Is there a free way to check how AI-ready a website is?

Yes. The free website checker reads any public website's home page the way Google and AI crawlers do and tells you in plain words what's helping and what's in the way. No sign-up and no card.

It looks at AI crawler access and llms.txt, the title and description, robots.txt, the sitemap, structured data, phone readiness, headings, photo descriptions, a secure address and one-tap calling. It doesn't log in, fill forms or store the pages it reads, and it can be run a few times an hour.

A high score means a site is easy to find and read, not that it will rank first. For your own AOS site, Site health in your dashboard goes much deeper and checks it every day.
