I used help support to ask why my rpm to a dramatic hit the last 2 months. Answer was canned predictable and told me absolutely nothing. Anyway was worth a try. Interestingly the drop in RPM coincided with a message in adsense telling me to move from 120x600 to 160x600 which i didn't do as I would have to change a custom theme. Anyway as the rpm steadily declined I spent 2 days modifying my theme only to find that 16x600 made absolutely no difference. Anyone else see messages like these in there adsense account?
