i had a site that was updated to PR6 last week and now after over 1 week with PR6 droped to PR5 maybe google started to update the PR continually..
I think google have cocked up something somewhere, my internal pages on one of my sites, went from PR4 to 0. *sigh*
same with me 2 pr 4 sites dropped to pr 2 and a pr 5 dropped to 0, is there no method to this madness? Just keep building only advice I can offer.
