Top issues to fix

6 issues found · 2 high priority

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.
1 cookie without Secure/HttpOnly flags
Security
Set Secure and HttpOnly on session cookies so they can't leak over HTTP or be read by injected scripts.
No structured data (JSON-LD) found
SEO
Add JSON-LD (Organization, Article, Product…) to become eligible for rich results.
Missing html lang attribute
Accessibility
Set <html lang="…"> so screen readers pick the right pronunciation rules.
2 broken links on the page
SEO
Fix or remove broken links — they waste crawl budget and erode user trust.
