Hit with Penguin?
Penguin is a part of Google's search algorithm that looks after websites that are spamming Google's search results but ranking well. The update goes after websites that may have bought paid links.
If your website is hit by Penguin, you will see a drop in the traffic by today or tomorrow. To recover from the update, you will have to disavow bad links or remove them manually. Since, Penguin is an automated process, filing a reconsideration request will not help. Your website will recover when Google will see that every bad link has been removed.Penguin 2.1 Spam-Filtering Algorithm is Now Live!,
