In order to provide a quality user experience, advertising platforms typically require that all ads, assets and destinations meet high professional and editorial standards. Advertising platforms' editorial policies may provide guidelines to help you create ads that are clear, professional in appearance and that lead users to content that is relevant, useful and easy to interact with. Ads that violate these policies may be disapproved by the advertising platform.
