Hey no i dont think you can, im pretty sure google doesnt like that. From my experience you cant put it on the same page you are driving adwords too. However, im pretty sure u can put adsense on the inner pages, aslong as PPC traffic is driven DIRECTLY to that same page. hope that helps

definetely no arbitrage on adsense,
if you want to maintain your adsense account

No you defiantly can't. It would be considered arbitrage like Frank said.
