Biggest gaps for Audio & Music Streaming sites

The checks with the most room to improve, weighted by impact.

HSTS kept for at least a year
33% observed · all sites 34%
Send Strict-Transport-Security on HTTPS responses. Start with a short max-age (for example 300 seconds), confirm every subdomain works over HTTPS, then raise it in steps to 31536000. Add includeSubDomains only when all subdomains are HTTPS. HSTS preload is optional and hard to undo; hstspreload.org itself does not recommend it by default.
