An llms.txt file is an optional Markdown summary intended to help tools understand a website. It is not a Google indexing requirement, a replacement for your pages or a reliable way to force an AI answer to change.
Google's generative AI optimization guide says Google Search ignores llms.txt. Maintaining one neither improves nor harms Google rankings. If someone is selling it as the main reason your agency will appear in AI answers, ask what else the work includes.
What belongs in the file
Include the business name, a short factual description, links to important pages and clear descriptions of what each page covers. If you include prices or terms, generate them from the same source as the visible website.
For an insurance agency, useful links might include office locations, coverage information, contact details and an explanation of how to request a quote. Avoid including private customer information or internal instructions.
A minimal illustrative structure:
# Example Agency
> An insurance agency serving the areas described on its office pages.
## Important pages
- [Offices](https://example.com/offices): Addresses, hours and contact details.
- [Services](https://example.com/services): Coverage information.
- [Contact](https://example.com/contact): How to request assistance.
Replace the example links with the agency’s maintained public pages.
Keep current facts separate from historical writing
An archive may include old prices, retired services or vendor comparisons. Republishing all of it into a larger text feed gives those statements another place to appear. Correct the source article and show a meaningful update date when its content changes.
Use the website’s current business information when maintaining the summary. Update links and service descriptions when the corresponding pages change.
What this file cannot do
It cannot require Google to index a page, override robots directives, prove authorship or make unsupported claims trustworthy.
Tools differ in which sources they fetch and how they quote them. Check actual answers and their cited URLs, record the date and correct inaccurate source material. A changed answer in one test is not a market-wide visibility measurement.
Priorities before adding another file
Make the pages accessible, link important content through ordinary HTML navigation, use accurate titles and canonical URLs, and keep business facts consistent. Explain real work and cite primary sources for changing technical claims.
For the agency website itself, website design and development should focus on useful visitor tasks first. An optional summary is maintenance work, not an alternative to a clear website.
