Use ABM for a specific account problem
ABM is appropriate when a priority account has a specific challenge or opportunity that needs more focused attention than broad marketing can provide. Examples include lost momentum in an established account, a message that is not landing with particular buyers, or a significant opportunity requiring a proposition tailored to the customer's requirements.
Content engagement alone is not enough to justify another campaign. Establish whether the account needs better access to influential people, clearer communication of business value, or something communication cannot resolve on its own. Budget constraints, procurement requirements and practical evaluation needs remain separate considerations. A larger buying group is not automatically a problem, and a stalled opportunity does not by itself establish that an internal champion is missing.
