The B2B AEO Strategy. How Enterprise Buyers Use AI to Discover Vendors.

The B2B buying process has been restructured

Enterprise buyers do not cold-call shortlists anymore. They ask AI. Sixty percent of B2B buyers now use AI during the vendor discovery phase — up from approximately 30% eighteen months ago. The businesses that appear in the answer own the deal before the first sales call.

Where B2B buyers are in the AI funnel

Discovery happens at three stages. Problem awareness: the buyer asks what is causing their problem. Category evaluation: they map the vendor landscape. Vendor validation: they verify specific brands they are considering. Zero AI presence at any of these stages means zero influence on that buyer's decision.

The content types that win in B2B AI search

Definitional content, comparison content, and case-specific guides earn the most B2B AI citations. Tracking your Share of Answers across these queries — see the AEO tools guide — tells you exactly how visible you are at each stage.

The entity problem for B2B brands

Most B2B brands have strong human reputation and near-zero AI entity recognition. Implementing Organisation schema is the single fastest fix. A company that has operated for twenty years but has no schema markup is invisible to AI retrieval systems.
