Top Priorities (5)
8 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.
Missing <html lang> attribute (WCAG 3.1.1)
Missing <html lang> attribute -- screen readers default to the user's system language and pronounce content with the wrong phonetics.
No <main> landmark found
Without a <main> landmark, screen-reader users can't skip past the navigation to the page content — every page starts with re-reading the menu.
is missing width/height — may cause layout shift
Performance issues directly impact user engagement and conversion rates.
12 render-blocking <script src> tag(s) without async/defer

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
5 barrier(s) likely increasing bounce by ~26%.
- Page takes 23.6s to loadUsers abandon at ~3s — you're 21.1s over the 2.5s threshold→ Optimize render-blocking resources, preload the hero image, and compress images
- Page feels frozen for 1.0sClicks on the primary CTA are ignored while JavaScript runs→ Break up long tasks; defer non-critical JavaScript to post-hydration
- 9 link(s) with generic text ("click here", "read more")Screen-reader users navigating by link list see no context — and search engines can't infer relevance→ Rewrite with descriptive phrases that identify the destination
- 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
- 2 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
Preliminary CRO audit — each barrier links to the tab with detailed analysis.

A framework (Adobe Fonts) 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
25 technologies identified. A complex stack increases maintenance burden and attack surface. Consider whether all components are actively needed.
