Top issues to fix

9 issues found · 4 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 viewport meta tag

    Accessibility

    Add <meta name="viewport" content="width=device-width, initial-scale=1"> — without it the site is broken on mobile.

  • Missing canonical link

    SEO

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

  • No structured data (JSON-LD) found

    SEO

    Add JSON-LD (Organization, Article, Product…) to become eligible for rich results.
