Top issues to fix

10 issues found · 2 high priority

  • Missing Content-Security-Policy header

    Security

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

  • Over half of images are missing alt text

    Accessibility

    Add alt attributes to images — screen readers depend on them, and they help image SEO.

  • Missing X-Content-Type-Options header

    Security

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

  • Missing X-Frame-Options header

    Security

    Add X-Frame-Options (or a CSP frame-ancestors rule) to prevent clickjacking via hidden iframes.

  • Title longer than 60 characters

    SEO

    Shorten the title to under 60 characters so search results don't truncate it.

  • Missing canonical link

    SEO

    Add <link rel="canonical"> so search engines know which URL variant to index.
