As AI answer engines become a primary buyer research tool, “share of model” will emerge alongside “share of voice” as a critical AR metric. It refers to how prominently and favorably a vendor is represented inside AI-generated answers when buyers ask mission-critical questions. Vendors whose content is not structured or distributed in ways that LLMs can easily interpret, trust, and cite will find their influence diminished in AI-first journeys – even if they retain strong brand recognition in traditional channels. Achieving share of model requires AEO-friendly content: modular, schema-rich, factually dense, and consistently narrative across all surfaces (analyst portals, co-pilots, and answer engines).
