## What to fix first
- **No booking or ordering path at all.** (+13 points) Only a phone number or WhatsApp. Agents cannot act on those yet. Add a booking or ordering page. Guide: https://directindex.org/guides/book-direct-on-your-own-website
- **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
- **Menu or price list is a PDF.** (+3 points) Most agents skip PDFs or read them badly. Publish it as HTML, keep the PDF as a download. Guide: https://directindex.org/guides/menu-pdf-ai

## Fix kit: What to paste

robots.txt. Add these lines to /robots.txt and delete any Disallow rule that names these crawlers.

```
# Let AI assistants read the site: they send people to you; a marketplace keeps them.
# Remove any Disallow lines for these names elsewhere in this file.
