Last month I moved about 5 of my categories over to subdomains and 2 of them recovered to pre panda levels 3 days after implementing the changes. However as of early this morning all the of changes are back to post panda levels. And these were my best categories. Last week was my best week since Feb and it seemed like I was back on track after 8 months because I noticed that my google profile pic was showing for about 15 of my pages in the results which had me thinking that I was doing it right because my profile was being associated with the pages. However this minor tweak sent me to the back of the room again.
