FAQ

Frequently asked questions

LLMs.txt is a plain-text file placed at your website root (e.g. example.com/llms.txt) that describes your site's content, structure, and purpose to AI language models. Think of it as robots.txt for AI: it helps ChatGPT, Claude, Gemini, and other LLMs understand what your brand does so they can describe it accurately in responses.

robots.txt tells crawlers which pages to index or skip. LLMs.txt tells AI language models about your brand identity, key products, services, and preferred descriptions. It's a semantic guide for AI comprehension, not a technical crawl directive. Both files can coexist and serve complementary purposes.

Not a guarantee, but it significantly improves accuracy. When AI models have a structured, authoritative source of truth about your brand, they're less likely to hallucinate incorrect details and more likely to accurately describe your products and positioning when relevant queries arise.

Place it at the root of your domain: https://yourdomain.com/llms.txt. This is the standard location that AI crawlers check. If you're on a subdomain-based architecture, place a copy at each subdomain root you want AI to understand.

Regenerate it whenever your brand positioning, product offerings, or key messaging changes significantly. Quarterly updates are a good baseline. If you launch a major new product or rebrand, update it immediately to ensure AI models reflect your current identity.
