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 "アカウント" 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.

Heading Hierarchy
No headings
REVIEW
No headings
Warning::
No headings found
Headings (H1-H6) create the document outline for screen reader navigation.

No headings found

Headings create the document outline for screen reader navigation.

Headings (H1-H6) create the document outline for screen reader navigation.

Why this matters

A page with zero headings is unnavigable by assistive tech and reads as one undifferentiated wall of text.

Learn more ▾

Screen reader users navigate by jumping between H1-H6 elements. A page with no headings has no skip targets — users have to read every word linearly. Adding a heading hierarchy (one H1, then H2 sections, optional H3 subsections) makes the page skimmable for both AT and human readers.

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.

Best practices

Touch targets with sufficient size and spacing help users who may have difficulty targeting small controls to activate the targets. Learn more about touch targets.

Why this matters

Performance issues directly impact user engagement and conversion rates.
