## What to fix first
- **No way to buy tickets online.** (+13 points) Only a phone number or WhatsApp. Agents cannot act on those yet. Add a ticket or booking page. 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
- **Structured data is incomplete.** (+6 points) Missing: address, telephone, opening hours. Guide: https://directindex.org/guides/structured-data-restaurant
- **robots.txt blocks GPTBot, ClaudeBot, Google-Extended.** (+3.7 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
- **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
