Findings

What to fix first

  1. 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

  2. No online booking link on the website +13 points

    There's only a phone number or WhatsApp, and agents can't use those yet. If you take bookings or orders through a platform, link to it from the site so agents can find it. Add an online appointment page. 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. No working HTTPS +3 points

    The page is only served over plain http. Browsers and agents rank it lower or refuse it.

  5. No llms.txt no points, but worth doing

    Optional for now and cheap to add. It's a short text file that describes the business for language models. How to fix it
