Marketing teams that combine performance metrics with account-based views can demonstrate additional value and make better resource decisions. The metrics used to evaluate account-based marketing (ABM) performance include measures of impact, output, activity, and readiness viewed at the account level. ABM performance has six reporting dimensions that help organizations align and organize account-level metrics used to evaluate ABM investments. In this report, we define ABM metrics and performance reporting and outline six dimensions of ABM performance reporting to help marketing teams demonstrate ABM efficacy in an aligned manner.
