I am aware that if a site has been Panda penalized (I am not talking about manual penalty), it does not help to try to change of URL only.
However, when corrections have been implemented properly (thin content has been beefed-up and near duplicates have been canonicalized in my case), does it help to change of subdomain URL?
Does it accelerate the recovery process? Or should I be patient and wait until Google finds about my changes? Is there a delay before Google will reconsider one's Panda correction? If yes, what would that delay be?
