Top Priorities (5)

Sorted by impact
Critical: 1

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
Critical: 2

No favicon or icon links detected

Without a favicon, your tab shows a blank icon and bookmarks look unbranded — amateur signal in every browser surface.

Accessibility › Favicon & Branding
Warning: 3

40 third-party resources (100% of weight)

Informational: third-party resource count and their share of page weight. High share caps perf gains from frontend optimization.

Performance › Page Weight Inventory
Warning: 4

Cross-Origin-Embedder-Policy header is missing

COEP enforces that all embedded resources opt-in to cross-origin embedding — required for cross-origin isolation features.

Security › Security Headers
Warning: 5

Cross-Origin-Opener-Policy header is missing

COOP isolates your top-level browsing context from cross-origin windows — without it, popup-based side-channel attacks remain possible.

Security › Security Headers
What fixing these means. Your site performs reasonably well, but a few targeted fixes could meaningfully improve results. Your LCP of 13.5s exceeds Google's 2.5s 'Good' threshold and the 1 performance issue below directly contributes 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 audience reach.
2 accessibility issues exclude users who rely on assistive technology.
Your LCP is 13.5s — fixing the 1 performance critical could bring it under Google's 2.5s 'Good' threshold.
2 security gaps detected — browsers may warn visitors about your site.

  • Page takes 13.5s to load
    Users abandon at ~3s — you're 11.0s over the 2.5s threshold
    → Optimize render-blocking resources, preload the hero image, and compress images
  • Page feels frozen for 772ms
    Clicks on the primary CTA are ignored while JavaScript runs
    → Break up long tasks; defer non-critical JavaScript to post-hydration
  • No viewport meta tag
    Mobile browsers render at desktop width and shrink — text unreadable, tap targets miniature
    → Add <meta name="viewport" content="width=device-width, initial-scale=1">
  • 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
  • No Open Graph tags
    Links shared on LinkedIn / Slack / Facebook show bare URLs — referral clicks drop
    → Add og:title, og:description, og:image, og:url to the page head

Observations (2)

Server version exposed in headers

The Server header reveals 'IIS 10.0'. Exposing exact server versions helps attackers target known vulnerabilities. Consider configuring your server to hide version information.

No build tool detected

A framework (Google Search Console) 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.
