Android requires a 192x192 icon for 'Add to Home Screen' — without it, installed PWAs show a generic placeholder.
Business case
What fixing the audit's findings is worth -- and what ignoring them keeps costing.
Return on investment
$125 investment → $4,632/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
3 barrier(s) likely increasing bounce by ~12%.
- Page loads in 3.9sEvery additional 100ms above 2.5s costs conversions — you're 1.4s over→ Target <2.5s LCP: defer non-critical scripts and optimize the hero image
- 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 (Bulma) 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
16 technologies identified. A complex stack increases maintenance burden and attack surface. Consider whether all components are actively needed.
