Introducing llms.txt: A New Standard for AI-Driven Search Visibility

As generative AI reshapes how people discover and consume information, businesses need tools to ensure their content remains accessible, accurate, and aligned with their brand in AI-generated responses.

Enter llms.txt—a straightforward yet powerful protocol that gives website owners control over how their content is used by large language models (LLMs). Similar to how robots.txt guides traditional search engines, llms.txt lets brands manage how AI systems crawl, index, and reference their content.

What Is llms.txt?

llms.txt is a proposed web standard that allows publishers to specify how their content should be treated by generative AI models. By placing a llms.txt file at the root of your domain (e.g., attensira.com/llms.txt), you can provide clear instructions to AI crawlers and LLM providers about content usage—whether it can be indexed, summarized, cited, or excluded entirely.

This initiative is gaining momentum as AI-generated responses become integral to platforms like ChatGPT, Gemini, and Perplexity.

Why llms.txt Matters for Brands?

Protect Brand Integrity

1. Generative AI may summarize or reframe your content without preserving its context or nuance. llms.txt lets you set boundaries to safeguard your messaging and intent.

Regain Content Ownership

1. With LLMs pulling data from across the web, it’s crucial to have a mechanism to dictate how your content can or cannot be used. llms.txt gives you that control.

Enhance Content Attribution

1. Properly configured, llms.txt can promote responsible citation practices, ensuring your brand is credited in AI-generated outputs.

Boost AI Visibility

1. Rather than blocking access, llms.txt can be used to invite AI crawlers—on your terms. You can design your file to allow responsible access while maintaining compliance with your brand’s standards.

How llms.txt Works

• It’s a plain-text file hosted at your domain’s root.
• Uses standardized syntax to define which bots or models can access your site.
• Allows or restricts actions like indexing, summarizing, or citing.
• Functions similarly to robots.txt, but tailored for LLMs and generative AI engines.

Example:

User-agent: GPTBot
Allow: /

User-agent: AttensiraBot
Allow: /

User-agent: ClaudeBot
Disallow: /

User-agent: *
Disallow: /private/

This example permits OpenAI’s GPTBot and Attensira's Bot to crawl the site, blocks ClaudeBot, and restricts all bots from accessing the /private/ directory.

Who Should Use llms.txt?

Organizations that:

• Publish original online content.
• Seek control over how AI platforms interact with their content.
• Prioritize brand reputation, accuracy, and proper attribution.
• Invest in Generative Engine Optimization (GEO).
