# アーク歯科・矯正歯科: Agent-Direct Score B (75.4%) Site: http://www.arc-d.com Report: https://directindex.org/r/arc-d.com Scanned: 2026-10-22 (Provisional, with the action test and the assistant citation check still to come. The hatched part of the bar isn't measured yet.) アーク歯科・矯正歯科 is mostly ready for agents. An AI assistant can open アーク歯科・矯正歯科'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 on the site. ## Direct links - Book directly: https://arc-d.com/reservation (on the business's own site) - Phone: 03-3760-9191 - Address: 鷹番2-19-3, 152-0004, 目黒区 ## Nearby, also direct Places near アーク歯科・矯正歯科 that take a booking or an order on their own website, with no marketplace in between. - 桜ウィメンズクリニック (140 m): https://directindex.org/r/sakura-w.jp - 学芸大耳鼻咽喉科 (150 m): https://directindex.org/r/gd-ent.jp - さくらんぼ皮膚科 (170 m): https://directindex.org/r/sakuranbo-d.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.** (+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 - **The phone number on the site doesn't match the open map data.** The site shows 0120418691, but OpenStreetMap or Overture Maps lists 03-3760-9191. 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. ## 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. ``` # アーク歯科・矯正歯科 > organization in 鷹番2-19-3, 152-0004, 目黒区, Tokyo dentists, clinics and vets.
