Top issues to fix

7 issues found · 2 high priority

  • Missing meta description

    SEO

    Add a ~150-character meta description to control your search-result snippet and lift click-through rate.

  • 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.

  • Missing X-Frame-Options header

    Security

    Add X-Frame-Options (or a CSP frame-ancestors rule) to prevent clickjacking via hidden iframes.

  • 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.

  • Missing OpenGraph tags

    SEO

    Add og:title/og:description/og:image so shared links render a proper preview card.

  • Heavy page (2.1 MB)

    Performance

    Aim for under 2 MB: compress images and split large JavaScript bundles.
