Many of us saw considerable changes straight after Panda 4 only for many promoted sites to sink slowly back into nowhereland and major brand sites to float back to the top. Were Google just playing with us? Did they turn the dial back? Was it user metrics that made the difference? Or were there other factors in play?
I think it is very important to get a good idea of just what happened and why because it could be fundamental to the way we should design and promote our sites in future.
So; did your sites rise and then fall? Did they rise, and keep rising? Did they never rise at all at first but do so afterwards? And most important of all, do you have any idea why?
