# Kuffner Sternwarte: Agent-Direct Score F (24.5%)

Site: https://kuffner-sternwarte.at/
Report: https://directindex.org/r/kuffner-sternwarte.at
Scanned: 2026-10-15 (Provisional: the action test and the assistant citation check still to come; the hatched part of the bar is not measured yet.)
Kuffner Sternwarte 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 (TouristAttraction, Museum, TravelAgency or the closest type, with name, address, telephone and openingHoursSpecification). 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 way to buy tickets online.** (+15 points) Agents have nothing to act on. Add a ticket or booking page on your own domain. Guide: https://directindex.org/guides/book-direct-on-your-own-website
- **No tickets and prices found.** (+7 points) Agents answer 'what does it cost and when' from marketplaces instead. Add a page with tickets, times and prices as text and link it from the homepage. Guide: https://directindex.org/guides/menu-pdf-ai
- **robots.txt blocks GPTBot, OAI-SearchBot, ChatGPT-User.** (+3.8 points) These are the crawlers behind ChatGPT, Claude, Perplexity and Google's AI features. Remove the Disallow lines for them, or add explicit Allow rules. Guide: https://directindex.org/guides/robots-txt-for-ai-agents
- **The server turns AI crawlers away at the door.** (+3.4 points) Live fetches as ClaudeBot (http_429) 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
- **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.
