Top Priorities (5)

Sorted by impact
Critical: 1

'unsafe-inline' found in script source

Unsafe value (unsafe-inline, unsafe-eval) in script-src defeats CSP's main protection — XSS injections can execute again.

Security › Content Security Policy
Critical: 2

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
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 user trust.
4 security gaps detected — browsers may warn visitors about your site.
1 accessibility issue excludes users who rely on assistive technology.

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.

  • 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
  • Viewport disables user zoom
    Visitors with low vision can't read the page — and some jurisdictions treat this as a legal risk
    → Remove user-scalable=no; drop maximum-scale if it's below 2
  • 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
  • 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, …)

This technology has a CPE identifier — check for known vulnerabilities Search NVD →

HTTP Strict Transport Security (HSTS) informs browsers that the site should only be accessed using HTTPS.

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.

Minimal technology footprint

Only 2 technologies detected. This suggests a simple setup with minimal dependencies — excellent for performance and security.
