Why Accessibility and Semantic Hierarchy Are Inseparable from SEO
Modern search engine spiders navigate web pages similarly to screen readers: parsing the Accessibility Object Model (AOM), inspecting ARIA landmark roles, and following logical heading trees. Replacing semantic HTML elements (<main>, <article>, <nav>) with generic nested <div> soup impairs Google’\”s ability to identify primary content, negatively impacting search indexation and AI answer extraction.

The Semantic Structural Audit
- Single <h1> Rule: Every page must possess exactly one descriptive
<h1>element matching its primary entity. - Landmark Regions: Explicitly wrap header nav in
<header>and<nav>, primary text in<main>, and sidebars in<aside>. - Form Labeling: Never rely exclusively on
placeholderattributes; always attach explicit<label for="...">elements.
