Landmark Structure
Action12 landmarks
12 landmarks
Critical::
No <main> landmark found
Screen reader users cannot quickly navigate to the primary content. Wrap your main content in <main>.
Info::
12 <nav> landmark(s) found
Warning::
12 of 12 <nav> elements are unlabeled
Multiple navigations need aria-label to distinguish them for screen readers.
Info::
No banner (header) landmark
Info::
No contentinfo (footer) landmark
Warning::
Skip navigation link is missing (WCAG 2.4.1)
Add a skip link as the first focusable element so keyboard users can bypass repeated navigation.
Page Structure — as a screen reader sees it
Screen reader users cannot quickly navigate to the primary content. Wrap your main content in <main>.
Why this matters
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.
Learn more ▾ ▴
The <main> element marks the page's primary content area. Assistive tech offers a 'jump to main' shortcut — but only if <main> exists. Without it, every page navigation forces re-reading the header. Wrap your primary content in a single <main>.
Source: WAI-ARIA / WCAG 2.4.1
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.

Skipping heading levels breaks the document outline. Screen readers may interpret missing levels as structural errors.
Why this matters
Skipping heading levels breaks the document outline — screen-reader users lose track of section nesting.
Learn more ▾ ▴
Screen reader users navigate by jumping between headings (H1 → H2 → H3). Skipping (H1 → H3) breaks the sense of hierarchy. Use sequential levels even if you don't like the default styling — restyle with CSS instead. WCAG 1.3.1 (Info and Relationships) treats this as an A failure.

Why this matters
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.

No `<meta name="theme-color">` -- browser chrome falls back to default
Without `theme-color`, Android Chrome's status bar and iOS Safari's toolbar fall back to a generic gray. Adding a single hex color in `<meta name="theme-color" content="#0066cc">` tints them to your brand color across all mobile browsers.
Info::
Viewport `viewport-fit=cover` -- supports notched / dynamic-island devices
The viewport meta declares `viewport-fit=cover`, which lets the page draw into the safe-area edges (notch, dynamic island, home indicator) on iPhone X+ devices. Pair with `env(safe-area-inset-*)` CSS to keep critical UI inside the inset rectangle while letting backgrounds extend edge-to-edge.

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.
