Like so many here, I took a 40%+ hit in traffic from Panda. Sales fell off as well.
On the first of this month, one of the manufacturers whose products I sell started a 90 day rebate offer that's worth anywhere from 16% to 27% off.
Sales have been great, not only for this product line, but for other manufacturers.
Here's what's weird. I'm running Adwords for the rebate, but get a conversion maybe every other day. So, the sales aren't coming from Adwords. When I look at my log files each day, the conversions are coming mostly from Google. But my site doesn't show up in the top 30, 40 or 50 results for any of the phrases.
The only place on Google that these conversions could be coming from would be Google Products, where I still rank very well.
I never saw much activity from Google Products in the past. The conversions that weren't coming from Google Adwords were coming from Google organic, where my pages were (stress "were") first page.
Why would I suddenly see so many referrals from Products? My sales so far this month are 280% of what they were for the same period in April of last year.
Could shoppers be using Google Products more since Panda than they did before?
