Site: http://www.zahn-3.de/
Report: https://directindex.org/r/zahn-3.de
Scanned: 2026-10-20 (Provisional, with the action test and the assistant citation check still to come. The hatched part of the bar isn't measured yet.)
ZAHN³ Düsseldorf MVZ is partly visible to agents.
Some AI assistants are turned away by ZAHN³ Düsseldorf MVZ'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, through Doctolib.

## What to fix first
- **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
- **The server turns AI crawlers away at the door.** (+6.7 points) Requests as GPTBot (http_403), ClaudeBot (http_403) were refused, but a normal browser got the page. That's usually a bot list at the host or in a firewall that the owner never chose. Ask the host to allow these user agents. Guide: https://directindex.org/guides/blocking-ai-crawlers-without-knowing
- **Structured data is incomplete.** (+6 points) Missing: address, telephone, opening hours. Guide: https://directindex.org/guides/structured-data-restaurant

## What the site tells visitors (Measured, not scored)
- **No English version declared.** Visitors from abroad, and assistants answering in English, read the page as it is. In Düsseldorf, 9.2% 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.

## Already right
- **robots.txt lets AI crawlers in.** No rule blocks the main AI user agents.
- **Structured data found (Organization).** no address, phone or hours in it
- **Appointments through doctolib on your own domain.** There's no marketplace commission, and the customer stays yours.
- **Ordering on your own site.** Agents can order without going through a marketplace.
