Hoang Yen Hotpot is hard for agents to use.
Some AI assistants are turned away by Hoang Yen Hotpot's website. It can't find a menu or price list, so it answers from other sites. It can't find a link to book or order online.

- BanTianYao BBQ & FishPot·半天妖烤鱼·Vạn Hạnh Mall (1.6 km): https://directindex.org/r/bantianyao.vn

## What to fix first
- **No booking or ordering link on the website.** (+15 points) There's no link on the site for an agent to follow. If you take bookings or orders through a platform, link to it from the site so agents can find it. Add a booking or ordering page on your own domain. Guide: https://directindex.org/guides/book-direct-on-your-own-website
- **Structured data is incomplete.** (+7 points) Missing: address, telephone, opening hours. Guide: https://directindex.org/guides/structured-data-restaurant
- **No menu or price list found.** (+7 points) Agents answer 'what do they offer?' from marketplaces instead. Add a page with the menu or price list and link to it from the homepage. Guide: https://directindex.org/guides/menu-pdf-ai
- **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
- **No llms.txt.** (no points, but worth doing) Optional for now and cheap to add. It's a short text file that describes the business for language models. Guide: https://directindex.org/guides/llms-txt-for-a-business

## Fix kit: What to paste

Structured data (JSON-LD). Paste it as one block in the page's head, or in the builder's custom code box. Change anything that's wrong.
