Why most business websites score under 40/100 for AI visibility — and what the signals actually are

Hey — I'm Stewart, founder of Technical Graffiti, launching here on 23 June.

Quick question for the community: have you ever checked whether your business or your clients' businesses actually appear in ChatGPT or Gemini when someone asks for a recommendation?

Most sites we check score between 20–40 out of 100. The gaps are almost always the same — no llms.txt, robots.txt blocking AI crawlers, no schema markup.

Happy to run a free check on anyone's domain here if useful. Takes 60 seconds: technicalgraffiti.co.uk/free-assessment/

What's your experience been with AI search visibility?
