Track your metrics!

You could say, hey, are there any placements that are cheaper than others? And then you can also do some small micro tests by testing very different things across the board, whether it's a headline, kind of similar kind of things here. And you basically just rinse and repeat. Now sometimes there's not enough information to for sure tell you that, let's say the creative is the biggest problem. If your link click is high, that's when you keep going down this list. And I keep basically drilling in on these creatives or on these different metrics to see what's wrong and what isn't.
