- The Vintage Emporium (390 m): https://directindex.org/r/vintageemporium.net

## 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
- **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
- **The phone number on the site doesn't match the open map data.** The site shows 0866801599, but OpenStreetMap or Overture Maps lists +84865819876. An assistant that sees two numbers can't tell which one to trust. Fix whichever is wrong, on the site or in the map data at openstreetmap.org.

## Fix kit: What to paste

llms.txt. Save as /llms.txt at the root of the site.
