Top issues to fix

7 issues found · 3 high priority

  • Missing Strict-Transport-Security header

    Security

    Add HSTS so browsers always use HTTPS — this closes the protocol-downgrade attack window.

  • Missing Content-Security-Policy header

    Security

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

  • Missing meta description

    SEO

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

  • Missing X-Frame-Options header

    Security

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

  • Missing canonical link

    SEO

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

  • Multiple H1 headings found

    SEO

    Keep a single H1 per page and demote the others to H2/H3.
