ABM metrics measure account-based programmes at the account level rather than the lead level: coverage of the target list, engagement depth across the buying committee, pipeline created and influenced, and win rate against targeted accounts. Lead volume is the metric ABM is specifically designed not to optimise.
Four numbers carry most of the weight. Coverage, meaning the share of the target list with any engagement. Depth, meaning how many people per account, because one contact is not an account. Pipeline created from targeted accounts. And win rate on targeted accounts against everything else, which is the only number that proves the approach rather than the activity.
Because ABM deliberately influences accounts over long periods through channels that do not produce clicks. Last-touch attribution will credit the demo request form and ignore the eleven months before it. Account-level influence is the honest measure, and it is softer than finance usually wants.
Reporting engagement as if it were progress. An account that has engaged is not an account that is buying, and a dashboard full of rising engagement with flat pipeline is a programme that is busy rather than working. See full-funnel ABM for why this gap usually exists.
