And it seems like unless you go to a lot of trouble, you're essentially relying on the ad network's own metrics for efficacy... Which when you consider the sheer quantity of money at stake, seems like it will end in a massive fraud at least once. I could be wrong about the perverse incentive though, it seems almost too obvious so I would assume that people who know the ad industry better than me would have a response to it.

There's a whole ecosystem of "buyside verification vendors" that advertisers contract with to validate that they're getting what they paid for. Buyers don't just take the seller's word for it, or at least enough of them don't that shady sellers are kept in check.
