@kredJun 12.2014 — #The time firstly depends on the type of penalty. If it's manual penalty then you can recover a couple of days after successful lifting the penaltyy by Google employee. In algorithmic penalties (Penguin, Panda) the time varies and depends on the time, when you eliminate the causes of penalty.
