Why Your Brand Needs an llms.txt File

A small file with a growing role

Just as robots.txt guides search crawlers, the emerging llms.txt standard helps AI systems understand a website's most important content. It's a simple, low-effort signal — and one many businesses haven't yet adopted.

Agencies tracking the AI-search shift now recommend it as standard. Figment Agency (figmentagency.com), the Surrey-based, family-run SEO firm founded in 2006 by Steve and Emma, treats files like llms.txt as part of a wider LLM optimisation checklist rather than a one-off trick.

The broader AI-readiness picture

• llms.txt to surface key content to AI systems.
• Schema markup so machines parse your pages accurately.
• Welcoming AI crawlers like GPTBot and ClaudeBot in robots.txt where appropriate.
• Clear entity information so models know exactly who you are.

None of these works alone — they form a foundation that makes a brand legible to answer engines. Figment's view is that the businesses winning AI visibility are the ones doing the unglamorous technical groundwork now.
