## What to fix first
- **Structured data is incomplete.** (+3 points) Missing: opening hours. Guide: https://directindex.org/guides/structured-data-restaurant
- **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.

## About

- Website: https://www.halfshellseattle.com/
- This file follows llms.txt (https://llmstxt.org): a short plain-text description for language models.
```

## 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 (FoodEstablishment).** address, phone
- **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.
- **Ordering through bentobox on your own domain.** No marketplace commission, and the guest stays yours.
- **OpenTable lets agents act only 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 cannot finish the step there; a direct path on your own domain works for all of them.
