Has anyone seen this behavior?

We were well on our way to some decent (well improved) Google ranking. When along came the 2007 upgrade. Now when you look for our keywords, we show NOWHERE on any Google page. Even if you put the specific text that is on our web page in quotes and only 77 match that in the whole world, we no longer show up. It's as if we have disappeared entirely from Google world.


Here's the reponse that I got from support today:[INDENT]I understand that you seem to have a Google dropped ranking that seemed to have occured from the system upgrade, however, we were able to find that Google's PageRank is currently being exported (starting late July, 2007). During this time you may see fluctuations between the old and the new PageRank score on your Google Toolbar, and occasionally PageRank may not appear at all. These shifts will eventually settle down as the new data replaces the old on all datacenters during the coming weeks.
