Top issues to fix

Missing Strict-Transport-Security header
Security
Add HSTS so browsers always use HTTPS — this closes the protocol-downgrade attack window.
Missing Content-Security-Policy header
Security
Add a CSP to control which sources can run scripts — the strongest single defense against XSS.
Over half of images are missing alt text
Accessibility
Add alt attributes to images — screen readers depend on them, and they help image SEO.
Missing X-Content-Type-Options header
Security
Add X-Content-Type-Options: nosniff to stop MIME-sniffing attacks.
Missing X-Frame-Options header
Security
Add X-Frame-Options (or a CSP frame-ancestors rule) to prevent clickjacking via hidden iframes.
2 cookies without Secure/HttpOnly flags
Security
Set Secure and HttpOnly on session cookies so they can't leak over HTTP or be read by injected scripts.
