This document discusses how to prove the success of an Account-Based Marketing (ABM) program in 6 months or less. It recommends defining success metrics upfront and focusing on 3 main metrics: relationships within accounts, reputation, and revenues/pipeline. It then provides examples for different ABM strategies, showing how the metrics could improve over 6 months to demonstrate success. For a 1:1 ABM approach, the goal may be strategic conversations and meetings. For a 1:few approach, the goal could be opportunities created. And for a 1:many approach, the goal may be overall revenue targets. In all cases, the document stresses establishing a baseline to measure improvements over the 6 month period.
