## What to fix first
- **Structured data is incomplete.** (+3 points) Missing: address, telephone. 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
- **No llms.txt.** (no points, but worth doing) Optional for now and cheap to add. It's a short text file that describes the business for language models. Guide: https://directindex.org/guides/llms-txt-for-a-business

## 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.

## 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 (Restaurant).** opening hours
- **Booking through resdiary on your own domain.** There's no marketplace commission, and the customer stays yours.
- **ResDiary works with agents through its partners.** ResDiary's consumer terms bar any robot, spider, scraper or other automatic means of access except as expressly authorised by ResDiary; Google names ResDiary as an AI Mode booking partner. Terms read on 2026-10-15: https://www.resdiary.com/old/Terms. An assistant that isn't a partner may not be able to finish there. A direct path on your own domain works for all of them.
