## What to fix first
- **No booking or ordering path at all.** (+13 points) Only a phone number or WhatsApp. Agents cannot act on those yet. Add a booking or ordering page. Guide: https://directindex.org/guides/book-direct-on-your-own-website
- **Structured data is incomplete.** (+6 points) Missing: address, telephone, opening hours. Guide: https://directindex.org/guides/structured-data-restaurant
- **No working HTTPS.** (+3 points) The page is only served over plain http. Agents and browsers downrank or refuse it.
- **Menu or price list is a PDF.** (+3 points) Most agents skip PDFs or read them badly. Publish it as HTML, keep the PDF as a download. Guide: https://directindex.org/guides/menu-pdf-ai
- **No llms.txt.** (no points, still worth doing) Optional today, cheap to add: a short text file describing the business for language models. Guide: https://directindex.org/guides/llms-txt-for-a-business

## Fix kit: What to paste

Structured data (JSON-LD). One block in the page's head, or in the builder's custom-code slot. Replace anything that is wrong.
