Site: https://www.opsolder.nl/
Report: https://directindex.org/r/opsolder.nl
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.)
Ons' Lieve Heer op Solder is mostly ready for agents.

## Direct links
- Book directly: https://opsolder.nl/tickets-en-prijzen/ (on the business's own site)
- Phone: +31 20 624 6604

## What to fix first
- **Structured data is incomplete.** (+7 points) Missing: address, telephone, opening hours. Guide: https://directindex.org/guides/structured-data-restaurant
- **No tickets and prices found.** (+7 points) Agents answer 'what does it cost and when' from marketplaces instead. Add a page with tickets, times and prices as text and link it from the homepage. Guide: https://directindex.org/guides/menu-pdf-ai
- **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.
