Advertising doesn't work that well if you look at the raw numbers. Assume you have a great campaign and awesome conversion funnel, so that you get 1% clicks and 1% conversion. The math is 100 x 100, or one sale for every 10,000 eyes who sees your ad. In a vacuum, those numbers are awful. If your entire marketing strategy is buying ads to convert to sales, then of course, advertising doesn't work, and really, you probably shouldn't be advertising in the first place.
