Top Priorities (5)
Page weighs 5.8 MB (5.2 MB transferred)
Informational: total page weight (uncompressed) and bytes actually transferred over the wire.
2 button(s) with no accessible text
Buttons with no accessible text (icon-only, no aria-label) can't be activated by voice control or understood by screen readers.
Images are 4.8 MB — compress or use modern formats
Image bandwidth is high — modern formats (WebP/AVIF) and resizing typically cut it 50%+.
No DMARC record found
Without DMARC, anyone can send phishing emails using your domain name.
Page weight 4.2 MB over 1MB target
Performance issues directly impact user engagement and conversion rates.
Business case
What fixing the audit's findings is worth -- and what ignoring them keeps costing.
Return on investment
$500 investment → $5,587/month returns + USD 150,000 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
4 barrier(s) likely increasing bounce by ~14%.
- Page loads in 3.4sEvery additional 100ms above 2.5s costs conversions — you're 941ms over→ Target <2.5s LCP: defer non-critical scripts and optimize the hero image
- High main-thread blocking timePage is non-interactive for 408ms after first paint→ Defer third-party scripts and split large bundles
- No structured dataNo 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, …)
- No skip-to-content linkKeyboard and screen-reader users must tab through the entire header on every page→ Add a visible-on-focus <a href="#main">Skip to content</a> as the first focusable element
Preliminary CRO audit — each barrier links to the tab with detailed analysis.

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.
