Just like robots.txt tells search engines how to crawl your site, llms.txt tells AI crawlers about your brand and content. It's a simple but powerful way to improve your visibility in AI-generated answers.
What is llms.txt?
llms.txt is a markdown file placed at the root of your website (yoursite.com/llms.txt) that provides AI crawlers with structured information about your brand. Think of it as your elevator pitch to AI.
The Official Format
```markdown
# Your Brand Name
> Brief description of what you do
About
Detailed information about your company, mission, and values.
Key Pages
Contact
```
Why llms.txt Matters
1. AI Crawlers Are Real
Companies like Perplexity, Anthropic, and OpenAI all have web crawlers that index content. Giving them a structured overview helps them understand your site.
2. Context Over Keywords
Unlike search engines, AI benefits from understanding context. llms.txt lets you explain your brand in your own words.
3. First-Mover Advantage
llms.txt is still emerging. Sites that adopt it now are ahead of competitors who haven't heard of it yet.
How to Create Your llms.txt
Option 1: Manual Creation
Create a markdown file and host it at /llms.txt on your server.
Option 2: Use ADvisor
ADvisor can automatically generate an llms.txt file based on your site's content, keywords, and performance data. It's optimized for AI visibility.
Best Practices
1. Keep it Current - Update your llms.txt when you add major content
2. Be Concise - AI doesn't need fluff, it needs facts
3. Include Key URLs - Direct crawlers to your most important pages
4. Add Contact Info - Make it easy for AI (and humans) to reach you
Implementing llms.txt in Next.js
```typescript
// app/llms.txt/route.ts
export async function GET() {
const content = `# Your Brand
> Your tagline here
About
Your description...
`;
return new Response(content, {
headers: { 'Content-Type': 'text/markdown' }
});
}
```
