AEO and GEO terminology has developed rapidly alongside the underlying technology, and staying comfortable with current vocabulary helps marketers engage confidently with this fast-moving area, alongside the more established terms covered in our general SEO glossary.

Foundational AEO and GEO terms

  • AEO (Answer Engine Optimization): optimising for direct answer selection by AI-powered systems.
  • GEO (Generative Engine Optimization): structuring content for accurate retrieval and citation by generative AI.
  • RAG (Retrieval-Augmented Generation): the technical process where an AI model retrieves relevant content before generating a response.
  • LLM citation: being referenced as a source within an AI-generated response.

Platform-specific terms

  • AI Overview: Google's AI-generated summary feature above traditional search results.
  • AI Mode: Google's more conversational, multi-turn AI search experience.
  • Copilot: Microsoft's AI assistant, drawing on Bing's search infrastructure.
  • GPTBot, ClaudeBot: specific AI crawler user agents, relevant to robots.txt configuration.

This vocabulary is still settling — some of these terms may consolidate or shift meaning over the next few years, but understanding them now gives you a real head start on a genuinely new area of marketing practice.

Content structure terms specific to this discipline

  • Content chunking: structuring content into self-contained, retrievable sections.
  • Answer-first content: leading with a direct answer before supporting context.
  • Entity consistency: presenting identity signals identically across every platform.
  • llms.txt: an emerging file standard for signalling AI crawler permissions.

Frequently asked questions

Is this terminology likely to change significantly over time?

Yes, this is a genuinely new and fast-evolving area — some terms may consolidate, and new terminology will likely emerge as the underlying platforms and technology continue developing.

Do I need to understand every term here to build an effective AEO/GEO strategy?

No, the practical tactics matter more than exhaustive terminology knowledge — this glossary is a reference to support clearer communication, not a prerequisite checklist.

Where can I find the most current terminology as this field evolves?

Established industry publications covering AI search specifically, alongside the platforms' own documentation where available, remain the most reliable ongoing sources as terminology continues to develop.
