## What to fix first
- **The site turns every visitor without a browser away, AI agents included.** (+25 points) A plain fetch was refused (http_403); only a real browser got the page. Every AI crawler and agent is turned away the same way, so Reachable scores 0 and the rest is measured on the rendered page. Ask the host to let the AI user agents through. Guide: https://directindex.org/guides/blocking-ai-crawlers-without-knowing
- **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

## 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.
