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.
TLS certificate expires in 25 days
Security
Renew soon or enable auto-renewal to avoid a browser-warning outage.
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.
Title longer than 60 characters
SEO
Shorten the title to under 60 characters so search results don't truncate it.
