What is llms.txt and should a dealership website have one?
A plain-text file at the root of a site that points language models at its most useful pages, in the spirit of robots.txt but for retrieval rather than crawling. It is a convention, not a standard, and no system is obliged to read it. It costs almost nothing to publish and it does not substitute for the pages themselves being clear and current.

It costs almost nothing to publish and it does not substitute for the pages themselves being clear and current. It offers a curated map, the pages that best represent the site, rather than leaving a system to infer structure from navigation.
For a large reference site that is useful; for a five-page brochure site it changes little. Publishing the file does not cause a model to prefer the site.

What it is for
It offers a curated map, the pages that best represent the site, rather than leaving a system to infer structure from navigation. For a large reference site that is useful; for a five-page brochure site it changes little.
It is not a ranking mechanism
Publishing the file does not cause a model to prefer the site. Treat it as making existing quality easier to find, not as an optimisation in itself.
Keep it accurate
A file listing URLs that have moved or no longer exist is worse than none. If the site's origin changes, the file has to change with it: a static file cannot read the site's configuration on its own.
The page still has to be good
No file compensates for content that does not resolve an entity, state a scope or carry a date.
What a good file contains
A short description of the site, then a list of the most useful pages with one line on each, grouped by topic. Use full URLs that resolve to the live pages, and keep the list to pages you would want quoted.
For a dealership that might mean the about page, service information, financing and trade policies and key model pages. Avoid listing every page; the file is a curated guide.
Deciding whether to publish one
The cost is small, the benefit uncertain. If your site already has clear pages, a consistent structure and accurate facts, a file adds a convenient index.
If the site is thin or inconsistent, fix that first. Whatever you decide, do not expect a change in rankings, and do not pay a vendor a large fee for one.
Maintaining the file
Treat it as part of the site, not a one-time task. Generate it from the same source as the sitemap when possible, check it whenever pages move or are removed, and review it each quarter.
Confirm that it is served at the site root, returns a plain text response and lists the canonical domain. A stale file undermines trust in the rest of the site.
Questions to ask before paying for one
What will the file contain and who maintains it? Is it generated from the site or written by hand?
How will it be updated when pages change? What is the cost and what is the expected benefit?
A simple file can be created by a competent web developer in an hour, and an expensive package is rarely justified.
What to verify
Publish a curated map of the pages that best represent the site
Do not expect it to influence ranking on its own
Regenerate it whenever the site origin or URLs change
Fix the underlying pages first
