Missing landmark elements — the fix
The page is missing one or more essential landmark elements (main, nav, or header). Landmarks help assistive technologies understand the page structure.
Where this fits: accessibility in SEO
Accessibility overlaps heavily with SEO because both depend on machine-readable structure: alt text, heading hierarchy, labels, contrast. Screen readers and search crawlers consume the same signals. Accessible sites rank better not by special treatment but because the same fixes — descriptive alt attributes, proper headings, real link text — are exactly what search engines parse for meaning. It is also, in a growing number of jurisdictions, the law.
Why missing landmark elements hurts your rankings
WCAG 1.3.1 requires that page structure is programmatically determinable. Landmarks provide a way for screen reader users to quickly navigate to major page sections. Without landmarks, users must linearly traverse all content to find what they need, significantly increasing navigation time.
This is a high-severity issue: it directly suppresses rankings or click-through on the pages it affects. It belongs in your current sprint, prioritised by how many pages carry it.
How to fix it
Use semantic HTML elements (<main>, <nav>, <header>, <footer>) to define the page structure. Every page should have at least a <main> element for primary content and <nav> for navigation.
<header>Site header and logo</header>
<nav>Navigation links</nav>
<main>Page content</main>
<footer>Footer content</footer>Accessibility best practices
- Give every informative image an alt attribute that describes its content; decorative images get alt="".
- Maintain heading hierarchy — never skip levels for styling reasons.
- Make link text meaningful out of context; screen readers list links in isolation.
- Keep text contrast at WCAG AA (4.5:1) minimum.
- Make everything keyboard-operable with a visible focus state.
