Scanned: 2026-10-16 (Provisional: the action test and the assistant citation check still to come; the hatched part of the bar is not measured yet.)
Gerhard-Marcks-Haus is hard for agents to use.
Some AI assistants are turned away by the website of Gerhard-Marcks-Haus. It finds no menu or price list, so it answers from other sites. It finds no link to book or order online, only a phone number.

## Direct links
- Phone: +494219897520

## What to fix first
- **No ticket link on the website.** (+13 points) Only a phone number or WhatsApp, which agents cannot use yet. If you take bookings or orders through a platform, link to it from the site so an agent can find it. Add a ticket or booking page. Guide: https://directindex.org/guides/book-direct-on-your-own-website
- **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
- **Structured data is incomplete.** (+6 points) Missing: address, telephone, opening hours. Guide: https://directindex.org/guides/structured-data-restaurant
- **The server turns AI crawlers away at the door.** (+3.3 points) Live fetches as ClaudeBot (http_403) were refused while a normal browser got the page. This is usually a hosting or firewall bot list the owner never chose. Ask the host to allow these user agents. Guide: https://directindex.org/guides/blocking-ai-crawlers-without-knowing
- **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
