How this was measured: OrgScanner asked Anthropic Claude 3.5 Haiku, Google Gemini 3.5 Flash, OpenAI GPT-4o mini the 12 buyer-style questions a real customer would ask for “real estate agent in Boston”, and recorded which businesses each model named. A point-in-time check, not affiliated with Century 21. Generated 2026-06-17.

• We asked Anthropic Claude 3.5 Haiku, Google Gemini 3.5 Flash, OpenAI GPT-4o mini 12 buyer-style questions for “real estate agent in Boston” — Century 21 was never named, effectively invisible to AI search.
• AI surfaced 5 other real estate agent businesses by name instead — Century 21 was left out.
• No llms.txt found — AI has no machine-readable profile of Century 21 to quote.
• Likely missing LocalBusiness JSON-LD schema — without it AI can’t reliably extract your services, hours, and service area.
• No GEO content answering the exact buyer questions (“best real estate agent in Boston”) that AI pulls from — the Fix Kit ships 5 ready templates.

Publish a machine-readable llms.txt + LocalBusiness JSON-LD for Century 21 so AI can extract and cite it — the single reason 5 other real estate agent businesses get surfaced for this search and Century 21 does not.
