Reports from Search Engine Journal, Search Engine Roundtable, and AI industry blogs in late April 2026 confirm that Perplexity AI and Anthropic's Claude have publicly acknowledged crawling llms.txt files, and Google has signaled experimental support.

**Why AI Search Engines Are Skipping Your Website**

AI-powered answer engines like Perplexity, ChatGPT, and Claude pull business information from websites they can quickly read and understand. Without a file called llms.txt placed in your website's root directory, AI crawlers often skip your site entirely or pull inaccurate details about your business. A missing llms.txt file means your competitors get cited in AI answers, and you do not.

**What an llms.txt File Does**

An llms.txt file gives AI models a plain-language summary of who you are, what you do, and which pages matter most. Think of the file as a direct briefing document written specifically for AI systems. Perplexity, Claude, and several other major platforms now actively read llms.txt files when generating answers to user queries.

**What to Include in Your llms.txt File**

A basic llms.txt file should cover the following:

- Your business name, location, and primary service or product
- A 2 to3-sentencee plain-language description of what your business does
- Links to your most important pages (services, about, contact)
- Your geographic service area written in plain text

Keep the file under 500 words, and update it whenever your services change.

**Your Next Step**

Open your website's root directory today, create a plain text file named llms.txt, and add a clear description of your business, your services, and your location using the format above.
