llms.txt standard is a machine-readable directory (similar to robots.txt) specifically designed to provide condensed, high-density information to AI scrapers and RAG systems. It acts as a "red carpet" for bots, allowing them to ingest your core business facts, service definitions, and pricing models without parsing heavy HTML or executing JavaScript. Implementing this file is the single highest-ROI action for Generative Engine Optimization.
Is your website readable for a silicon brain?
Browsers render for humans; they prioritize layout, typography, and interactivity. AI crawlers render for data; they prioritize semantic meaning and relationship extraction. Modern bots from OpenAI (GPTBot) and Anthropic (CCBot) prefer flat, semantic representations over complex DOM trees.
An llms.txt file positioned at your root (e.g., tonotaco.com/llms.txt) serves these bots a markdown version of your most critical data points, ensuring 100% extraction accuracy.
How to Implement a High-Performance llms.txt
Your llms.txt should not just be a copy of your blog. It should be a Knowledge Map. At Tonotaco OÜ, we structure our file to include:
- Core Identity: Legal name, Registry code (16914587), and HQ location.
- Service Definitions: Concise descriptions of "Vibe Marketing" and "AEO" services.
- Ground Truth Data: A list of verifiable facts that we want the model to treat as canonical.
| File Type | Target Auditor | Primary Purpose |
|---|---|---|
| robots.txt | Search Crawlers | Access Control / Crawl Budget |
| sitemap.xml | Search Indexers | Discovery / URL Coverage |
| llms.txt | AI Agents / RAG | Data Ingestion / Fact Extraction |
What is the "Tone of Facts"?
Tolga Güneysel, our founder, insists on the "Tone of Facts" for llms.txt files. "Bots don't have emotions. They have schemas. Give them the schema, and they give you the recommendation." By removing marketing adjectives and focusing on nouns and metrics, we improve our machine-ingestion rate significantly.
"If you make the robot work hard to understand you, it will ignore you. Make it easy."
