## What to fix first
- **Structured data is incomplete.** (+6 points) Missing: address, telephone, opening hours. Guide: https://directindex.org/guides/structured-data-restaurant
- **Ordering through an unrecognised third party.** (+5 points) Check that the provider keeps you as the merchant of record. Guide: https://directindex.org/guides/online-ordering-without-delivery-apps

## 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.

## Already right
- **robots.txt lets AI crawlers in.** No rule blocks the key AI user agents.
- **AI crawlers get the page.** GPTBot, ClaudeBot and PerplexityBot all received a normal response.
- **Structured data present (Organization).** but without address, phone or hours
- **Menu or price list is an HTML page.** Agents can read items and prices directly.
- **Booking through opentable on your own domain.** No marketplace commission, and the guest stays yours.
- **OpenTable works with agents through its partners.** OpenTable's terms page could not be fetched on 2026-10-15; OpenTable names over 200 authorized partners, Google, Meta and OpenAI among them, as the channels through which agents book. Read 2026-10-15: https://mynews13.com/fl/orlando/business/2026/07/14/opentable-new-terms. An assistant that is not a partner may not finish the step there; a direct path on your own domain works for all of them.
