Top issues to fix
13 issues found · 4 high priority

Missing Content-Security-Policy header

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 X-Content-Type-Options header
SecurityAdd X-Content-Type-Options: nosniff to stop MIME-sniffing attacks.
Missing X-Frame-Options header
SecurityAdd X-Frame-Options (or a CSP frame-ancestors rule) to prevent clickjacking via hidden iframes.
