Report: https://directindex.org/r/stammhaus-restaurant.at
Scanned: 2026-10-14 (Provisional: the action test and the assistant citation check still to come; the hatched part of the bar is not measured yet.)
Stammhaus is partly visible to agents.

## Direct links
- Book directly: https://widget.thefork.com/1dbc984a-e1b9-4d09-bcf9-ccf8dbde9b5c (through thefork acting for the business)
- Menu: http://www.stammhaus-restaurant.at/

## What to fix first
- **No structured data for the business.** (+15 points) Add schema.org JSON-LD for the business (Restaurant, LocalBusiness or the closest type, with name, address, telephone and openingHoursSpecification, plus servesCuisine and acceptsReservations). It is the one block every assistant reads first; the fix kit below has it filled in. 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.
- **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.

- Website: http://www.stammhaus-restaurant.at
- 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.
- **Menu or price list with prices on the page.** Agents can read items and prices directly.
- **Booking through thefork on your own domain.** No marketplace commission, and the guest stays yours.
- **TheFork works with agents through its partners.** TheFork's terms page could not be fetched on 2026-10-15; TheFork integrated OpenAI's Operator agent for UK bookings in February 2025 and is a named Google AI Mode booking partner. Read 2026-10-15: https://itbrief.co.uk/story/thefork-integrates-openai-s-operator-for-uk-bookings. 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.
