**Probably not—most websites don’t need an `llms.txt` file.**

It’s an optional Markdown file that gives AI tools a short introduction to your site and links to useful content. It remains a community proposal. [The llms.txt proposal](https://llmstxt.org/)

- **For Google rankings or AI search visibility:** you don’t need it. Google explicitly says Search—including its generative AI features—ignores it, so adding one neither helps nor harms your rankings. [Google’s guidance](https://developers.google.com/search/docs/fundamentals/ai-optimization-guide)
- **For developer documentation or a specific AI tool that reads it:** it can be useful as a curated guide to your content. It doesn’t replace `robots.txt` or your sitemap. [The proposal’s intended uses](https://llmstxt.org/)

For a typical business website, I’d prioritise useful, accurate content, accessible pages and up-to-date business details. Consider `llms.txt` when you have a specific use for it; don’t treat it as a required SEO upgrade.
