Top issues to fix
10 issues found · 3 high priority
Missing Strict-Transport-Security header

Missing Content-Security-Policy header
SecurityAdd a CSP to control which sources can run scripts — the strongest single defense against XSS.
No H1 heading found
SEOAdd exactly one H1 describing the page's main topic — it anchors the document outline for search engines and screen readers.
Missing X-Frame-Options header
SecurityAdd X-Frame-Options (or a CSP frame-ancestors rule) to prevent clickjacking via hidden iframes.
Meta description longer than 160 characters
SEOTrim the meta description to under 160 characters to avoid truncation in search results.
No structured data (JSON-LD) found
