    Add a CSP to control which sources can run scripts — the strongest single defense against XSS.

    Add a ~150-character meta description to control your search-result snippet and lift click-through rate.

  • Missing X-Content-Type-Options header

    Security

    Add X-Content-Type-Options: nosniff to stop MIME-sniffing attacks.

  • Missing X-Frame-Options header

  • Missing canonical link

    SEO

    SEO
