llms.txt – The New Visibility Standard in the AEO Era
Search Generative Experience and AI bots are changing how customers discover your offer. Instead of relying on crawler luck, you can provide data in the format they understand best. Here is what's changing and what you can do better.
What's changing right now
The llms.txt standard is a text file placed in the root directory that aggregates your site's key information for LLMs. It responds to the rise of GEO (Generative Engine Optimization), where AI values clean text and context over HTML tags or complex visual layouts.
What you can do better
Concretely, starting today
- Forget manual entry; use your sitemap (sitemap.xml) to automatically aggregate links for the llms.txt file.
- Focus on Markdown format – it is the native language for most AI models, making it easier for them to grasp information hierarchy.
- Include condensed FAQ answers in the file so bots can provide ready-made solutions to your customers.
- Regularly update the file with every offer change to prevent AI from hallucinating about your services or pricing.
Proof from our work
On dtl.pl our llms.txt is not a hand-written document — it is generated from the same page registry as the XML sitemap, so every new article or tool appears in it automatically, with nothing to remember. You can see the result at dtl.pl/llms.txt: models get a company description, key facts and a grouped list of pages with summaries. We implement the same mechanism for clients and measure the outcome with our own visibility checker.
Frequently asked questions
Does Google take llms.txt into account?
Currently, it's a standard supported mainly by LLM developers and tools like Perplexity, but it directly impacts AEO, which is becoming a key element of the search engine ecosystem.
Where should this file be located?
The file should be accessible at yourdomain.com/llms.txt, similar to a robots.txt file, so AI crawlers can easily find it.
