Would respectfully disagree. Matching a consumers query to an ad, and optimizing that outcome at a given return on investment threshold is a task best left to a computer to optimize. It is a perfect use case for reinforcement learning, and a computer can work 24 hours a day and you need to sleep. In my experience, 100/100 times the machine beats the confident manual optimizer. We (humans) don't have a great track record in beating computers at these kinds of problems, certainly not a game as simple as optimizing for a high score (driving results from an ad).
