WHITO GLOSSARY · MEASURED DEFINITIONS
A plain-text file telling AI systems what a site offers and where its key pages are. Adoption is tiny: 1 site in 120 UK independent business websites audited had a hand-written llms.txt.
The number: AI Readiness of UK Business Websites.
What it means in practice
llms.txt is cheap, quick and almost nobody has one. That is the entire argument: a small readable file against a field that has not moved.
Write it by hand: what the business does, where the key pages are, what your research or proof pages contain. Ten minutes, done once, read by machines forever.
Whito stage: Build. Buy this once the foundations are set, not before.
The numbers to hold onto
- 1 site in 120 UK independent business websites audited had a hand-written llms.txt. AI Readiness of UK Business Websites.
- 92% of the same sites had no AI crawler policy of any kind. AI Readiness of UK Business Websites.
