Missing Content-Security-Policy header

Add a ~150-character meta description to control your search-result snippet and lift click-through rate.
Missing viewport meta tag

Add <meta name="viewport" content="width=device-width, initial-scale=1"> — without it the site is broken on mobile.
Missing X-Frame-Options header
Security
Add X-Frame-Options (or a CSP frame-ancestors rule) to prevent clickjacking via hidden iframes.
Missing canonical link
SEO
Add <link rel="canonical"> so search engines know which URL variant to index.
No structured data (JSON-LD) found
