That's a nice theory but doesn't mirror my experience. Online ads will be for overpriced junk, when it's not literal scams. The reason is it's all highest bidder, no quality control. If there was an ad network with a brand, with a reputation for only running ads for high quality products at competitive prices, then maybe I'd pay attention. EDIT: Writing this comment made me consciously pay attention to ads to verify my thesis, but honestly the quality was better than I expected.
