More and more sourcing engineers now throw their selection questions at ChatGPT, Gemini or Perplexity before opening a search engine. For suppliers this means a new discipline: GEO — making your products visible, understandable and accurately citable by AI engines.
AI citation works differently from search: it favors structured data (Schema), quotable FAQ phrasing and answer-first paragraph structure. In practice, sites with complete Product Schema + FAQPage are cited several times more often.
The checklist: ① generate all JSON-LD from templates; ② write FAQs conclusion-first with data support; ③ publish llms.txt / agents.md machine-readable protocols; ④ monitor brand mentions across ChatGPT/Gemini/Perplexity regularly.
FJFilter is built this way: 240+ products with complete Schema, 58 quotable FAQs, llms.txt and agents.md live. When a buyer asks AI 'which planetary gearbox supplier has the lowest MOQ', we want our name in the answer.
