Add a skip link as the first focusable element so keyboard users can bypass repeated navigation.
Page Structure — as a screen reader sees it
BANNER header NAV MAIN CONTENTINFO footer

Multiple navigations need aria-label to distinguish them for screen readers.

Why this matters

Some <nav> elements lack aria-label — screen-reader users hear 'navigation' multiple times with no way to distinguish them.

Learn more

When a page has multiple <nav> regions (primary, footer, breadcrumb), each needs aria-label or aria-labelledby. AT users navigate by landmark; identical 'navigation' announcements force them to enter each one to discover purpose.

Source: WAI-ARIA Authoring Practices

Add a skip link as the first focusable element so keyboard users can bypass repeated navigation.

Why this matters

Without a skip-nav link, keyboard users tab through every nav item before reaching content — every page, every visit.

Learn more

WCAG 2.4.1 (Bypass Blocks) requires a mechanism to skip past repeated content. The standard implementation is a 'Skip to main content' link that's the first focusable element, visually hidden until focused. Three lines of HTML + four of CSS.

B
Tap Target Adequacy
1 tap target(s) too small or too close together
REVIEW
1 tap target(s) too small or too close together
Info::
1 tap target(s) too small or too close to neighbors
WCAG 2.5.5 (Level AAA) requires interactive targets to be at least 44x44 CSS pixels; WCAG 2.5.8 (Level AA, added in 2.2) requires 24x24 minimum. Failing targets cause mis-taps for users with motor impairments, large fingers, or shaky hands -- and are a major bounce-rate driver on mobile commerce flows. Lighthouse measures rendered rects + adjacent-element spacing; the failing list is in the Lighthouse 'tap-targets' audit detail panel.
B
Mobile-Readable Font Sizes
91% of visible text renders at >= 12 CSS px (27 below threshold)
REVIEW
91% of visible text renders at >= 12 CSS px (27 below threshold)
Info::
27 text node(s) render below 12 CSS pixels on mobile
Mobile browsers default the root font-size to 16 px; text below ~ 12 px (75% of root) is hard to read without zooming. WCAG 1.4.4 (Resize Text) requires the page to support 200% zoom without loss of functionality -- which most layouts handle, but small base text still costs readability and conversion. Audit which selectors set sizes below 12 px (often footers, fine print, table cells) and bump them to 14-16 px or use rem units that scale with user preferences. Examples: <span> 11.0px ("50% OFF"); <span> 9.0px ("50% OFF"); <span> 10.0px ("Free"); <span> 10.0px ("Free"); <span> 10.0px ("Pro").

Accessibility

These checks highlight opportunities to improve the accessibility of your web app. Automatic detection can only detect a subset of issues and does not guarantee the accessibility of your web app, so manual testing is also encouraged.

Contrast

Low-contrast text is difficult or impossible for many users to read. Learn how to provide sufficient color contrast.

Why this matters

Performance issues directly impact user engagement and conversion rates.

Methodology: The top 20 text elements by font size were checked. Background color was sampled from the desktop screenshot using a 5-point pattern. WCAG 2.1 AA requires 4.5:1 for normal text and 3:1 for large text.

All checks on this page are automated. Results are estimates - run targeted manual reviews when the score affects a release decision.
