Just had to come back here to see what's going on with Google. Since May 18th we slowly recovered to "normal" traffic and sales levels. Over the past week or two, sales and traffic have again gone flat.
OHNO - We are in the same boat again. Hope this straightens itself out soon.
BTW, we are still listed at the top, but the little traffic we are getting appears to be foreign & poor converting. I had three sales between 8:37am and 8:58, then one at 9.50, then nothing all day. This is far from normal.
