Prenzl Zahnärzte is hard for agents to use.

## What to fix first
- **No structured data for the business.** Add schema.org JSON-LD for the business (Restaurant, LocalBusiness or the closest type) with name, address, telephone and openingHoursSpecification, plus servesCuisine and acceptsReservations for a restaurant. It is the one block every assistant reads first. Guide: https://directindex.org/guides/structured-data-restaurant
- **No menu or price list found.** Agents answer 'what do they offer' from marketplaces instead. Add a menu or price list page and link it from the homepage. Guide: https://directindex.org/guides/menu-pdf-ai
- **No booking or ordering path at all.** 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
- **No llms.txt.** 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

## Already right
- **robots.txt lets AI crawlers in.** No rule blocks the key AI user agents.
- **AI crawlers get the page.** GPTBot, ClaudeBot and PerplexityBot all received a normal response.
