Today I woke up just to see that my site was deindexed for both main keywords in google (In yahoo i am still 1st). But when I search for site:mysite.com I find my site but the meta title and description was changed a month ago, and meta title+description was updated. But then I also checked my blogspot article which was ranking 1st for synonym keyword. I found it on page two and when it indexed it was even on page two. Anyone have any idea what happened? I really doubt that one of google datacenters have not been updatet for a month.
