# Mathias Sperl: Agent-Direct Score D (49.2%) Site: http://www.zahnarzt-sperl.de Report: https://directindex.org/r/zahnarzt-sperl.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.) Mathias Sperl is hard for agents to use. An AI assistant can open Mathias Sperl'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/nuernberg/mathias-sperl?utm_source=google-maps&utm_campaign=google-maps (through doctolib acting for the business) - Address: Veillodterstraße 35 90409 Nürnberg - Hours, from OpenStreetMap · Overture Maps: Mon 08:00–12:00, 15:00–18:00; Tue 14:00–20:00; Wed 08:00–13:00; Thu 08:00–12:00, 15:00–18:00; Fri 08:00–12:00; Sat–Sun closed - Open after 19:00 on a weekday ## Nearby, also direct Places near Mathias Sperl that take a booking or an order on their own website, with no marketplace in between. - Zahnarzt Dr. Dennerlein (160 m): https://directindex.org/r/zahnarzt-dennerlein.de ## What to fix first - **No structured data for the business.** (+15 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 working HTTPS.** (+3 points) The page is only served over plain http. Browsers and agents rank it lower or refuse it. - **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 Nuremberg, 3.0% 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. ```html ``` llms.txt. Save as /llms.txt at the root of the site. ``` # Mathias Sperl > dentist in Veillodterstraße 35 90409 Nürnberg, Nuremberg dentists, clinics and vets. ## Book or order directly - Book: https://www.doctolib.de/zahnmedizin/nuernberg/mathias-sperl?utm_source=google-maps&utm_campaign=google-maps (through doctolib acting for the business) ## Opening hours Mo, Th 08:00-12:00, 15:00-18:00; Tu 14:00-20:00; We 08:00-13:00; Fr 08:00-12:00 ## About - Website: http://www.zahnarzt-sperl.de - This file follows llms.txt (https://llmstxt.org): a short plain-text description for language models. ``` ## 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. - **Appointments through doctolib on your own domain.** There's no marketplace commission, and the customer stays yours. ## Where it stands 410 of 1106 in Nuremberg dentists, clinics and vets.
