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

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.

Add a skip link as the first focusable element so keyboard users can bypass repeated navigation.
Without a skip-nav link, keyboard users tab through every nav item before reaching content — every page, every visit.

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.

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.

Links with target="_blank" without rel="noopener" leak the originating page's window context — security and UX issue.
Learn more ▾ ▴
Without rel="noopener", the new tab can navigate the original tab via window.opener (tab-nabbing attack). Modern browsers default to noopener for target=_blank but only since recent versions. Always set rel="noopener noreferrer" explicitly.
