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

llms.txt is a plain text file at the root of your website (like robots.txt) that gives AI models a structured summary of your business — services, locations, hours, specialties. Without it, AI assistants have to guess what you do by crawling your site, and they often get it wrong or skip you entirely. Adding one takes 10 minutes and immediately makes your business readable to every major AI system.

How do I know if AI assistants are recommending my business?

Ask them directly. Open ChatGPT, Claude, or Google Gemini and type 'Who are the best [your service] companies in [your city]?' If you're not in the response, you have an AI visibility problem. Our free audit at vibetokens.io/start runs this check automatically across multiple AI systems and tells you exactly where you stand.

Is AI visibility different from regular SEO?

Yes. Traditional SEO optimizes for Google's search index — keywords, backlinks, page speed. AI visibility optimizes for how language models understand and recommend your business. A company can rank #1 on Google and still be completely invisible to ChatGPT. The two disciplines overlap (schema markup helps both), but AI visibility requires additional steps like llms.txt, FAQ schema, and ensuring AI crawlers aren't blocked in robots.txt.

AI Visibility for Local Business — The SEO Layer Nobody's Talking About

Here's something that should worry every local business owner: when a potential customer asks ChatGPT "who's the best plumber in Austin?" — your company probably isn't in the answer.

Not because you're bad at what you do. Because the AI doesn't know you exist.

We've been so focused on Google rankings for the last 20 years that we missed the shift happening underneath. AI assistants are becoming the new front door for local business discovery. And the rules for getting found are completely different.

The New Discovery Layer

Google still matters. Nobody's saying otherwise.

But the way people find businesses is fragmenting. ChatGPT has over 200 million weekly active users. Claude is growing fast. Siri, Alexa, and Google Assistant handle billions of voice queries. When someone asks "who should I hire to clean my gutters?" — they're increasingly asking an AI, not typing into a search bar.

Here's the problem: these AI systems don't use Google's index. They use their own training data, real-time web crawling, and structured signals to decide which businesses to recommend. If your website doesn't speak their language, you're invisible.

We call this AI visibility — and it's the SEO layer nobody's talking about yet.

What Is llms.txt (And Why It Matters)

You know robots.txt — the file that tells search engine crawlers what they can and can't access on your site. It's been standard for decades.

llms.txt is the AI equivalent. It's a plain text file that sits at your domain root (yourbusiness.com/llms.txt) and gives AI models a structured, human-readable summary of your business.

Think of it as your elevator pitch to every AI system on the internet, all at once.

A good llms.txt includes:

Your business name and what you do
Service areas and locations
Core services with brief descriptions
Hours, contact info, specialties
What makes you different

Without it, AI models have to piece together your identity from whatever they can crawl — which might be outdated cached data, a thin About page, or nothing at all. With it, you're handing them a clean briefing document.

The businesses that add llms.txt now are the ones AI assistants will recommend six months from now. It's that simple.

How AI Assistants Find (Or Skip) Local Businesses

When ChatGPT or Claude answers a question about local services, they pull from several sources:

Training data — whatever was in their training set (often 6-18 months old)
Real-time web access — crawling your site, reading structured data
Schema markup — JSON-LD that explicitly tells machines what your business is
Third-party signals — directories, reviews, citations that mention you

If your site blocks AI crawlers in robots.txt, you've cut off source #2 entirely. If you have no schema markup, source #3 is empty. If your site is thin on content, source #1 probably missed you during training.

Most local businesses fail on all four counts. They built a website for humans (good) and never considered that machines need to read it too (problem).

The 5-Point AI Visibility Check

At VibeTokens, we built this into our free brand audit. Every business that runs through our audit at /start gets checked on five AI visibility signals:

1. llms.txt File

Does your site have one? Is it well-structured? Does it accurately describe your business? Most sites score zero here because the standard is brand new.

2. Schema Markup

Are you using LocalBusiness, Service, and Organization schema? This is the structured data that Google AND AI systems use to understand what you do. It's the bridge between traditional SEO and AI visibility.

3. FAQ Schema

Do you have FAQ markup on your key pages? This is huge for AI assistants because it gives them pre-formatted question-and-answer pairs they can use directly in responses. When someone asks "how much does a roof inspection cost in Denver?" — FAQ schema is how your answer gets surfaced.

4. AI Crawler Access

Is your robots.txt blocking AI crawlers? Many default WordPress configurations block bots like GPTBot, ClaudeBot, and others. If the crawlers can't reach your content, the AI can't recommend you. We check whether your robots.txt explicitly allows or denies the major AI user agents.

5. LLM Knowledge Check

This is the real test. We ask a language model directly: "What do you know about [your business]?" If the answer is vague, wrong, or empty — that's your baseline. That's what potential customers are seeing when they ask AI about you.

What You Can Do About It Today

The good news: AI visibility is a solvable problem, and the window to get ahead of competitors is wide open right now.

Start with llms.txt. Create a plain text file, write a clean summary of your business, and upload it to your site root. This takes 10 minutes and has an outsized impact.

Add schema markup. If you don't have LocalBusiness and Service schema on your site, add it. This helps Google AND every AI system simultaneously. It's the highest-leverage technical SEO task you can do in 2026.

Check your robots.txt. Make sure you're not blocking GPTBot, ClaudeBot, or other AI crawlers. If you are, you're actively hiding from the fastest-growing discovery channel in business.

Add FAQ content. Write real questions and answers about your services, pricing, and process. Mark them up with FAQ schema. AI assistants love this format because it maps directly to how people ask questions.

Test your AI presence. Open ChatGPT and Claude. Ask them about your business by name. Ask them who the best [your service] is in [your city]. The answers will tell you exactly where you stand.

The Window Is Now

Here's the thing about AI visibility: it's early. Most of your competitors haven't even heard of llms.txt. They're not thinking about whether ChatGPT knows their business exists.

That means every step you take right now compounds. The businesses that establish AI visibility in 2026 will own that channel the same way early SEO adopters owned Google in 2010.

Want to know where you stand? Run a free audit at /start. It checks all five AI visibility signals, compares you against your top competitor, and tells you exactly what to fix — in about two minutes.

The future of local business discovery is AI-first. The question is whether your business will be visible when customers ask.
