So it looks like the latest update from Google doesn’t stop at no referral data on organic search queries.  It appears that there is more to it then meets the eye.  I could be wrong here, but I have noticed a number of reputable sites losing their interior page ranks (PR).  At first I was worried that it was only happening to my clients, but when I noticed it was becoming more widespread I realized this may be yet another new fold in the Google Query Update.

How is this going to effect your site, we will still have to wait and see =how things infold.  But at least you can find comfort in knowing that your site isn’t the only site that has suddenly found all of its interior pages with Google Page Ranks go from 4/10 to unranked.  It appears that it is nothing you have done.  Google is yet pushing out additional changes.
