# Der Kern: Agent-Direct Score F (28.2%) Site: http://www.derkern.info/ Report: https://directindex.org/r/derkern.info 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.) Der Kern is largely invisible to agents. Some AI assistants are turned away by Der Kern's website. It can't find a menu or price list, so it answers from other sites. It can't find a link to book or order online. ## Direct links - Address: Hohlstrasse 48, 8004, Zürich ## Nearby, also direct Places near Der Kern that take a booking or an order on their own website, with no marketplace in between. - RED LIPS | Strip Club | Cabaret | Night Club (20 m): https://directindex.org/r/red-lips.ch - ANOAH Secret Bar (60 m): https://directindex.org/r/anoah.ch - Aladin (90 m): https://directindex.org/r/bistro-aladin.ch - Stereo (100 m): https://directindex.org/r/stube.me ## What to fix first - **No structured data for the business.** (+15 points) Add schema.org JSON-LD for the business (CafeOrCoffeeShop, BarOrPub or the closest type, with name, address, telephone and openingHoursSpecification, plus servesCuisine). Every assistant reads this block first, and the fix kit below has it filled in. Guide: https://directindex.org/guides/structured-data-restaurant - **No booking or ordering link on the website.** (+15 points) There's no link on the site for an agent to follow. If you take bookings or orders through a platform, link to it from the site so agents can find it. 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 page with the menu or price list 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 - **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 Zurich, 21% 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. ``` # Der Kern > local business in Hohlstrasse 48, 8004, Zürich, Zurich cafes and bars. ## About - Website: http://www.derkern.info/ - 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. ## Where it stands 472 of 571 in Zurich cafes and bars.
