This document discusses best practices for programmatic advertising. It recommends (1) optimizing ads based on advertiser goals like sales or leads rather than publisher metrics, (2) starting with goals like awareness or purchase intent and mapping the customer journey, and (3) developing your own attribution model to understand customer touchpoints rather than relying on default models. It also warns against "reporting magic tricks" and advocates for transparent reporting and always-running "time-based" campaigns to continuously improve performance over time.
