Your Website is Invisible to ChatGPT. Here's the 5-Minute Fix.
ChatGPT now recommends businesses to millions of users every day.
Plumbers. Web developers. Accountants. Restaurants.
People are asking AI "find me a good web developer near me" and AI is answering with specific business names.
Is yours one of them?
Probably not. And it's not your fault.
Why Traditional SEO Doesn't Work for AI
You've done everything right.
Fast website. Good meta tags. Google Business Profile. Sitemap submitted.
But ChatGPT still doesn't know you exist.
That's because AI search works differently from Google. It doesn't just read your meta description. It needs to understand your business what you do, who you serve, where you are.
Most websites give AI tools absolutely nothing to work with.
The Fix llms.txt
There's a file called llms.txt.
Think of it as robots.txt but for AI instead of Google.
You create it once, add it to your website, and suddenly ChatGPT, Perplexity, and Gemini know exactly what your business is about.
Here's the basic structure:

That's it.
Does it Actually Work?
I added llms.txt to a web studio site devndespro.com — and within weeks both ChatGPT and Perplexity started recommending it for relevant searches.
The site was only a few weeks old at the time.
No ads. No viral posts. No expensive backlinks.
Just one simple file.
Make it Even Stronger
Pair llms.txt with these two things for maximum AI visibility:
1. FAQ content on your pages
AI tools love Q&A format. Add a simple FAQ section to your homepage answering questions like "What does your business do?" and "Who do you serve?"
2. Schema markup
Add Organization and LocalBusiness JSON-LD schema to your homepage. This gives AI tools structured data about your business in a format they understand perfectly.
The Opportunity is Wide Open
Google SEO took 20 years to become competitive. Millions of websites are fighting for the same keywords.
AI search is still wide open in 2026.
The businesses that optimise for it now will have a massive advantage over those who wait another year.
Your llms.txt file is step one. It takes 5 minutes.
There is no reason not to do it today.
