We have spent the last two decades optimizing the DOM for Google's crawlers. We obsess over semantic HTML, hydration, and Core Web Vitals. But in 2026, the game has changed. We aren't just building for browsers anymore; we are building for Agents.
Welcome to the era of GEO (Generative Engine Optimization).
The Problem: HTML is "Expensive"
When an AI agent (like Gemini, ChatGPT, or a custom RAG pipeline) crawls your site, it isn't looking for visual layout. It’s looking for context.
Standard websites are heavy. Parsing a modern React app to extract a simple value proposition wastes tokens. If your site structure is confusing, AI models will hallucinate your services or, worse, skip you entirely to save compute costs. A low GEO score means you are effectively invisible to the "new internet."
The Solution: The llms.txt Standard
Just as robots.txt tells crawlers what they can access, llms.txt tells AI agents what matters.
This is a standardized Markdown file located at the root of your domain. It strips away the UI/UX fluff and presents your site's logic in raw, token-efficient text.
Why it matters:
Token Efficiency: Without it, AI agents waste up to 400% more tokens traversing your DOM.
Context Window: It ensures your core value prop fits within the context window of smaller, faster models.
Accuracy: It prevents hallucination by providing a source of truth.
How to Implement It
You don't need a data scientist to fix this. You just need to refactor your content for machines.
Audit your current visibility: See how an LLM currently parses your homepage.
Create the file: Generate a structured Markdown summary of your documentation and pricing.
Deploy: Place it at yourdomain.com/llms.txt.
I built Refactor.Tools to automate this process. It runs a GEO audit to show you exactly how AI sees your site (scoring readability and token efficiency) and helps you generate a compliant llms.txt instantly.
The future of the web is headless and agent-driven. Don't let your site get left behind.
