Well, I just hit rock bottom with Google Merchant Center, as in 0 clicks. I made all of the changes required to the data feeds--adding google_product_category, availability, shipping_weight, etc--but my clicks fell to zero starting on October 11.
The performance chart is showing that most of my items were disapproved starting on the 11th, although the list of products in my account doesn't show that. I do know that I haven't received any sales from Google Products/Merchant/whatever since last week.
I used the contact form to ask Google for help, but I have no idea if they'll reply.
Between Panda, the loss of Google Product traffic, and some changes by manufacturers whose products I sell, I'm hurting bad. No amount of paid advertising on Adwords or on other websites is making a difference.
