# llms.txt Creator

Create standardized llms.txt files that help AI systems discover, understand, and cite your content accurately.

## What is llms.txt?

The llms.txt file is a standardized markdown document hosted at a website's root path (e.g., `https://example.com/llms.txt`). It serves as a curated index for LLMs, providing:

- Concise summaries of the site's purpose
- Critical contextual details about the brand/product
- Prioritized links to machine-readable resources

Think of it as the third layer next to existing files:
- `robots.txt` - explains what crawlers may access
- `sitemap.xml` - lists URLs for indexing
- `llms.txt` - tells LLMs which content is most important and where to find clean versions

## File Structure

Follow this standardized schema:

```markdown
# [Brand/Company Name]

> [One-sentence description of what the company/product does]

Key terms: [Important concepts, product names, technologies]

## [Section Name]

- [URL to markdown resource] — [Brief description]
- [URL to markdown resource] — [Brief description]

## Optional

- [URL to secondary resource] — [Brief description]
```

## When Creating llms.txt

### 1. Audit High-Value Content

Identify the pages that matter most for AI-driven questions:

- Core documentation and API references
- Pricing, plans, and usage rules
- Policies (returns, SLAs, compliance)
- Critical onboarding or integration guides

**Ask:** "If someone asked an AI about this topic, which pages should it read first?"

### 2. Create Clean Markdown Versions

llms.txt works best when linking to content that is:

- Free of navigation clutter and cookie banners
- Structured with headings, code blocks, and short paragraphs
- Focused on a single topic or task

For each priority page, consider creating a `.md` version at the same path (e.g., `/docs/api.md` alongside `/docs/api`).

### 3. Organize by Section

Standard sections include:

| Section | Purpose |
|---------|---------|
| **Docs** | Technical documentation, API references, tutorials |
| **Product** | Product descriptions, features, pricing |
| **Policies** | Terms, privacy, return policies, compliance |
| **Support** | FAQs, troubleshooting, contact information |
| **Optional** | Secondary content that can be skipped if context is limited |

### 4. Write Clear Descriptions

Each link should have a brief description (10-20 words) explaining:
- What the page contains
- When/why an AI should reference it

## Example: SaaS Company

```markdown
# Superlines

> AI Search Intelligence platform that helps brands track, optimize, and grow their visibility in AI Search across ChatGPT, Perplexity, Gemini, and Google AI Mode.

Key terms: GEO, Generative Engine Optimization, AI Search, Brand Visibility, Citation Rate, AI Share of Voice, MCP Server.

## Best Practices

1. **Keep it curated, not comprehensive** - Only include your most important pages
2. **Update when docs change** - Stale llms.txt reduces trust
3. **Use consistent terminology** - Match terms used in your actual content
4. **Test with LLMs** - Ask ChatGPT about your product and check if responses improve
5. **Link to clean markdown** - Avoid linking to pages heavy with JavaScript/navigation

## Common Mistakes to Avoid

- Listing every page on your site instead of curating
- Linking to noisy HTML full of layout code and ads
- Forgetting to update when documentation changes
- Using vague descriptions that don't help AI understand content purpose
