Let's suppose the Penguin problem is the content of the pages. I read many webmasters changed their text. Now my question is: Why nobody recovered after Penguin run for the second time?
Because the problem is related to the backlinks, indeed they need about one month to be updated by google, while the text is updated in a few days.
