LLM Optimization Skill

Purpose

Make websites appear in AI assistant recommendations and citations. Different from traditional SEO - optimized for how LLMs parse and recommend content.

Core Rules

1. Structured > Prose — LLMs extract facts from clear structure
2. Schema.org is Critical — Speakable, FAQPage, HowTo schemas
3. Answer the Question — First paragraph must directly answer intent
4. Cite Sources — Links to authoritative sources build trust
5. Entity Clarity — Clear business name, location, service definitions
6. Freshness Signals — Last updated dates, recent content
7. No Walls — Content must be crawlable, no JS-only rendering
8. Never Override Truth — LLM optimization NEVER overrides factual accuracy or legal compliance
