mil or so on Alexa. The site went through a major change 2 months ago. We changed it from a flat sight to a dynamic site. A week ago the caches had the old version but as a few days ago had the new site on the cache. Now we have about 7 sites most of them have their own IP. Most of the sites link to each other. I just added a Site Map today since we use graphical DHTML menus. I know this is a lot but I wanted to give all the information that might help in answering my question. We get a lot of hits because we do a lot of Pay Per Click advertising on overture and looksmart. Almost all our clicks come from that or from direct URL type ins. We do a lot of print and TV advertising. I get about 20,000 page views a day from all my sites. 3 of the sites get about 250 visitors a day. I filter out as many bogus hits from the stats as I can. Why do I have a PR0 on all my sites even the old ones?
