Top issues to fix

12 issues found · 6 high priority

  • No valid HTTPS/TLS certificate

    Security

    Serve the site over HTTPS (a free Let's Encrypt certificate works) — browsers mark HTTP sites as Not Secure and Google demotes them.

  • 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.

  • No H1 heading found

    SEO

    Add exactly one H1 describing the page's main topic — it anchors the document outline for search engines and screen readers.

  • Missing viewport meta tag

    Accessibility

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