i've published my e-commerse site 3 months ago. it was rising day by day but at 16 february something gone wrong and it started to fall dramatically. 1.5 months ago hits were around 150 but now 20 ~ 30 i think that's the benefits of updates for me..
I think we all have to avoid guess and rumors, as there is not any official announcement from Google..So, we all can just wait and watch..
My traffic went up. Seems white hat is still the way to go. All my competitors got hit hard, while my site earned a lot of new long tail keywords it is ranking for. I love you google<3
