I have seen a loss in traffic right around the beginning of May (which doesnt correspond to any of the google shifts). I have no messages in WMTs and have not seen any real loss in rankings from the hundreds of keywords I check.
It was right after a go live that we did. On this go live we added social buttons (FB, Twitter, Google +), effectively adding them to over 10,000 pages. I have seen a drop in traffic since then but in my segmented data cant pick an engine, or part of my site that has been effected alone it seems like it is more all up overall.
So I am wondering if this could have been effected by the social button roll out and or effect on load time or such. What do you guys think is this possible or should I look at the other changes?
