Is llms.txt an official standard?

No. It is a convention rather than a specification any vendor has committed to reading. We treat it as a low-cost way to state public facts in one machine-readable place, not as a ranking mechanism.

Do I need both files?

Not necessarily. The short index is worth having on its own. The expanded file only earns its place when there is genuine detail to record — founders, service scope, measurement context — that the index cannot carry.

What makes an implementation fail?

Vagueness and drift. A file written in marketing language gives a crawler nothing to work with, and a file that still lists last year's services actively contradicts the site it points at.

How does this relate to robots.txt and sitemap.xml?

They answer different questions. robots.txt states who may fetch, sitemap.xml states what exists, and llms.txt states what matters and why. None of them substitutes for another.

llms.txt

llms.txt Implementation for AI Search Visibility

A plain-text file that states who a company is, what it sells and which pages matter — without the navigation, scripts and markup that surround the same facts in HTML. Both of ours are live on this domain.

Excerpt from the live file — /llms.txt

What the file does

States the canonical domain and company name in one machine-readable place
Names the pages a company considers most important
Removes the navigation, scripts and markup that surround the same facts in HTML
Gives a stable URL that can be re-read whenever the site changes

What it does not guarantee

It is not a ranking signal and no vendor promises to read it
It cannot make a claim true that the website does not support
It does not replace robots.txt, sitemap.xml or structured data
A published file with stale facts is worse than no file at all

Two files

Where the short and the long file differ

They are not one document at two lengths. They answer different questions and go stale for different reasons.

Purpose: llms.txt — a short index of what matters; llms-full.txt — the expanded profile behind it
Content: Company summary, canonical domain, services, priority URLs; Founder context, service detail, public limitations and maintenance context
Maintenance: Changes when the page inventory changes; Changes when the business or the people behind it change

Lifecycle

How the file gets written and kept alive

A high-level view of the sequence. The file only stays useful for as long as it agrees with the website it describes.

Review public company information
We work from what the website, profiles and documentation already state — the file records facts, it does not invent them.
Prepare the public file
Company summary, canonical domain, services and priority URLs are written as plain text with a predictable shape.
Validate accessibility and consistency
The file has to be reachable as plain text and agree with the pages it points to, or it becomes another contradictory source.
Maintain when the website changes
New services, renamed pages and moved URLs make the file stale, so ownership of updates is agreed up front.

What you get

A file you can defend, not just publish

The deliverable is the published file plus the reasoning behind what went in and what stayed out. Anything the website cannot already support does not belong in it.

The published file on your canonical domain
A page map showing which URLs were prioritised and why
Notes on claims the site could not support
An agreed owner and trigger for updates
