Findings

What to fix first

  1. Structured data is incomplete +6 points

    Missing: address, telephone, opening hours. How to fix it

  2. Menu or price list is an image +6 points

    Agents can't read it. Publish it as text. How to fix it

  3. The phone number on the site doesn't match the open map data

    The site shows 0659826350, but OpenStreetMap or Overture Maps lists +31102188656. 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.
