AI instruments are all over the place — from chatbots that reply buyer inquiries to language fashions that summarize every thing from documentation to authorized textual content. However in the event you’ve ever requested a mannequin like ChatGPT to elucidate your website, your product, or your API, the outcomes may not really feel fairly proper. In reality, generally they’re approach off. And no, that’s not your fault.
The disconnect between web sites and LLMs
Giant language fashions (LLMs) like ChatGPT, Claude, or Gemini are skilled to grasp a variety of content material. However after they attempt to interpret your web site at runtime, that’s, when somebody is actively asking them a query, they run into just a few core issues:
- HTML is noisy. Navigation bars, cookie banners, modal popups, and analytics scripts muddle the web page.
- Context home windows are restricted. Most web sites are too massive for an LLM to course of unexpectedly.
- Necessary particulars are unfold throughout a number of pages or hidden in tables, code blocks, or feedback.
- Markdown docs might exist, however the mannequin usually can’t find them, and even know they exist.
So, while you ask an AI device to “clarify what this firm does” or “summarize this library API”, it usually will get caught. It both skips key context or grabs the mistaken alerts from cluttered markup.
It’s not unhealthy intent; it’s a design limitation.
Why it’s not your search engine marketing’s fault, both
You’ve most likely invested effort and time into search engine marketing. Perhaps your robots.txt and sitemap.xml are in place. You’ve received meta tags, structured information, and clear inside hyperlinks. Good, however LLMs don’t at all times work like Google.
Conventional search engine marketing helps your website get discovered. Nevertheless, it doesn’t assure that AI instruments will perceive what a human consumer would. That’s the place a brand new proposal is available in.
Meet llms.txt: A easy approach to assist AI perceive your website
A rising variety of builders and AI researchers are adopting a light-weight, human-readable customary referred to as llms.txt.
What’s llms.txt?

Is it broadly supported? Not but
Proper now, no main LLM supplier formally helps llms.txt. Instruments like GPTBot (OpenAI), Claude (Anthropic), and Google’s AI crawlers don’t reference or observe it as a part of their crawling conduct. Some corporations like Anthropic publish llms.txt information themselves, however there’s no proof that any crawler is actively utilizing them in retrieval or coaching.
Nonetheless, it’s a low-effort, no-risk addition that helps put together your website for a future the place structured LLM entry turns into extra standardized. And LLM-facing instruments, and even your individual AI brokers, could make use of it right this moment.

Sitemaps assist crawlers discover every thing. llms.txt tells LLMs what to focus on.
