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.
No H1 heading found
SEO
Add exactly one H1 describing the page's main topic — it anchors the document outline for search engines and screen readers.
Slow estimated load (12.8s)
Performance
Use a CDN, enable caching/compression, and cut render-blocking assets — every extra second costs conversions.
Missing X-Content-Type-Options header
Security
Add X-Content-Type-Options: nosniff to stop MIME-sniffing attacks.
Meta description longer than 160 characters
SEO
Trim the meta description to under 160 characters to avoid truncation in search results.
