The assistants haven't been asked about this business yet. They're asked about the top-ranked businesses in each city index, and about any business as soon as it's claimed. Claim this page to be included.

After the top fixes

Findings

What to fix first

  1. The site turns away every visitor that isn't a browser, AI agents included +25 points

    A plain fetch was refused (TimeoutError: The operation was aborted due to timeout). 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

  2. No list of services and prices found +7 points

    Agents answer 'what do they treat and what does it cost?' from directories instead. Add a page that lists services and prices as text, and link to it from the homepage. How to fix it

  3. Structured data is incomplete +6 points

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