After the top fixes
With the three fixes above (The site turns away every visitor that isn't a browser, AI agents included; No menu or price list found; Structured data is incomplete), the score would be about 95.4%. That would be 19th of 581 in Brussels cafes and bars, up from 385th.
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
- The site turns away every visitor that isn't a browser, AI agents included +25 points
A plain fetch was refused (http_403). Only a real browser got the page. Every AI crawler and agent gets turned away the same way, so Reachable scores 0 and the rest is measured on the page as the browser rendered it. Ask the host to let the AI user agents through. 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
- Structured data is incomplete +5 points
Missing: telephone, opening hours. How to fix it
