LLMO Quickstart: Implement in 30 Minutes

You can make your site AI-discoverable in 30 minutes with three files. This guide covers the minimum viable LLMO implementation.

The Three Essential Files

File	Purpose	Time
`robots.txt`	Allow AI crawlers to access your site	5 min
`llms.txt`	Provide AI with a structured summary of your site	15 min
JSON-LD `<script>`	Give AI structured data about your content	10 min

Step 1: robots.txt for AI Crawlers (5 min)

Most sites already have a robots.txt. Add explicit Allow rules for AI crawlers:

User-agent: *
Allow: /

User-agent: GPTBot
Allow: /

User-agent: ClaudeBot
Allow: /

User-agent: Google-Extended
Allow: /

User-agent: PerplexityBot
Allow: /

Sitemap: https://yoursite.com/sitemap.xml

Why explicit Allow? Some hosting platforms and CDNs block AI crawlers by default. Explicit rules prevent accidental blocking.

Known AI Crawlers

Crawler	Operator	Purpose
GPTBot	OpenAI	ChatGPT, web browsing
ClaudeBot	Anthropic	Claude web search
Google-Extended	Google	Gemini, AI Overviews
PerplexityBot	Perplexity	Perplexity search
Amazonbot	Amazon	Alexa, product search
CCBot	Common Crawl	Training data collection

Step 2: Create llms.txt (15 min)

The llms.txt file (proposed by Jeremy Howard at llmstxt.org) gives AI systems a structured summary of your site.

Place this file at your site root: https://yoursite.com/llms.txt

Template

# Your Site Name

> One-sentence description of what your site does.

## What We Do

A brief paragraph explaining your core offering, expertise, or purpose.
Use plain language. Avoid marketing jargon.

## Key Facts

- Founded: [year]
- Team: [size or key people]
- Location: [if relevant]
- Specialization: [your core expertise]

## Products / Services

- **Product A**: Brief description
- **Product B**: Brief description

## Links

- Website: https://yoursite.com
- Documentation: https://yoursite.com/docs
- GitHub: https://github.com/yourorg
- Contact: https://yoursite.com/contact

Best Practices

Lead with facts, not marketing. “We build Android apps with AI automation” beats “We leverage cutting-edge synergies.”
Include structured data. Tables, lists, and key-value pairs are easier for AI to parse than prose paragraphs.
Keep it under 2,000 words. Concise summaries are more likely to be ingested fully.
Update regularly. AI systems re-crawl periodically. Stale llms.txt means stale AI responses.

Step 3: JSON-LD Structured Data (10 min)

Add a JSON-LD script to your homepage <head>. This helps AI understand your entity type, relationships, and key attributes.

Organization Schema

<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@type": "Organization",
  "name": "Your Company",
  "url": "https://yoursite.com",
  "description": "What your company does in one sentence.",
  "founder": {
    "@type": "Person",
    "name": "Founder Name"
  },
  "sameAs": [
    "https://github.com/yourorg",
    "https://linkedin.com/company/yourorg",
    "https://x.com/yourorg"
  ]
}
</script>

Article Schema (for blog posts)

<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@type": "Article",
  "headline": "Your Article Title",
  "author": {
    "@type": "Person",
    "name": "Author Name",
    "url": "https://authorsite.com"
  },
  "datePublished": "2026-01-15",
  "publisher": {
    "@type": "Organization",
    "name": "Your Company"
  }
}
</script>

Which Schema Types to Use

Content Type	Schema	Priority
Homepage	Organization or Person	High
Blog posts	Article or BlogPosting	High
Products	Product	High
FAQ pages	FAQPage	Medium
Documentation	TechArticle	Medium
Books	Book	Medium

Verify Your Implementation

After deploying, check:

robots.txt: Visit https://yoursite.com/robots.txt and confirm AI crawlers are allowed
llms.txt: Visit https://yoursite.com/llms.txt and verify the content is accurate
JSON-LD: Use Google’s Rich Results Test or view page source to confirm the script tag is present
AI test: Ask ChatGPT or Perplexity about your site/product and observe the response
