What is an llms.txt File, and Why Does Your Cincinnati Business Website Need One?

Introduction: Speaking to the Bots

In the age of AI, your website has a new audience: intelligent machines. Large Language Models (LLMs) like Google’s Gemini and OpenAI’s ChatGPT are constantly crawling the web, summarizing content, and answering user questions.

They are forming an opinion about your business right now. The question is, are you controlling the narrative?

Just as a robots.txt file tells search engine crawlers which pages to visit, a new standard is emerging to tell AI models how to think about your website. It’s called llms.txt, and it’s your brand’s new instruction manual for artificial intelligence. For businesses here in the Cincinnati and Northern Kentucky region, this simple file is a powerful tool to ensure your local identity is clear and accurate.

What Exactly is an llms.txt File?

Think of llms.txt as a cheat sheet for AI. It’s a simple text file that you place in your website’s main directory. Inside this file, you provide clear, concise instructions about your business, including:

• Who you are: Your company’s mission and identity.
• What you do: Your core services and value proposition.
• Who you serve: Your target audience and service area.
• Your brand voice: The tone and personality you want to convey.

By creating this file, you’re not leaving the AI to guess. You are explicitly telling it how to interpret and represent your brand, ensuring accuracy and consistency across different AI platforms.

Why llms.txt is a Game-Changer for Your Business

Implementing this file isn’t just a technical exercise; it’s a strategic business move. Here’s why it matters:

1. Control Your Brand Narrative: Without guidance, an AI might misinterpret a nuanced product description or summarize your company’s history incorrectly. llms.txt ensures the AI’s summary aligns with your official brand messaging.
2. Boost Local SEO: This is huge for businesses targeting a specific geographic area. In your llms.txt, you can explicitly state that you are “a Burlington, KY-based agency serving the Greater Cincinnati and NKY region.” This gives AI a direct signal about your local focus, helping it recommend your business for location-based queries.
3. Ensure Accuracy: Does your site have old blog posts or outdated service pages? An AI might accidentally pull that old information. The llms.txt file acts as the single source of truth, prioritizing the information you want highlighted.
4. Future-Proof Your Website: AI is becoming deeply integrated into search engines and browsers. Having an llms.txt file is a foundational step in preparing your website for the next generation of the internet, where AI-driven summaries may be a user’s first interaction with your brand.

The Easy Way to Add llms.txt to Your Website

While you can create and upload this file manually, why would you want to? For most businesses, especially those using a platform like WordPress, the process is much simpler. Here’s the practical, non-technical way to get it done.

For WordPress Websites: Use a Plugin

Your WordPress dashboard holds the key. Instead of dealing with file managers and FTP, you can use a plugin to add these instructions in minutes.

Step 1: Check Your Existing SEO Plugin First

Before you install anything new, check the tool you already have.

Major SEO plugins like Yoast SEO, Rank Math, and All in One SEO are rapidly adding features to manage how crawlers and AI interact with your site.

• How to check: Go to your SEO plugin’s settings in your WordPress dashboard. Look for a “Tools” or “File Editor” section. You may find an option to edit your robots.txt file, and there might be a new, dedicated field for llms.txt.
• Why this is best: Using your existing plugin avoids adding unnecessary new software to your site.

Step 2: Find a Dedicated llms.txt Plugin

If your SEO plugin hasn’t added the feature yet or it isn’t satisfying all of what you need/want to put into your llms.txt, a dedicated plugin is the next best thing.

• How to find one: In your dashboard, go to Plugins > Add New.
  • We recommend: Website LLMs.txt
• What to search for: Type in “llms.txt” or “AI instructions file“.
• As this standard grows, you will see more specialized, easy-to-use plugins appear. Look for one with good reviews that has been recently updated.

What to Paste Into Your Plugin’s Settings

Once you find the right field in your plugin, the hard part is over! Now, you just need to provide the instructions. You can use our template below as a starting point—just copy, paste, and customize it for your business.
