Top issues to fix

8 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.

  • 3 cookies 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.

  • Meta description longer than 160 characters

    SEO

    Trim the meta description to under 160 characters to avoid truncation in search results.

  • No structured data (JSON-LD) found

    SEO

    Add JSON-LD (Organization, Article, Product…) to become eligible for rich results.

  • robots.txt not found

    SEO

    Publish /robots.txt with a Sitemap: directive to guide crawlers.
