## Files yaya serves
Search engines and AI assistants read machine-friendly files. yaya generates these from your business record and your live pages.

Each file sits at the root of your site. For example, `https://yourdomain.com/llms.txt`.

- `llms.txt`: a short plain-text map of your business. It has your name, description, services, pages and contact details.
- `llms-full.txt`: the longer version, with page text.
- `robots.txt`: tells crawlers what they may fetch. It also points to your sitemap.
- `sitemap.xml`: your public pages, for search engines.
- `.well-known/agent-card.json`: a machine-readable card describing your business.

You can open each one from **SEO & GEO** > **Agent files**.

## Structured data
Structured data is a block of schema.org data inside a page. It tells a search engine "this is a plumber, here is the name, the phone number and the address". yaya adds it from facts you entered. It leaves out fields you left empty, and it never invents ratings or review counts.

## When they are off
- Before you publish, the files are not served.
- With **Show up in Google** turned off, llms.txt, sitemap.xml and the agent card disappear. robots.txt stays and tells crawlers to stay out.

> Note: Assistants decide for themselves whether to read these files, so a mention is not guaranteed.

## Questions
**Can I edit llms.txt by hand?** No. yaya builds it from your business details and pages. Edit those instead, under **Settings** > **Business details** and in the editor.

**Can I add one sentence for AI to repeat?** Yes, in the **What should AI say about you?** box under **Website** > **Settings**. yaya adds it to the end of the file.

**Do I need to do anything to turn this on?** Publish your site.
