# Herzogenhof: Agent-Direct Score B (73.8%)

Site: https://herzogenhof-odenthal.de/
Report: https://directindex.org/r/herzogenhof-odenthal.de
Scanned: 2026-10-14 (Provisional: the action test and the assistant citation check still to come; the hatched part of the bar is not measured yet.)
Herzogenhof is mostly ready for agents.

## Direct links
- Book directly: https://www.opentable.de/widget/reservation/loader?rid=250770&type=standard&theme=standard&iframe=true&domain=de&lang=de-DE&newtab=false&ot_source=Restaurant%20website (through opentable acting for the business)
- Menu: https://herzogenhof-odenthal.de/wp-content/uploads/Speisekarte-13.10.2026.pdf
- Phone: +49 2202 9211755

## What to fix first
- **Structured data is incomplete.** (+6 points) Missing: address, telephone, opening hours. Guide: https://directindex.org/guides/structured-data-restaurant
- **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
- **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

## 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.
