# Dr. Hornung: Agent-Direct Score C (60%)

Site: https://www.aerzte-hornung.de
Report: https://directindex.org/r/zahnarzt-essen-bergerhausen.de
Scanned: 2026-10-16 (Provisional, with the assistant citation check still to come. The hatched part of the bar isn't measured yet.)
Dr. Hornung is partly visible to agents.
An AI assistant can open Dr. Hornung's website. It can't find a menu or price list, so it answers from other sites. It finds a way to book or order directly on the site.

## Direct links
- Book directly: https://www.zahnarzt-essen-bergerhausen.de/terminvereinbarung/ (on the business's own site)
- Phone: +492018119533
- Address: Wallotstraße 4 45136 Essen

## Nearby, also direct
Places near Dr. Hornung that take a booking or an order on their own website, with no marketplace in between.
- Brandt-Mainz Dr. med., Moka Prof. Dr. med., Röhlen Dr. Dr. med., Uhrhan K. (110 m): https://directindex.org/r/nukmed.de

## 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). Every assistant reads this block first, and 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 that lists services and prices as text, and link to it from the homepage. Guide: https://directindex.org/guides/menu-pdf-ai
- **No llms.txt.** (no points, but worth doing) Optional for now and cheap to add. It's a short text file that describes the business for language models. Guide: https://directindex.org/guides/llms-txt-for-a-business

## What the site tells visitors (Measured, not scored)
- **The footer says © 2020.** Visitors and assistants may read that year as the last time anyone looked after the site. In Essen, 71% of comparable sites that show a year say 2025 or later.
- **No English version declared.** Visitors from abroad, and assistants answering in English, read the page as it is. In Essen, 4.0% of comparable sites declare one.

## Fix kit: What to paste

Structured data (JSON-LD). Paste it as one block in the page's head, or in the builder's custom code box. Change anything that's wrong.
