Findings

What to fix first

  1. No structured data for the business +15 points

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

  2. No booking or ordering link on the website +15 points

    There's no link on the site for an agent to follow. If you take bookings or orders through a platform, link to it from the site so agents can find it. Add a booking or ordering page on your own domain. 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. 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

  5. Almost no text without JavaScript +2 points

    Crawlers that don't run scripts see an empty page. Put the menu, hours and address in plain HTML. 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
