3BL LLM Visibility: AI Content Indexing & Discovery


llm.txt is a lightweight Markdown file that helps AI systems understand, prioritize, and surface your content accurately.

What is llm.txt?

A sitemap built for the AI era.

Traditional sitemaps work fine for search engines. But AI agents like ChatGPT, Perplexity, and Claude prefer clean, structured text — not tag-heavy HTML.

llm.txt tells AI systems:

  • What your organization does
  • Which content is most important
  • Where to find it

How it works for your content:

When a stakeholder asks an AI assistant about your sustainability commitments or community impact, that AI pulls from available sources. llm.txt ensures your published content is legible, authoritative, and prioritized.

Every story published now becomes more legible to AI systems increasingly mediating how stakeholders discover and evaluate brands. That compounds over time.

llm.txt is now live for all client content. Reach out to your Client Success Manager for more information.
