What is LLMS.txt?
LLMS.txt is an emerging web standard designed specifically for Large Language Models (LLMs) that was proposed by Jeremy Howard, co-founder of Answer.AI, in September 2024. As Howard explains, “We propose adding a /llms.txt file to websites that are designed for reading by language models, not just humans. llms.txt is a file that outlines the information that a model may want to retrieve (with links) when assembling context for LLM prompts relevant to a website.”
While robots.txt and sitemap.xml were designed for search engines, LLMS.txt is optimized for reasoning engines like ChatGPT, Claude, and Gemini. It provides information about a website to LLMs in a format they can easily understand and process.
Do Healthcare Practice Websites Need LLMS.txt?
Frankly, this is new and you’re probably fine for now. However, modern physician practices and hospital websites face unique challenges in information management that LLMS.txt can help address:
- Patient Information Access: Patients increasingly use AI assistants to find information about your practice, including services offered, physician credentials, and appointment scheduling procedures. LLMS.txt helps ensure they receive accurate information.
- Complex Service Offerings: Healthcare practices often provide multiple specialties, procedures, and treatment options across various locations. LLMS.txt can help AI systems quickly understand these offerings.
- Frequent Policy Updates: Healthcare practices regularly update policies on insurance acceptance, telehealth options, and COVID protocols. LLMS.txt can ensure AI systems reference the most current information.
- Educational Content Organization: Many practice websites include substantial patient education materials that could benefit from better AI accessibility.
- Location and Hours Clarity: Practices with multiple locations or specialized hours need AI systems to accurately represent this information to patients.
How is LLMS.txt Different from Robots.txt?
While both files exist in the root directory of a website, they serve fundamentally different purposes:
- Robots.txt: As Search Engine Land explains, “Robots.txt files work fine for crawlers and do not need changing for the purpose of LLMs.” Robots.txt controls how web crawlers access your site but doesn’t help LLMs understand your content.
- LLMS.txt: Howard explains that LLMS.txt helps overcome “context windows [that] are too small to handle most websites in their entirety” and the difficulty of “converting complex HTML pages with navigation, ads, and JavaScript into LLM-friendly plain text.”
Healthcare Practice-Specific Implementation of LLMS.txt
For physician practices and hospitals, an effective LLMS.txt implementation should include:
- Practice Overview: Clear description of your practice, specialties, and relationship to any larger healthcare network.
- Service Catalog: Links to detailed descriptions of services offered, procedures performed, and conditions treated.
- Physician Information: Links to provider profiles, credentials, and specialties.
- Patient Resources: Organized access to forms, educational materials, and preparation instructions.
- Location and Access: Detailed information about office locations, hours, and telehealth options.
Benefits for Healthcare Practice Websites
Implementing LLMS.txt offers several advantages for physician practices and hospitals:
- Improved Patient Access: As patients increasingly use AI assistants like ChatGPT and Google Gemini to find healthcare information, LLMS.txt ensures they receive accurate, current information about your practice.
- Reduced Phone Inquiries: When common questions about your practice can be accurately answered by AI systems, your staff spends less time answering basic phone inquiries.
- Better Representation in AI Responses: Without structured guidance, AI systems may provide outdated or incorrect information about your practice. LLMS.txt helps ensure accuracy.
- Enhanced Discovery of Services: Many patients may not know about all the services your practice offers. Better AI representation can improve awareness of your full capabilities.
- Competitive Advantage: As noted in Search Engine Land, “If you are playing to win, then you want your content to be that answer, as it is potentially worth a multitude of search engine searches.”
Do All Practice Websites Need LLMS.txt?
While LLMS.txt is not yet essential for all practice websites, it’s becoming increasingly valuable as patients rely more on AI assistants for healthcare information. Consider implementing LLMS.txt if:
- Your practice receives many basic questions that could be answered by AI
- You’ve noticed incorrect information about your practice appearing in AI responses
- Your practice offers multiple specialties or locations that may be confusing to represent
- You regularly update your services, providers, or policies
- Your practice has a substantial online educational component
Conclusion
LLMS.txt represents an innovative approach to making healthcare practice websites more accessible to AI systems. As patients increasingly rely on AI assistants to find healthcare information, implementing LLMS.txt can help ensure that information about your practice is accurately represented.
By creating an LLMS.txt file for your practice website, you can help shape how AI systems interact with your digital presence, ultimately improving information accuracy for patients and potentially reducing the administrative burden on your staff. For practices managed by MSOs and DSOs, this represents a straightforward way to enhance your digital presence and patient experience.
