Does my small business need an llms.txt file?

An honest answer about llms.txt for small businesses: what it's meant to do, what the current evidence says, and where your effort is better spent.

Quick answer

llms.txt is a proposed convention — a plain-text file at your domain root summarising your site for AI systems. It's cheap to add and harmless, but adoption by major AI providers is not established, so treat it as a low-cost hedge rather than a fix. If AI assistants can't describe your business, the cause is almost always missing crawlable content, not a missing llms.txt.

Step-by-step

Understand what it's proposing to solve

The idea is that AI systems reading your site face a lot of navigation, scripts and boilerplate. An llms.txt file at your domain root offers a clean, structured summary — what the site is, what the key pages are — so a machine doesn't have to infer it. Sensible in principle.

Be realistic about whether it currently works

It's a proposed convention rather than an adopted standard, and support from major AI providers isn't established. Anyone telling you it's essential is ahead of the evidence. It costs almost nothing to add, which is the honest argument for it — not that it's proven.

Fix the actual problem first

If AI assistants can't describe your business, it's overwhelmingly likely that there isn't enough clear, crawlable text about your services, location and prices — or nothing independent corroborating it. An llms.txt file summarising a thin site just summarises a thin site.

Add it if you want, and keep it short

A plain-text file at yourdomain.com/llms.txt with your business name, what you do, where you operate, and links to your most important pages. Keep it current — a stale file describing services you dropped is worse than none. If you're on a builder that doesn't allow root files, skip it without concern.

Spend the remaining effort on what's proven

Specific text on real pages, a complete Google Business Profile, consistent details across directories, and mentions somewhere independent. Those demonstrably affect whether AI assistants can talk about you. Do them first, then add llms.txt as a cheap extra.

Tips & best practices

▸Cheap and harmless is the honest case for llms.txt — not that it's proven to work.
▸A stale llms.txt is worse than none; update it when your services change.
▸It cannot compensate for a site with no substantive text on it.
▸Don't pay anyone a meaningful sum to add one; it's a short text file.

Common questions

What is llms.txt?

A proposed convention: a plain-text file at your domain root that gives AI systems a clean summary of what your site is and which pages matter, rather than making them infer it from navigation and boilerplate.

Does llms.txt actually do anything?

It's not an adopted standard and support from major AI providers isn't established, so there's no reliable evidence it changes outcomes today. It's cheap and harmless to add, which is the honest reason to bother — not that it's proven.

Should my small business add one?

If it takes ten minutes and your platform allows root files, sure. But add it after you've published clear text about your services, completed your Google Business Profile, and got your details consistent across directories — those are the things that demonstrably matter.

What should be in an llms.txt file?

Your business name, what you do, where you operate, and links to your most important pages, in plain text. Short and current beats long and stale.
