It is looking like we've been hit by Penguin 2.1 (5th Update). There was a significant drop in organic traffic on 6th October 2013. There was another drop around 17th March 2013, which looks to be related to Panda update 25. However, weirdly enough we recovered quite considerably from 7th July until Penguin 2.1. Is that something that others have experienced as well?
In view of this, does anyone have any specific advice?
