Top issues to fix

Missing Content-Security-Policy header

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.
Title longer than 60 characters
SEO
Shorten the title to under 60 characters so search results don't truncate it.
Missing canonical link

Add <link rel="canonical"> so search engines know which URL variant to index.
Multiple H1 headings found
