Missing meta description
SEOAdd a ~150-character meta description to control your search-result snippet and lift click-through rate.

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
