What is llms.txt?
llms.txt is a text file placed at yoursite.com/llms.txt that lists your key pages in tidy, AI-friendly text, so a bot can skip the digging. Here is the honest part: it is a proposal some sites have adopted, not an official standard, and it is not something every AI tool actually reads.
In plain English
It is like leaving a table of contents on your porch in case a visitor wants a shortcut. Some visitors will glance at it. Most will just walk through the house the normal way regardless.
What to actually do
Get robots.txt right first
Make sure your actual crawling rules are not blocking AI bots.
Write clear, readable pages
Plain, well-organized pages matter far more than any extra file.
Add llms.txt only if you like it
Treat it as a nice-to-have, not a fix for a site that is otherwise hard to read.
Worth remembering
Google's own 2026 guide says it plainly: you do not need AI text files like this, and Google Search does not use them.
So do not chase it as a shortcut. The fundamentals, a clean robots.txt and genuinely clear pages, are what actually move the needle for how AI and search treat your site.
What to do about it
Focus your time on robots.txt and clear, readable pages before you worry about llms.txt at all. Want help prioritizing what actually matters for your site? Get a free website audit.
