Visible by AI Free 16-Check Self-Test

Visible by AI's free checker lets you paste a website address and runs 16 checks covering schema, robots.txt, AI crawler access, llms.txt and answer formatting over HTTPS. It returns a score plus the fixes that matter. The tool reads the homepage as a server-rendered document without running JavaScript, and also requests /robots.txt, /sitemap.xml and /llms.txt, which is four requests in total. It requires no signup, no email and no installation, and the page states it does not store results. It is described as an automated snapshot of the signals the paid audit starts from, not a prediction of ranking or citation.
