# Cmd Dr. Peter Grewe: Agent-Direct Score D (50.3%) Site: http://www.dr-peter-grewe.de/ Report: https://directindex.org/r/dr-peter-grewe.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.) Cmd Dr. Peter Grewe is hard for agents to use. Some AI assistants are turned away by Cmd Dr. Peter Grewe'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/zahnmedizin/koeln/peter-grewe?utm_campaign=website-button&utm_source=online-booking&utm_medium=referral (through doctolib acting for the business) - Phone: 492212576402 - Address: Schildergasse 120, 50667, Cologne ## Nearby, also direct Places near Cmd Dr. Peter Grewe that take a booking or an order on their own website, with no marketplace in between. - Handzentrum Köln (30 m): https://directindex.org/r/handzentrum.koeln - Dr. Yavuz Şahin (30 m): https://directindex.org/r/dr-sahin.de - Androloge & Urologe Köln - Dr. Dr. med.

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 - **The server turns AI crawlers away at the door.** (+3.3 points) Requests as PerplexityBot (http_503) 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 - **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) - **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. ```html ``` llms.txt. Save as /llms.txt at the root of the site. ``` # Cmd Dr. Peter Grewe > local business in Schildergasse 120, 50667, Cologne, Cologne dentists, clinics and vets.
