## What to fix first
- **The site turns away every visitor that isn't a browser, AI agents included.** (+25 points) A plain fetch was refused (cloudflare_challenge). Only a real browser got the page. Every AI crawler and agent gets turned away the same way, so Reachable scores 0 and the rest is measured on the page as the browser rendered it. Ask the host to let the AI user agents through. Guide: https://directindex.org/guides/blocking-ai-crawlers-without-knowing
- **Structured data is incomplete.** (+5 points) Missing: telephone, opening hours. Guide: https://directindex.org/guides/structured-data-restaurant
- **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

## What the site tells visitors (Measured, not scored)
- **No English version declared.** Visitors from abroad, and assistants answering in English, read the page as it is. In Lausanne, 18% of comparable sites declare one.

## Fix kit: What to paste

Structured data (JSON-LD). Paste it as one block in the page's head, or in the builder's custom code box. Change anything that's wrong.
