The website's grade

Some AI assistants are turned away by Dr. Marlene Serak's website. It can't find a menu or price list, so it answers from other sites. It finds a phone number, but no link to book or order online.

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. robots.txt blocks GPTBot, ClaudeBot, PerplexityBot, Google-Extended, OAI-SearchBot, ChatGPT-User, Claude-User, Perplexity-User +10 points

    These are the crawlers behind ChatGPT, Claude, Perplexity and Google's AI features. Remove the Disallow lines for them, or add explicit Allow rules. How to fix it

  4. The server turns AI crawlers away at the door +10 points

    Requests as GPTBot (http_403), ClaudeBot (http_403), PerplexityBot (http_403) were refused, but a normal browser got the page. That's usually a bot list at the host or in a firewall that the owner never chose. Ask the host to allow these user agents. How to fix it

  5. 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

  6. 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
