Top Priorities (5)

Sorted by impact
Critical: 1

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: 2

Page weighs 10.6 MB (8.5 MB transferred)

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

Performance › Page Weight Budget
Critical: 3

2 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: 4

No <main> landmark found

Without a <main> landmark, screen-reader users can't skip past the navigation to the page content — every page starts with re-reading the menu.

Accessibility › Landmark Structure
Warning: 5

is missing width/height — may cause layout shift

Performance issues directly impact user engagement and conversion rates.

Performance › Image Optimization
What fixing these means. Your site performs reasonably well, but a few targeted fixes could meaningfully improve results. Your page blocks user input for 540ms — visitors may think the site is frozen. 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 user trust.
1 security gap detected — browsers may warn visitors about your site.
2 performance issues — Akamai's research found 53% of mobile users abandon pages over 3s.
2 accessibility issues exclude users who rely on assistive technology.

  • High main-thread blocking time
    Page is non-interactive for 540ms after first paint
    → Defer third-party scripts and split large bundles
  • 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
    → Shorten sentences; replace jargon with plain language; target Flesch ease ≥60
  • 8 link(s) with generic text ("click here", "read more")
    Screen-reader users navigating by link list see no context — and search engines can't infer relevance
    → Rewrite with descriptive phrases that identify the destination

Observations (2)

No build tool detected

A framework (Alpine.js) 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

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