# Dr. Christa Horn Fachärztin für Zahn-, Mund- und Kieferheilkunde: Agent-Direct Score D (45.1%) Site: http://hoertnagl.at Report: https://directindex.org/r/hoertnagl.at Scanned: 2026-10-18 (Provisional, with the action test and the assistant citation check still to come. The hatched part of the bar isn't measured yet.) Dr. Christa Horn Fachärztin für Zahn-, Mund- und Kieferheilkunde is hard for agents to use. Some AI assistants are turned away by Dr. Christa Horn Fachärztin für Zahn-, Mund- und Kieferheilkunde's website. It can't find a menu or price list, so it answers from other sites. It finds a phone number, but no link to book or order online. ## Direct links - Phone: +43316715359 ## What to fix first - Prices: 5 prices on the site, the middle one €11.50 ## 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 Graz, 5.0% of comparable sites declare one. - **5 prices on the landing page, the middle one €11.50.** - **No online booking link on the website.** (+13 points) There's only a phone number or WhatsApp, and agents can't use those yet. If you take bookings or orders through a platform, link to it from the site so agents can find it. Add an online appointment page. Guide: https://directindex.org/guides/book-direct-on-your-own-website - **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 ## Fix kit: What to paste Structured data (JSON-LD).
