Glossary

# GEO glossary

The AI search terms you'll hear, explained in plain English for people who run a trade business.

By [Joseph](/about/), founder of Own Your GEO · Updated October 13, 2026

### GEO (generative engine optimization)

The work of getting your business named in answers written by AI tools like ChatGPT, Google AI, Gemini, Perplexity, Meta AI and Grok.

### AEO (answer engine optimization)

Another name for GEO. Some people also say AI SEO or LLM SEO.

### AI Overviews

The AI-written summary Google shows at the top of some search results.

### AI Mode

Google's chat-style search, where the whole result is an AI answer.

### LLM (large language model)

The type of AI behind ChatGPT, Gemini, Claude and similar tools.

### Query fan-out

When an AI tool turns one question into several web searches before it answers. It's why directories, reviews and your website all matter.

### Citation

A website an AI answer links to or draws from. Being cited, and being named on cited sites, both help.

### Mention rate

The share of AI answers that name your company for the questions you track.

### Share of voice

Your mentions as a share of all company mentions in the answers you track.

### Tracked question (prompt)

A fixed question asked to AI engines on a schedule so results can be compared over time.

### Like-for-like comparison

Comparing only the same questions on the same engines between two dates, so new questions don't inflate the result.

### Schema markup

Code on a web page that labels facts like your business name, services and FAQs so machines can read them.

### llms.txt

A plain-text file at the root of a website that summarizes it for AI tools.

### AI crawler

The bot an AI company uses to read websites, such as OAI-SearchBot, GPTBot, PerplexityBot or ClaudeBot.

### Google Business Profile

Your free business listing on Google Search and Maps, one of the sources AI cites most for local contractors.
