# 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

## LLM Crawlers to Support

| LLM | Crawlers | Notes |
|-----|----------|-------|
| OpenAI/ChatGPT | GPTBot, OAI-SearchBot, ChatGPT-User | GPTBot = training, others = real-time |
| Google Gemini | Google-Extended | robots.txt control token, not a distinct UA |
| Perplexity | PerplexityBot, Perplexity-User | Bot = indexing, User = real-time fetch |
| Claude | ClaudeBot, Claude-User, Claude-SearchBot | Official Anthropic crawlers |
| Microsoft Copilot | Bingbot | Uses Bing's crawler |

<p class="lead">

</p>

  <dl>
    <dt>Service Area</dt><dd itemprop="areaServed">[Areas]</dd>
    <dt>Price Range</dt><dd itemprop="priceRange">[Range]</dd>
  </dl>
</aside>

<!-- 3. FAQ Section (critical for LLM) -->

</section>
```
