Top issues to fix
13 issues found · 6 high priority
TLS certificate expires in 7 days
SecurityRenew now (or enable auto-renewal) — an expired certificate blocks visitors with a full-page browser warning.
Missing Strict-Transport-Security header
SecurityAdd HSTS so browsers always use HTTPS — this closes the protocol-downgrade attack window.
Missing Content-Security-Policy header
SecurityAdd a CSP to control which sources can run scripts — the strongest single defense against XSS.
Missing meta description
SEOAdd a ~150-character meta description to control your search-result snippet and lift click-through rate.
Over half of images are missing alt text
AccessibilityAdd alt attributes to images — screen readers depend on them, and they help image SEO.
Missing viewport meta tag
AccessibilityAdd <meta name="viewport" content="width=device-width, initial-scale=1"> — without it the site is broken on mobile.
