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.
Missing viewport meta tag
