The goal of the research was to identify and better understand the incidence of sub-optimal digital campaign delivery as it pertains to viewability, audience delivery, geographic targeting, and brand safety. Through an evaluation of the study findings, several significant empirical generalizations emerged, and this article highlights these generalizations and discusses their implications for the digital advertising ecosystem.
