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.)
ISSHIN is partly visible to agents.

## Direct links
- Book directly: https://www.isshin-amsterdam.nl/reservation/ (on the business's own site)
- Order directly: https://www.isshin-amsterdam.nl/shop/ (on the business's own site)
- Menu: https://www.isshin-amsterdam.nl/menu/
- Phone: +31 20 6270607

## What to fix first
- **No structured data for the business.** (+14 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). It is the one block every assistant reads first; the fix kit below has it filled in. Guide: https://directindex.org/guides/structured-data-restaurant
- **The server turns AI crawlers away at the door.** (+3.3 points) Live fetches as PerplexityBot (http_429) were refused while a normal browser got the page. This is usually a hosting or firewall bot list the owner never chose. Ask the host to allow these user agents. Guide: https://directindex.org/guides/blocking-ai-crawlers-without-knowing
- **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.
