What Is llms.txt and Does Your Business Website Need One?
What llms.txt is, what goes in the file, a simple example, and whether a local business website needs one. Plus what matters more for AI visibility.
Short answer: llms.txt is a proposed text file placed at yoursite.com/llms.txt that gives AI tools a short, plain summary of your site and links to your most important pages. It is not an official standard, and Google has said it does not use it for Search. For a local business it is optional and low effort, but it will not replace good pages, reviews and consistent listings.
What goes in an llms.txt file
- Your business name and a one-paragraph summary of what you do and where
- Links to key pages: services, service areas, pricing, contact
- Short notes on what each page covers
