Site: https://changthai.koeln/
Report: https://directindex.org/r/changthai.koeln
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.)
Chang Thai is partly visible to agents.
An AI assistant can open the website of Chang Thai. It finds no menu or price list, so it answers from other sites. It finds no link to book or order online, only a phone number.

## Direct links
- Phone: +49 221 29966093

## What to fix first
- **No booking or ordering link on the website.** (+13 points) Only a phone number or WhatsApp, which agents cannot use yet. If you take bookings or orders through a platform, link to it from the site so an agent can find it. Add a booking or ordering page. Guide: https://directindex.org/guides/book-direct-on-your-own-website
- **No menu or price list found.** (+7 points) 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
- **Structured data is incomplete.** (+6 points) Missing: address, telephone, opening hours. Guide: https://directindex.org/guides/structured-data-restaurant
- **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.
