Top issues to fix

10 issues found · 2 high priority

  • 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.

  • Slow estimated load (4.8s)

    Performance

    Use a CDN, enable caching/compression, and cut render-blocking assets — every extra second costs conversions.

  • Missing X-Content-Type-Options header

    Security

    Add X-Content-Type-Options: nosniff to stop MIME-sniffing attacks.

  • 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.

  • Meta description longer than 160 characters

    SEO

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

  • Missing canonical link

    SEO

    Add <link rel="canonical"> so search engines know which URL variant to index.
