The LLMO Framework

Open research initiative on AI retrieval, grounding visibility, and LLM-native web architecture. Backed by reproducible research. Implemented in production. Open source.

The Open LLMO Research Initiative is an independent research initiative on AI-native retrieval, grounding visibility, and LLM-oriented information architecture. Outputs include experimental specifications (drafts), open-source tooling, and reproducible benchmarks.

Focus areas:

  • AI retrieval optimization
  • Grounding visibility
  • Citation systems and reference attribution
  • LLM-native web architecture
  • Reproducible benchmark methodologies

Founded and maintained by Ken Imoto, author of multiple books on LLMO and harness engineering. The LLMO Framework below is the Initiative’s first published reference artifact.

1. Knowledge Clarity

Clear, factual, unambiguous content that AI can understand and summarize accurately.

2. Structural Formatting

Machine-readable structure: Markdown, JSON-LD, semantic HTML, llms.txt.

3. Retrieval Signals

llms.txt, /ai/ directory, robots.txt, sitemap — help AI systems find you.

4. Authority Signals

Cross-platform presence, publications, verifiable expertise and credentials.

5. Citation Signals

Primary sources, statistics, dates, and references that AI prefers to cite.

6. Coherence Signals

Same fact tells the same story across HTML, JSON-LD, Markdown, llms.txt — single source of truth.

LLMO (Large Language Model Optimization) is the practice of optimizing web content so that AI systems can accurately discover, understand, and cite it. New here? Start with What is LLMO? for the full definition and how it differs from SEO, AEO, and GEO.

As AI-powered search becomes mainstream, traditional SEO alone is no longer sufficient. Users get answers from ChatGPT, Claude, Gemini, and Perplexity — not just Google. LLMO ensures your content is discoverable across all AI systems.

LLMO is the umbrella framework that encompasses AEO (Answer Engine Optimization) and GEO (Generative Engine Optimization), providing a broader, implementation-focused reference for all LLM interactions.

The Framework’s published artifacts are above. Below is reference work that applies the Framework to specific verticals.

  • AI Native MEO — local business / map-search vertical. Tracks the Framework with practitioner-facing articles on Google Business Profile as JSON-LD, NAP entity resolution, and how each AI engine cites local data. Start with LLMO vs GEO vs AEO for local business.
