Digital marketing is a solved problem. You pay a commission on verified real sales to affiliates, and they can do what the hell they please to make those sales. If somebody like Google or Meta cannot promise X amount of sales for Y amount of ad money spent, then you are a fool to give them any money. They have all the algorithms and profiles on everybody, so it's their job to match your product to customers. Why should you have to tweak who will be targeted?

Well, the answer is that many people owe their paycheck to not letting their employers or shareholders know that digital marketing is a solved problem.
