Poorly-conceived article. tldr: Search advertising doesn't seem to work because you don't know whether people would have bought your products anyway, and the advertisement for the search term "Nike" appears directly above the organic result of nike.com (thus it's apparently a waste). According to the article FB advertising doesn't work because you'd probably have bought the products that are shown in the retargeted ads you constantly see anyway. The problem with this analysis is that it oversimplifies online advertising to the point of making the argument completely worthless. He's arguing all advertising is a waste of money because, apparently, some advertising is a waste of money. It makes no mention of the quality of the ads that are written or their placement or their budget. It basically says "my gut tells me people probably behave in this manner because I think I behave in this manner and some paper written by eBay seems to confirm my instincts."
