I just discovered that my site has lost almost all its rankings. I was ranking number one on Google for a number of keywords but I just tried all of them to my utter dismay. All the rankings are gone!!! I thought my site was not affected by the Penguin update because while others were complaining, my site was doing well. But now it seems I have received the hammer as well. What I want to find out now is this...Am I the only one affected by this? Is it the usual fluctuations we normally experience after which sites ranking returns to normal? What can I do now?
