What is llms.txt and does my small business actually need one?

If you've heard "llms.txt" mentioned and want to know what it actually is — without the agency jargon — this is the explainer.

The 30-second answer

llms.txt is a plain text file placed at the root of your website (e.g. https://yourbusiness.com/llms.txt) that tells AI language models — ChatGPT, Claude, Gemini, Perplexity, and emerging crawlers — what your business is, what you offer, and how to read your site content.

It's the AI-era equivalent of robots.txt, except instead of just telling crawlers where to go, it gives them structured business context they can use when answering customer questions about your category.

Why it matters

When someone asks ChatGPT "best dental practice in Newport Beach," the model has to decide which businesses to mention. Without an llms.txt, it parses your site like every other site — slowly, sometimes incorrectly, often missing key details. With one, it has a clean, structured summary of your business ready to extract.

Early adopters benefit disproportionately. In 2026, less than 1% of small business websites have an llms.txt file. The ones that do are dramatically over-cited in AI answers relative to their market share.

What goes in an llms.txt file

1. Business identity — name, type, location, year founded, founder
2. Contact info — phone, email, website, hours
3. Services with prices — full list with descriptions
4. Service area — cities you serve
5. Vocabulary — what industry terms you use (this helps the model match queries)
6. Key pages — URLs to your most important pages with one-line descriptions
7. FAQs — common questions with concise answers (40-60 words each)

Copy-paste template

Where to put it

The file must be accessible at https://yourbusiness.com/llms.txt — same level as robots.txt and sitemap.xml. How you upload it depends on your platform:

• WordPress: upload via FTP, cPanel file manager, or a plugin like WPCode
• Squarespace: Settings → Advanced → Code Injection (or contact support to upload root files)
• Webflow: Project Settings → Custom Code → Head section won't work — you need to upload via Webflow Hosting Asset Manager or use a Cloudflare Worker
• Wix: Wix doesn't expose root file uploads — you'll need to add a redirect rule or use Velo
• Netlify / Vercel / static hosting: drop the file in your public/ or root directory and deploy

How to know it's working

Visit https://yourbusiness.com/llms.txt in a browser. If you see your text, AI crawlers can see it too.

For deeper validation, query ChatGPT or Perplexity 2-3 weeks after deployment with category-specific questions about your business or service area. If you start showing up where you previously didn't, it's working.
