llms.txt is the new standard for telling AI language models exactly what your business does, who you serve, and what content to prioritize. Here's how to create yours.
llms.txt is a plain-text file placed at yourdomain.com/llms.txt that gives AI language models a structured summary of your website — similar to how robots.txt guides crawlers, but specifically designed for LLMs like ChatGPT, Claude, and Perplexity.
Your llms.txt should contain: your business name and one-sentence description, a short about paragraph, a list of your services with brief descriptions, your service areas, contact information, links to your key pages, and your credentials and trust signals (licenses, years in business, review count).
When AI engines crawl your site, they often struggle to understand the full picture — especially for local businesses with complex service offerings. llms.txt gives them a clean, structured summary they can use immediately. Early adopters are seeing measurable improvements in AI citation accuracy.
