A page should have only one H1. Multiple H1s dilute the document outline.

Why this matters

Multiple H1s blur the page's primary topic — screen-reader users and Google both prefer one H1.

Learn more ▾

HTML5's outline algorithm technically allows multiple H1s within sectioning content, but no browser implements it. In practice: one H1 per page. Use H2-H6 for subsections.

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.

Page Structure — as a screen reader sees it
BANNER (missing!) NAV "navigation wrapper" MAIN (missing!) CONTENTINFO footer

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

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.

Placeholder text disappears on focus and is not a reliable label.

<input type="search" name="s">; <input type="search" name="s">; <input type="search" name="s">

Why this matters

Placeholder-only labels disappear when the user starts typing — they must remember what the field was for.

Learn more ▾

Placeholders are NOT labels. They vanish on input, fail color contrast checks (most are gray), and don't satisfy WCAG SC 3.3.2. Always use a real <label> alongside (or aria-labelledby).

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.

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.

Navigation

A value greater than 0 implies an explicit navigation ordering. Although technically valid, this often creates frustrating experiences for users who rely on assistive technologies. Learn more about the `tabindex` attribute.

Why this matters

Performance issues directly impact user engagement and conversion rates.

Failing Elements
Naar hoofdinhoud body.home > div#page-container > a.skip-link

Properly ordered headings that do not skip levels convey the semantic structure of the page, making it easier to navigate and understand when using assistive technologies. Learn more about heading order.

Why this matters

Performance issues directly impact user engagement and conversion rates.

These are opportunities to improve keyboard navigation in your application.

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.
