Top issues to fix
12 issues found · 5 high priority
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.
No H1 heading found
SEOAdd exactly one H1 describing the page's main topic — it anchors the document outline for search engines and screen readers.
Over half of images are missing alt text
AccessibilityAdd alt attributes to images — screen readers depend on them, and they help image SEO.
1 cookie without Secure/HttpOnly flags
SecuritySet Secure and HttpOnly on session cookies so they can't leak over HTTP or be read by injected scripts.
