I don't think they have anything against it. So, what kind of site that you use for both mobile and normal web ads ? All i know that most of publisher would rather go with other mobile ad network like MobGold, Smaato, etc, rather than showing both web and wap ads.
yes they are! I use admob to do cpa offers and i am able to profit $2.00+ per cpa i do i preferre admob for mobile cpa but adsense for websites/ google pc traffic
I actually was going to make my android site in my sig into a normal webpage. I still use admob just Optimized my site show it shows up different on a cell phone.
