I suppose really what you are saying is it is different to selling a product you cannot calculate a direct return on investment. Which is true to some extent i think you can track visitors coming from adwords or organically with analytics. However this still does not help you work out anything meaningful really.
I guess something that it could be used for is to give you something to play with and learn how to use adwords, and test different ads and ad styles to generate visitors. May be something that i might look to invest a little money in and see what sort of response that i can get.
