# Vietnam: Agent-Direct Score D (43.5%) Site: https://restaurant-vietnam.ch/ Report: https://directindex.org/r/restaurant-vietnam.ch Scanned: 2026-10-14 (Provisional: the action test and the assistant citation check still to come; the hatched part of the bar is not measured yet.) Vietnam is hard for agents to use. ## Direct links - Menu: https://restaurant-vietnam.ch/menu/ - Phone: +41 43 333 19 39 ## What to fix first - **No structured data for the business.** (+15 points) Add schema.org JSON-LD for the business (Restaurant, LocalBusiness or the closest type, with name, address, telephone and openingHoursSpecification, plus servesCuisine and acceptsReservations). It is the one block every assistant reads first; the fix kit below has it filled in. Guide: https://directindex.org/guides/structured-data-restaurant - **Ordering only through ubereats.** (+12 points) Every agent transaction goes through the marketplace and its commission. Add a direct path on your own site, even a simple form. Guide: https://directindex.org/guides/online-ordering-without-delivery-apps - **The server turns AI crawlers away at the door.** (+6.7 points) Live fetches as GPTBot (http_403), ClaudeBot (http_403) were refused while a normal browser got the page. This is usually a hosting or firewall bot list 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, still worth doing) Optional today, cheap to add: a short text file describing the business for language models. Guide: https://directindex.org/guides/llms-txt-for-a-business ## Fix kit: What to paste Structured data (JSON-LD). One block in the page's head, or in the builder's custom-code slot. Replace anything that is wrong. ```html ``` llms.txt. Save as /llms.txt at the root of the site. ``` # Vietnam > restaurant (vietnamese) in Zurich.
