Scanned: 2026-10-14 (provisional: the action test and the assistant citation check pending)
Zahn 33 is hard for agents to use.

## Direct links
- Book: https://partners.doctolib.de/zahnarztpraxis/berlin/kurganova/booking/places (through doctolib acting for the business)
- Phone: +4930439719030

## What to fix first, by points
- **No structured data for the business.** (+14 points) Add schema.org JSON-LD for the business (Dentist, MedicalClinic, Physiotherapy or the closest type, with name, address, telephone and openingHoursSpecification). 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 list of services and prices found.** (+7 points) Agents answer 'what do they treat and what does it cost' from directories instead. Add a page with services and prices as text and link it from the homepage. Guide: https://directindex.org/guides/menu-pdf-ai
- **The server turns AI crawlers away at the door.** (+6.7 points) Live fetches as GPTBot (http_403), 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
