# Silberkugel: Agent-Direct Score F (20.5%)

Site: http://www.silberkugel.ch/
Report: https://directindex.org/r/silberkugel.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.)
Silberkugel is largely invisible to agents.

## 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
- **No booking or ordering path at all.** (+15 points) Agents have nothing to act on. Add a booking or ordering page on your own domain. Guide: https://directindex.org/guides/book-direct-on-your-own-website
- **No menu or price list found.** (+7 points) Agents answer 'what do they offer' from marketplaces instead. Add a menu or price list page and link it from the homepage. Guide: https://directindex.org/guides/menu-pdf-ai
- **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 working HTTPS.** (+3 points) The page is only served over plain http. Agents and browsers downrank or refuse it.
- **Almost no text without JavaScript.** (+2 points) Crawlers that do not run scripts see an empty page. Render the menu, hours and address as plain HTML. Guide: https://directindex.org/guides/website-blank-without-javascript
- **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.
