Missing meta description
SEOAdd a ~150-character meta description to control your search-result snippet and lift click-through rate.
Slow estimated load (7.2s)

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.
