After the top fixes
With the three fixes above (No booking or ordering link on the website; Structured data is incomplete; No menu or price list found), the score would be about 95.4%. That would be 7th of 6,873 in Tokyo, up from 2188th.
Peers are the businesses in the same index that have a reachable site, using the latest scan of each. The rank comes from the index's current ranking.
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. How to fix it
- Structured data is incomplete +7 points
Missing: address, telephone, opening hours. How to fix it
- 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. How to fix it
