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 (missing!) CONTENTINFO (missing!)

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.

Mobile-Readable Font Sizes
97% of visible text renders at >= 12 CSS px (3 below threshold)
REVIEW
97% of visible text renders at >= 12 CSS px (3 below threshold)
Info::
3 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: <a> 10.0px ("PRIVACY\u00a0POLICY"); <a> 10.0px ("COOKIE\u00a0POLICY"); <a> 10.0px ("TERMS\u00a0OF\u00a0BUSINESS").

PWA Depth
3 PWA signal(s) surfaced
REVIEW
3 PWA signal(s) surfaced
Warning::
Manifest is missing `display` -- defaults to browser, no PWA UX
When `display` is `browser` (or unset, which is the spec default), the installed app opens in a regular browser tab -- no install prompt, no standalone window, no app-shell experience. The intended values for a PWA are `standalone` (most common; full-screen, no browser chrome) or `fullscreen` (games / immersive apps). `minimal-ui` is a middle ground (basic browser controls but no address bar).
Info::
Manifest has no maskable icon
Android 12+ Adaptive Icons crop non-maskable icons to a circle or squircle -- frequently hiding important parts of the logo. Add at least one icon entry with `"purpose": "maskable"` (or `"any maskable"`) and a maskable-aware design (16% safe-zone padding around the inner mark).
Info::
Manifest is missing `theme_color`
Without `theme_color`, the install prompt and Android status bar fall back to a generic tint instead of your brand color. Add a hex color (e.g. `"theme_color": "#0066cc"`); for richer support, mirror it via `<meta name="theme-color" content="#0066cc">` so non-installed browsers also pick it up.

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.
