Top Priorities (5)

Sorted by impact
Critical: 1

Connection is not encrypted (plain HTTP)

Plain-HTTP sites leak everything — credentials, session cookies, browsing history — to anyone on the network path.

Security › TLS & Certificates
Critical: 2

Content-Security-Policy header is missing

Without a CSP, a single XSS bug can exfiltrate everything your users type — including credentials.

Security › Security Headers
Critical: 3

Cookie 'crumb' is missing the Secure flag

A cookie without the Secure flag can leak over HTTP — in HSTS-protected sites, this is still a defense-in-depth gap.

Security › Cookie Security
Critical: 4

HSTS header is missing

Without HSTS, a network attacker can downgrade the very first connection to HTTP and steal the user's session.

Security › Security Headers
Critical: 5

1 link(s) with no accessible text

Links with no accessible text (empty <a></a>, image-only no alt, icon-only no aria-label) are unidentifiable to screen readers.

Accessibility › Link & Button Quality
What fixing these means. Your site performs reasonably well, but a few targeted fixes could meaningfully improve results. Addressing the critical issues below would have the most immediate impact on your user trust.
4 security gaps detected — browsers may warn visitors about your site.
1 accessibility issue excludes users who rely on assistive technology.

Figures combine localized regulatory fine ceilings, search/conversion value priced against local CPC, and bandwidth waste estimates. Results depend on implementation quality and audience composition. Not legal or financial advice.

  • Page takes 12.7s to load

    → Optimize render-blocking resources, preload the hero image, and compress images
  • Page feels frozen for 1.7s
    Clicks on the primary CTA are ignored while JavaScript runs
    → Break up long tasks; defer non-critical JavaScript to post-hydration
  • Site is not served over HTTPS
    Browsers show "Not Secure" in the URL bar — visitors abandon before reading
    → Install a TLS certificate (Let's Encrypt is free) and redirect HTTP → HTTPS
  • No HSTS header
    Returning visitors are briefly exposed to downgrade attacks on first request
    → Set Strict-Transport-Security: max-age=31536000; includeSubDomains
  • No Content-Security-Policy header
    Higher XSS blast radius — one compromised script can exfiltrate the checkout form
    → Ship a reporting-only CSP first, then enforce once violations are clean

Observations (2)

No build tool detected

A framework (Adobe Fonts) was detected but no bundler was identified. The build tool may not be detectable from output patterns, or the site may use the framework's built-in bundler.

Complex technology stack detected

12 technologies identified. A complex stack increases maintenance burden and attack surface. Consider whether all components are actively needed.
