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.
Missing X-Content-Type-Options header
Security
Add X-Content-Type-Options: nosniff to stop MIME-sniffing attacks.
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.
Title longer than 60 characters
SEO
Shorten the title to under 60 characters so search results don't truncate it.
Meta description longer than 160 characters
SEO
Trim the meta description to under 160 characters to avoid truncation in search results.
