GEO Glossary

Plain-English definitions of the generative engine optimization and AI-visibility terms you'll run into — from GEO and AEO to AI crawlers, llms.txt and share of voice.

AI Crawler

An automated bot that fetches web pages on behalf of an AI product — to train a model, index pages, or read a page live for a user.

AI Overview

Google's AI-generated answer shown at the top of some search results, which summarizes and cites sources instead of just listing links.

Read definition →

AI Visibility

How often and how favorably AI engines name your brand when people ask questions in your category — the AI-era equivalent of search ranking.

Read definition →

Answer Engine Optimization (AEO)

Optimizing your content to be the answer that AI engines and featured snippets give, rather than a link in a list.

Read definition →

Buying-Intent Prompt

A question a potential customer asks an AI engine when they're close to choosing — the prompts where being recommended matters most.

Read definition →

Citability

How easy a page is for an AI engine to quote and attribute — driven by clear answers, structure, schema and freshness.

Read definition →

Crawlability

Whether bots can fetch, read and index your pages. If AI can't crawl you, it can't cite you.

Read definition →

Generative Engine Optimization (GEO)

The practice of getting your brand recommended and cited by AI answer engines like ChatGPT, Perplexity and Gemini.

Read definition →

GPTBot

OpenAI's web crawler that gathers content to train and improve its models. Controlled via robots.txt.

Read definition →

Grounding

When an AI engine bases its answer on retrieved sources rather than only its training data — the mechanism that produces citations.

Read definition →

llms.txt

A markdown file at your site root that tells AI engines what your site is and which pages matter most.

Read definition →

Presence Rate

Of all the relevant prompts you track, the share of AI answers that name your brand at all.

Read definition →

Retrieval-Augmented Generation (RAG)

A technique where an AI model retrieves relevant documents at answer time and generates its response from them — the basis for cited AI answers.

Read definition →

robots.txt

A file at your site root that tells crawlers — including AI crawlers — which parts of your site they may access.

Read definition →

Share of Voice (AI)

How often AI names your brand versus each competitor across the prompts you track.

Read definition →

Structured Data (Schema)

Machine-readable markup — usually JSON-LD — that describes your content so engines parse and attribute it precisely.
