Glossary
詞彙表
Every GEO & AEO term, in plain English.
GEO
Generative Engine Optimization — the practice of earning citations and recommendations inside AI-generated answers from engines like ChatGPT, Gemini and Perplexity.
AEO
Answer Engine Optimization — optimizing to be the direct answer across featured snippets, People Also Ask, AI Overviews and structured extracts.
SEO
Search Engine Optimization — the technical and content foundation that makes a site crawlable, structured and rankable in traditional search results.
LLM
Large Language Model — the AI system behind generative engines; it predicts and synthesizes answers from its training data and live retrieval.
Citation
A named reference to your brand or content inside an AI answer — the GEO equivalent of a ranking, tracked per engine and per prompt.
AI Overview
Google's generative answer at the top of search results, summarizing sources and citing them inline.
Featured Snippet
A direct answer box at the top of Google search, pulled from a single page — the original answer surface.
People Also Ask (PAA)
The expandable question cluster on Google; answering the full PAA set around a topic is core AEO work.
Structured Data
Schema markup that describes your content in a machine-readable format, so engines can extract and quote it accurately.
Schema
The vocabulary (Schema.org) used in structured data to define entities — articles, products, FAQs, organizations and more.
Entity
A distinct, disambiguated thing — a brand, person, place or concept — that engines represent in their knowledge graphs.
E-E-A-T
Experience, Expertise, Authoritativeness, Trustworthiness — Google's quality signals that also shape what AI engines choose to cite.
RAG
Retrieval-Augmented Generation — when an LLM pulls live documents to ground its answer, the mechanism behind most citation surfaces.
Hallucination
When a generative engine states something unsupported by a source; strong entity signals reduce the chance your brand is misrepresented.
Perplexity
An answer engine that cites sources inline for every response — a primary GEO measurement surface.
Semantic Search
Search that matches meaning and intent rather than exact keywords — the bridge between SEO and GEO.
