How llms.txt and Schema Markup Make Your Site AI-Discoverable
AI crawlers don't read websites the way humans do. They look for structured signals that say: "This is a real business, here's what they do, and here's proof."
Two of the most important signals are llms.txt and schema markup. Used together, they turn a generic website into an AI-readable business profile.
What llms.txt Does
llms.txt is a plain text file at your root that tells AI crawlers what your business does, which pages matter most, and how to contact you.
Think of it as a cheat sheet for AI. Instead of guessing from scattered pages, AI gets a concise summary.
What Schema Markup Does
Schema markup is structured data embedded in your HTML. For local businesses, LocalBusiness schema tells AI:
- Business name, address, phone
- Service areas and hours
- Services offered
- Reviews and ratings
Without schema, AI has to infer business details from normal page text. With schema, AI gets machine-readable facts.
How They Work Together
llms.txt gives AI the overview. Schema gives AI the details. Together, they remove ambiguity.
A typical local business website might have both missing. Adding them usually takes minutes, not weeks.
Quick Implementation
- Create
llms.txtat your domain root with business name, services, key pages, and contact info. - Add LocalBusiness schema to homepage and service pages.
- Make sure GBP name, address, and phone match schema exactly.
- Test with Google Rich Results Test and a SottoVox scan.
TL;DR
llms.txt tells AI what you do. Schema tells AI where you are, what you offer, and why to trust you. Together, they're the fastest technical unlock for local AI visibility.
