Top Priorities (5)

Sorted by impact
Critical: 1

Page weighs 16.3 MB (7.8 MB transferred)

Informational: total page weight (uncompressed) and bytes actually transferred over the wire.

Performance › Page Weight Budget
Critical: 2

3 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
Critical: 3

5 button(s) with no accessible text

Buttons with no accessible text (icon-only, no aria-label) can't be activated by voice control or understood by screen readers.

Accessibility › Link & Button Quality
Warning: 4

241 HTTP requests — consider bundling or reducing

High HTTP request count — bundling, sprite-ing, and HTTP/2 server push can reduce per-request overhead.

Performance › Page Weight Budget
Warning: 5

Cookie 'AMP_e3e918f274__middleware_new_session' is missing the HttpOnly flag

Without HttpOnly, JavaScript can read the cookie — an XSS bug becomes a session-stealing attack.

What fixing these means. Your site performs reasonably well, but a few targeted fixes could meaningfully improve results. Your LCP of 27.5s exceeds Google's 2.5s 'Good' threshold and the 2 performance issues below directly contribute to it. Accessibility issues exclude users who rely on assistive technology — an estimated 15% of your potential audience. Addressing the critical issues below would have the most immediate impact on your conversion rate.
Your LCP is 27.5s — fixing the 2 performance criticals could bring it under Google's 2.5s 'Good' threshold.
2 accessibility issues exclude users who rely on assistive technology.
1 security gap detected — browsers may warn visitors about your site.

    → Optimize render-blocking resources, preload the hero image, and compress images
  • Page feels frozen for 2.7s
    Clicks on the primary CTA are ignored while JavaScript runs
    → Break up long tasks; defer non-critical JavaScript to post-hydration
  • 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
  • Content is hard to read
    Graduate-level reading difficulty — limits the addressable audience for product or blog pages
