I think there's so much snake oil in the ad business because it is indeed hard to measure the effectiveness of ads, in particular when shown in places where you cannot track the user behavior and correlate the ad with subsequent user behavior. In the end, platforms like Netflix and Hulu don't need to prove that a higher volume works, but perhaps their customers think that it works, and that is enough.

Or the alternative, you can track it therefore you assign a disproportionate amount of value to it versus the things that are harder to track.
