## What to fix first
- **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
- **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
- **Structured data is incomplete.** (+2 points) Missing: address. Guide: https://directindex.org/guides/structured-data-restaurant
