Top issues to fix
15 issues found · 7 high priority
TLS certificate expires in -247 days

Missing Content-Security-Policy header
SecurityAdd a CSP to control which sources can run scripts — the strongest single defense against XSS.
Missing title tag
SEOAdd a unique, descriptive <title> tag — it's the single most important on-page SEO element.
Missing meta description
SEOAdd a ~150-character meta description to control your search-result snippet and lift click-through rate.
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.
