2 link(s) open in new tab without warning
Links with target="_blank" without rel="noopener" leak the originating page's window context — security and UX issue.
IPv6 DNS records exist but server is not reachable
Advertising IPv6 (AAAA records) without a reachable server means IPv6-preferring clients silently fail every connection.
Business case
What fixing the audit's findings is worth -- and what ignoring them keeps costing.
Return on investment

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
2 barrier(s) likely increasing bounce by ~6%.
- High main-thread blocking timePage is non-interactive for 248ms after first paint→ Defer third-party scripts and split large bundles
- Content is hard to readGraduate-level reading difficulty — limits the addressable audience for product or blog pages→ Shorten sentences; replace jargon with plain language; target Flesch ease ≥60

Observations (2)
No build tool detected
A framework (Apple) 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
8 technologies identified. A complex stack increases maintenance burden and attack surface. Consider whether all components are actively needed.
