What GEO Wiki is
GEO Wiki is a free, open-source encyclopedia about Generation Engine Optimization, or GEO, the practice of shaping content so AI engines cite it in their answers. It appeared as AI search grew quickly and practitioners needed accurate, shared knowledge about how these engines choose what to reference. The site is bilingual, offering both English and Chinese versions, and it aggregates concepts, methods, platforms, and research in one place. Content is drawn from first-hand materials, and the Pulse section refreshes every two hours to track platforms, search engines, suppliers, and research institutions. Everything is free to read, and the project is open-source.
What you can do with it
- Look up encyclopedia entries on GEO concepts and get detailed explanations.
- Follow a learning guide that moves from basics to advanced applications.
- Read practice manuals, research papers, and industry benchmark data.
- Compare GEO with SEO, AEO, and LLMO to see where they overlap and differ.

What to watch out for
GEO Wiki is a knowledge resource, not a service that optimizes your content for you, so expect to do the work yourself. The field is young and changing fast, which means entries and benchmarks can age quickly; recheck the Pulse section before relying on older advice. Because GEO practices are still forming, guidance may not apply equally to every AI engine. Treat it as a starting reference and verify claims against primary sources. The free, open-source model is the current setup and may change, so confirm the site's status if you plan to build a workflow around it.
