GEO Wiki

GEO Wiki is an open, bilingual encyclopedia for the emerging field of Generative Engine Optimization (GEO). It exists to document how content gets retrieved, used, and credited inside AI-generated answers — a shift the project contrasts with traditional SEO, which mainly targets ranking in search results. The site organizes its material into a wiki of definitions, profiles of major AI engines, practical playbooks, and a curated research index.

A defining characteristic is sourcing discipline. Key claims link back to their origins, and the project describes itself as prioritizing primary sources. Alongside the encyclopedia, GEO Wiki maintains a Pulse feed that aggregates official updates on AI search and GEO every couple of hours, drawing from platforms, search engines, vendors, regulators, and research institutions, with direct links to the originals.

The site is also hands-on rather than purely theoretical. It ships free tools that turn the guidance into checks: a citability checker, a schema markup checker, an AI crawler access checker, and an llms.txt generator. Coverage extends across engines such as Perplexity, ChatGPT Search, Google AI Overviews, and Gemini, and the encyclopedia is bilingual in English and Chinese. For anyone learning how AI search visibility actually works, it reads as a structured starting point rather than a marketing page.
