Creating an Amazon ad campaign with just 1 keyword in it? Utter madness? Perhaps not. The theory boils down to being granular with your campaign structure, and also being well organised. My good friend Florian believes that chucking your top-performing/high-focus keywords into their own campaign allows you to: Set placement bid adjustments for each individual keyword; Have full control of your budgets on a granular level; Always have the performance data in mind when opening the advertising console (campaign data = keyword data)
