## What to fix first
- **Booking through an unrecognised third party.** (+9 points) Check that the provider keeps your business as the seller of record. Guide: https://directindex.org/guides/book-direct-on-your-own-website
- **Menu or price list is a PDF.** (+3 points) Most agents skip PDFs or read them badly. Publish it as an HTML page and keep the PDF as a download. Guide: https://directindex.org/guides/menu-pdf-ai
- **The phone number on the site doesn't match the open map data.** The site shows +4922376948890, but OpenStreetMap or Overture Maps lists 04921 1393698. An assistant that sees two numbers can't tell which one to trust. Fix whichever is wrong, on the site or in the map data at openstreetmap.org.

## Already right
- **robots.txt lets AI crawlers in.** No rule blocks the main AI user agents.
- **AI crawlers get the page.** GPTBot, ClaudeBot and PerplexityBot all got a normal response.
- **Structured data found (FoodEstablishment).** address, phone, opening hours
