Charles Darwin House

charlesdarwinhouse.co.uk is partly visible to agents.

This listing was retired on 2026-10-21 because the source the index uses for its city no longer lists it. The report stays up, but the business is left out of the rankings and counts.

Listed by Overture Maps.

Owners

Findings

What to fix first

  1. Structured data is incomplete +7 points

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

  2. No tickets and prices found +7 points

    Agents answer 'what does it cost and when?' from marketplaces instead. Add a page with tickets, times and prices as text, and link to it from the homepage. How to fix it

  3. No working HTTPS +3 points

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

  4. 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
