This document introduces the concept of a marketing scorecard to measure marketing performance. It discusses measuring three key areas: 1) the universe of potential customers and how they differ, 2) the content and targeting of marketing messages, and 3) the results and effectiveness of marketing in generating revenue. The scorecard would translate these measurements to an online context. It provides examples of specific metrics that could be measured, and concludes by proposing next steps to apply the scorecard concept to a organization through a pilot project.
