What is LLMO?

LLMO (Large Language Model Optimization) is the practice of optimizing web content so that Large Language Models can accurately discover, understand, and cite it in their responses.

When users ask AI assistants questions about your business, products, or expertise, the AI may:

  • Not mention you at all
  • Provide outdated information
  • Attribute your work to someone else
  • Give inaccurate descriptions

LLMO solves this by making your content AI-discoverable.

LLMO is an umbrella concept that includes:

  • AEO (Answer Engine Optimization): Focuses on being selected as the answer in AI-powered search. Coined by Jason Barnard (2018).
  • GEO (Generative Engine Optimization): Academic framework for optimizing visibility in generative search engines. Introduced by researchers at Princeton University (2023).

LLMO encompasses both approaches while providing a broader, implementation-focused framework for all LLM interactions — not just search engines.
