牡蠣と魚 海宝 is hard for agents to use.
An AI assistant can open 牡蠣と魚 海宝's website. It can read what 牡蠣と魚 海宝 offers. To book or order, it is sent to HotPepper, a marketplace.

- リストランテ エン (110 m): https://directindex.org/r/capolavoro.tokyo

## What to fix first
- **No structured data for the business.** (+15 points) Add schema.org JSON-LD for the business (Restaurant, LocalBusiness or the closest type, with name, address, telephone and openingHoursSpecification, plus servesCuisine and acceptsReservations). Every assistant reads this block first, and the fix kit below has it filled in. Guide: https://directindex.org/guides/structured-data-restaurant
- **Booking only through hotpepper.** (+12 points) Every transaction an agent makes goes through the marketplace, which takes its commission. Add a direct way on your own site. Even a simple form will do. Guide: https://directindex.org/guides/book-direct-on-your-own-website
- **No working HTTPS.** (+3 points) The page is only served over plain http. Browsers and agents rank it lower or refuse it.
- **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

## What the site tells visitors (Measured, not scored)
- **The footer says © 2019.** Visitors and assistants may read that year as the last time anyone looked after the site.
- **No English version declared.** Visitors from abroad, and assistants answering in English, read the page as it is.

## 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.

```html
<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@type": "Restaurant",
  "name": "牡蠣と魚 海宝",
  "url": "http://www.kaihou.jp",
  "geo": {
    "@type": "GeoCoordinates",
    "latitude": 35.7136321,
    "longitude": 139.7059416
  },
  "hasMenu": "http://www.kaihou.jp/menu00.html"
}
</script>
```

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