/\ Not sure about penalty, I think they are sending traffic to sites in the hope that people do not check where this traffic is coming from! I've spoken to others who are seeing the same as us. Surely Google don't think we are this stupid?! Or are we all getting too paranoid & this is an algo fault (much like the GMT language bug!)which they are trying to control? Just checked the SERP's and the data set I see is Product Search one box on top, then Wikipedia then organic. Wonder when this will flip today?!
