Madison Avenue loves these "inefficient" ads because they get to play the part of "cop" in the classic prisoner's dilemma. Let's say you release "Brand New Purple Foobars!" and hire my ad firm to advertise them. Sales are up, so what's your conclusion? Well, maybe my ads really helped push your product. OR maybe your product was just so awesome on its own that it didn't need any advertising. The question is, if you don't know for certain which it was, do you take the risk of not hiring my ad firm next time? What if you don't, but your competitor that just came out with "Brand New Yellow Doohickeys!" does? The problem with Google's ads is that it removes the mystery. If I know how many people saw the ad, and how many people followed through and clicked the link, then I can evaluate how effective my ad campaign is directly. It's like giving the prisoners cell phones so they can text each other… "Hey, they said you confessed…that true?" "Nah man, you?" "Nope!" "Cool…so drinks later?"
