What to do
Provide a way to bypass blocks repeated across pages (e.g., skip link, landmarks, headings).
Why it matters
Keyboard and screen reader users should not be forced to tab through the same navigation on every page.
Success criterion
What WCAG 2.4.1 requires
Summarized directly from the official Understanding document so teams can quote the requirement accurately.
A mechanism is available to bypass blocks of content that are repeated on multiple Web pages.
Intent
Why WCAG created this requirement
- Repeated blocks create significant keyboard navigation overhead.
- Bypass mechanisms improve efficiency and reduce fatigue.
- Landmarks and headings can also support bypass.
Benefits
Who gains when you pass
- Keyboard users can reach main content quickly.
- Screen reader users can navigate by landmarks/headings efficiently.
- Users with motor impairments reduce repetitive keystrokes.
Why it matters
User impact when this criterion fails
Summaries drawn from the Understanding document help you socialize impact statements with product stakeholders.
Users must tab through dozens of links before reaching main content.
Navigation fatigue can cause abandonment.
Overview
Provide skip navigation (or other bypass mechanisms) so users can jump past repeated blocks like headers, nav menus, and sidebars to reach the main content quickly.
- A visible-on-focus “Skip to main content” link is a common solution.
- Use landmarks (`<main>`, `<nav>`) and proper headings to support bypass.
- Ensure the skip target is focusable and moves focus correctly.

Examples
Make success tangible for teams
Share pass/fail snapshots to coach designers, engineers, QA, and content authors.
Skip link
Pass
First Tab reveals “Skip to main content”; Enter moves focus to `<main>`.
Fail
No skip mechanism; user must tab through full navigation every time.
Landmarks
Pass
Page has `<nav>` and `<main>` so screen readers can jump to main region.
Fail
Page uses only `<div>` wrappers, making bypass harder.
Evidence to keep
Document conformance decisions
Capture artifacts for VPATs, procurement reviews, and regression testing.
- Document standard layout landmarks and skip-link behavior across templates.
- Capture screenshots showing skip link visible on focus.

Quick Reference 2.4.1
Filterable list of sufficient techniques and failures.
Technique G1
Adding a link at the top of each page that goes directly to the main content area.
Technique ARIA11
Using ARIA landmarks to identify regions of a page.
Implementation checklist
Capture progress and blockers
- Add a “Skip to main content” link as the first focusable element on pages with repeated navigation.
- Ensure the main content area has an id and is focusable when targeted.
- Use semantic landmarks (`header`, `nav`, `main`, `footer`) consistently.
- Ensure skip links are visible on focus and work with keyboard and screen readers.
Testing ideas
Prove conformance with evidence
- Tab from the top of the page and verify a skip link appears early.
- Activate the skip link and confirm focus moves to main content.
- Verify the skip target is announced and focusable.
- Test multiple pages to confirm bypass works wherever navigation repeats.
