Am I the only one that finds it insane this wasn't a feature earlier? They seemed to just rest on the idea that their optimization algorithms did everything right, even though they acted incredibly prematurely. They also seem slow in rolling it out since I've been hoping to see some of the known features actually show up in my account, requesting them, etc. and still nothing.
Yes and no. It's not insane from Facebook's perspective. If you're wasting money on Facebook ads, why would they want to give you a tool that helps you figure it out?
What mystifies me is that people haven't demanded more of this. People spend literally billions on online ads, with very little ability to validate whether it accomplishes anything. The fact that they haven't been screaming for rigorous experimental trials of ads for years blows me away.
