Let me hazard a guess... entertainment and game sites with lot of graphics will benefit from Google's new image layout, while text-based websites will suffer. That could explain why some sites are doing better, while others like mine are doing so much worse. But it could have been the best of both worlds if we can get the "text-only ads" to work. Apparently, the option is not working at the moment.
