Site: http://www.hno-kalk.de/
Report: https://directindex.org/r/hno-kalk.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.)
Hno Kalk is mostly ready for agents.
An AI assistant can open Hno Kalk'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/hno-kalk (through doctolib acting for the business)
- Phone: 49221852233
- Address: Johann-Classen-Straße 68, 51103, Cologne

- Dr. Schneider · Köln (460 m): https://directindex.org/r/dr-schneider-koeln.com

## 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
- **Structured data is incomplete.** (+3 points) Missing: opening hours. Guide: https://directindex.org/guides/structured-data-restaurant
- **The phone number on the site doesn't match the open map data.** The site shows 01607469995, but OpenStreetMap or Overture Maps lists 49221852233. An assistant that sees two numbers can't tell which one to trust. Fix whichever is wrong, on the site or in the map data at openstreetmap.org.

## 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 Cologne, 5.0% 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.

## Already right
- **robots.txt lets AI crawlers in.** No rule blocks the main AI user agents.
- **AI crawlers get the page.** GPTBot, ClaudeBot and PerplexityBot all got a normal response.
- **Structured data found (LocalBusiness).** address, phone
- **Appointments through doctolib on your own domain.** There's no marketplace commission, and the customer stays yours.
