What it means
PPC (pay-per-click) is the billing model behind Amazon Advertising: you don't pay for your ad being displayed, only when a customer actually clicks. Sponsored Products, Sponsored Brands, and Sponsored Display predominantly work this way; the price per click is called CPC and is determined in a second-price auction. Efficient PPC management covers keyword research, bid optimization, and negative-keyword maintenance — success is measured primarily via ACoS, ROAS, and TACoS.
