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 (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

  2. No structured data for the business +14 points

    Add schema.org JSON-LD for the business (Dentist, MedicalClinic, Physiotherapy or the closest type, with name, address, telephone and openingHoursSpecification). Every assistant reads this block first, and the fix kit below has it filled in. How to fix it

  3. 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

  4. Appointments through an unrecognised third party no points, but worth doing

    Check that the provider keeps your business as the seller of record. How to fix it
