Nothing to fix
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) address, phone, opening hours
- Menu or price list is an HTML page Agents can read the items and prices.
- Booking through opentable on your own domain There's no marketplace commission, and the customer 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. Terms read on 2026-10-15: https://mynews13.com/fl/orlando/business/2026/07/14/opentable-new-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.
