Scanned: 2026-10-17 (Provisional: the action test and the assistant citation check still to come; the hatched part of the bar is not measured yet.)
Hno-praxis Prof. Dr. Gero Strauss is hard for agents to use.
An AI assistant can open the website of Hno-praxis Prof. Dr. Gero Strauss. It finds no menu or price list, so it answers from other sites. It finds a way to book or order directly, through Doctolib.

## Direct links
- Book directly: https://www.doctolib.de/facharzt-fur-hno/berlin/gero-strauss-berlin (through doctolib acting for the business)
- Phone: 4915207597442

## What to fix first
- Languages: Arabic, German, English, Spanish, French, Italian, Russian, Turkish
- WhatsApp: a link on the site

- **No structured data for the business.** (+15 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

## 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.
