Top Priorities (5)
HSTS header is missing
Without HSTS, a network attacker can downgrade the very first connection to HTTP and steal the user's session.
Page weighs 20.0 MB (5.7 MB transferred)
Informational: total page weight (uncompressed) and bytes actually transferred over the wire.
10 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.
2 image(s) missing alt attribute
Each image without alt text is a WCAG 1.1.1 failure — invisible to screen-reader users, lost from Google Image Search.
269 third-party resources (98% of weight)
Informational: third-party resource count and their share of page weight. High share caps perf gains from frontend optimization.
Business case
What fixing the audit's findings is worth -- and what ignoring them keeps costing.
Return on investment
BRL 405 investment → BRL 1,866/month returns + BRL 50,000,000 risk avoided
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.
Conversion barriers
8 barrier(s) likely increasing bounce by ~31%.
- Page takes 44.0s to loadUsers abandon at ~3s — you're 41.5s over the 2.5s threshold→ Optimize render-blocking resources, preload the hero image, and compress images
- Page feels frozen for 4.0sClicks on the primary CTA are ignored while JavaScript runs→ Break up long tasks; defer non-critical JavaScript to post-hydration
- 5 broken link(s) on the pageClicks land on 404s — trust drops and the session often ends→ Fix or remove the broken destinations surfaced on the Content tab
- No HSTS headerReturning visitors are briefly exposed to downgrade attacks on first request→ Set Strict-Transport-Security: max-age=31536000; includeSubDomains
- No Content-Security-Policy headerHigher XSS blast radius — one compromised script can exfiltrate the checkout form→ Ship a reporting-only CSP first, then enforce once violations are clean
Preliminary CRO audit — each barrier links to the tab with detailed analysis.

Compliance figures represent the statutory maximum fine for the most severe triggered category, capped per regulation — not the sum of per-finding penalties. Based on published regulatory fine ranges. This is not legal advice.

Observations (4)
jQuery loaded alongside a modern framework
Both jQuery and React are loaded. Modern frameworks handle DOM manipulation natively. jQuery may be unnecessary and adds ~30KB to the page weight. Check the Performance tab for bundle analysis.
No build tool detected
A framework (Babel) 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.
jQuery version may be outdated
Detected jQuery 1.8.3. The current major version is 3. Consider updating for security patches and new features.
Complex technology stack detected
29 technologies identified. A complex stack increases maintenance burden and attack surface. Consider whether all components are actively needed.
