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.)
Zahnarzt Cologne is partly visible to agents.
Some AI assistants are turned away by Zahnarzt Cologne'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.

## Direct links
- Book directly: https://www.doctolib.de/gemeinschaftspraxis/koeln/zahnarzt-cologne (through doctolib acting for the business)

## 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
- **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 © 2024.** Visitors and assistants may read that year as the last time anyone looked after the site. In Cologne, 70% 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 Cologne, 5.5% 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.
