Top issues to fix

15 issues found · 4 high priority

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.
Over half of images are missing alt text
Accessibility
Add alt attributes to images — screen readers depend on them, and they help image SEO.
Missing viewport meta tag
Accessibility
Add <meta name="viewport" content="width=device-width, initial-scale=1"> — without it the site is broken on mobile.
Missing X-Content-Type-Options header
Security
Add X-Content-Type-Options: nosniff to stop MIME-sniffing attacks.
Missing X-Frame-Options header
Security
Add X-Frame-Options (or a CSP frame-ancestors rule) to prevent clickjacking via hidden iframes.
