Add a skip link as the first focusable element so keyboard users can bypass repeated navigation.
Without a skip-nav link, keyboard users tab through every nav item before reaching content — every page, every visit.

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.

BHeading HierarchyNo headingsREVIEW
No headings found
Headings create the document outline for screen reader navigation.
Headings (H1-H6) create the document outline for screen reader navigation.
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.
