# Dr. Katarina + Wolf-Dieter Preugschat: Agent-Direct Score F (38%)

Site: https://rb17-zahnarzt-rahlstedt.de/
Report: https://directindex.org/r/rb17-zahnarzt-rahlstedt.de
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.)
Dr. Katarina + Wolf-Dieter Preugschat is largely invisible to agents.
Some AI assistants are turned away by the website of Dr. Katarina + Wolf-Dieter Preugschat. 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: +4940 661101

## What to fix first
- **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 online booking 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 an online appointment page. Guide: https://directindex.org/guides/book-direct-on-your-own-website
- **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.** (+3.3 points) Live fetches as PerplexityBot (http_503) 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

## 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.
