About GEO Wiki

GEO Wiki is an open-knowledge encyclopedia for Generative Engine Optimization — the discipline of making content discoverable, citable, and trusted by AI search engines (Perplexity, ChatGPT, Google AI Overviews, Gemini, and the rest of the field).

Every entry is bilingual (English and 简体中文), source-first, and published under a permissive open license so it can be cited, quoted, and remixed by both humans and the models that will read this page next.

What we cover

• Wiki — definitional entries on GEO concepts, engine crawlers, comparisons (SEO / AEO / LLMO / GEO), and the companies and standards behind AI search.
• Playbooks — repeatable, step-by-step methods for audits, citation tracking, brand-mention monitoring, and the other day-to-day operations of a GEO program.
• Research — original papers and a curated reference library on AI search behavior, evaluation, and governance.
• Platforms — per-engine deep dives on the major Western and Chinese AI search engines, with crawler user-agents, ranking signals, and access policies.

Editorial principles

1. Source-first

Every non-obvious claim cites a primary source — a paper, vendor documentation, or first-party measurement. The sources: field is part of the content schema, not an afterthought; an entry without sources cannot ship.

2. Term honesty

When we coin a term that isn't yet industry-standard, the entry says so plainly — a note on the term at the top, and a Industry-standard term? No row in the quick-facts table. Coinages are anchored to the established term they build on, never passed off as common usage.

3. Bilingual parity, not translation

Chinese entries are idiomatic rewrites at the same depth as the English, with localized punctuation, register, and examples — not literal translations. A four-round blind-polish review enforces native rhythm before any zh entry ships.

4. No SEO theater

Entries are as long as the topic requires, no longer. We don't pad with hedged language, write to a word-count target, or stuff site-architecture meta-talk into the body. If a section doesn't pay for its space, it gets cut.

5. Open methodology

Where we publish a benchmark, score, or audit framework, the methodology lives in the same entry. Readers — and the models reading after them — can reproduce, critique, or extend any measurement we publish.

Who runs this

GEO Wiki was created and is maintained by Ray Yang. Entries are reviewed against the editorial principles above before shipping; sourcing, methodology, and bilingual parity are gated by tooling at build time.
