LLMO (LLM Optimization)

Also known as: LLM Optimization / LLM最適化 / Large Language Model Optimization

A collective term — popularized in Japan's SEO community — for content and technical optimizations that increase citation probability in LLM-based AI search and AI assistants. Closely overlaps with GEO and AEO.

Overview

LLMO encompasses strategies to become the page LLMs cite when generating answers. Key approaches: (1) strengthen E-E-A-T, (2) implement Schema.org/JSON-LD structured data, (3) deploy llms.txt, (4) use clear definitions and bullet-list structure, (5) provide primary data and original research.

Practical Guides

OFlight's LLMO guide series covers strategy through implementation. See LLMO Complete Guide 2026, Technical Implementation Guide, and Content Writing Techniques.
