That's not my interpretation of that comment. To wit: There are only a few things you can know about someone clicking 'buy' as the result of an ad: 1. The ad platform booked top-line revenue 2. The seller booked top-line revenue 3. The buyer exchanged money for something they thought was worth it at the time of purchase. That's it. Even #3 is conjecture, but it's likely enough that I'm willing to run with it for sake of argument. We do not, and short of asking, can not know if that purchase added value to the buyer's life.
