llms.txt: The One-File Signal That Tells AI Who You Are
A single llms.txt file gives AI crawlers a clean, authoritative summary of your business. Here's the exact format and why it's the fastest AEO win.
What is llms.txt?
llms.txt is a plain-text file placed at the root of your website (yoursite.com/llms.txt) that gives AI crawlers a clean, structured summary of your business: who you are, what you do, where you operate, and what you want to be known for. Think of it as a curated elevator pitch written specifically for language models.
Why it's the fastest AEO win
Most websites force AI crawlers to piece together your identity from scattered pages, images, and JavaScript. An llms.txt file hands them the answer directly — no guessing, no misinterpretation. Because it's a single static file, it can be created and indexed within days, making it one of the highest-leverage, lowest-effort improvements in any AEO program.
What goes in it
A strong llms.txt includes your business name and one-line description, your core services, your location and service area, your differentiators and credentials, and links to your most authoritative pages. It should read like the answer you'd want an AI to give when someone asks about your business.
The catch
llms.txt is a signal, not a guarantee. It works best alongside schema markup, consistent citations, and AI-readable content. On its own it helps; combined with the rest of an AEO program, it compounds. We publish and maintain llms.txt for every Click Elevate client as part of the standard setup.
