Then there is 'selection' which is picking the 'best' product in a competitive landscape. Here I'm not convinced even Tech has this captured. If I am shopping for cars, for example, I might get a Tesla Ad (they do have a few AdWords) but the technology showing me that AD isn't optimizing for me, it's optimizing for a click-through or maybe a conversion which are different things. Maybe you look at me, my income, my driving needs and say hey - look, maybe you want to go with like a Kia Crossover over a Model S. A Model S would be fairly financially irresponsible given your income. The money saved with a crossover would equal $XX,XXX by the time little Bobby is ready for college. And what about those camping trips? You occasionally drive further than the expected range anyway.
Right now if I want to compute the TOC of a Tesla vs a Kia given what I usually drive in a year minus the tax incentives or whatever I'd have to bust out excel and spend a few hours. This isn't sexy. This isn't what advertising used to be, but if they want to do the math for me I'd pay attention to that way more than that I do AdWords.
