To note that this article is some subtle informercial to subscribe to some tool to optimise and automate a sellers ads bidding.

Edit: What a paradox, criticising Amazon for its vampire attitude (takes a cut on the sold price, on shipping costs, on inventory, on returns, on ads). The points are valid, but the author is trying to sell a tool starting at $29 per month + 4.5% of ads cost. This tool could easily be integrated in the Amazon ads system, it wouldn't surprise me.
