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 H1 heading found

No H1 means screen-reader users can't identify the page's primary topic, and Google's content-extraction degrades.

Accessibility › Heading Hierarchy
Warning: 3

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: 4

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
Warning: 5

DMARC policy is none — monitoring only

DMARC p=none collects reports but doesn't actually block spoofed mail — phishing emails still reach inboxes.

Security › Email Security
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 audience reach.
2 accessibility issues exclude users who rely on assistive technology.
3 security gaps detected — browsers may warn visitors about your site.

Business case

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 4.4s to load
    Users abandon at ~3s — you're 1.9s over the 2.5s threshold
    → Optimize render-blocking resources, preload the hero image, and compress images
  • Mixed content on HTTPS page
    Browsers block insecure subresources — broken images, missing scripts, warning badge
    → Change http:// URLs inside the page to https:// (or protocol-relative)
  • 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
  • No structured data
    No rich-result eligibility in Google — lower SERP CTR vs competitors with stars and prices
    → Add JSON-LD for your page type (Product, Article, FAQPage, LocalBusiness, …)

Observations (2)

No build tool detected

A framework (HSTS) 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

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