EqualWeb – Semantic Structure Analyzer

Detailed Description EqualWeb Semantic Structure Analyzer is a comprehensive accessibility tool that helps developers understand and improve the semantic structure of their web pages according to WCAG 2.2 guidelines. Why Semantic Structure Matters Assistive technologies like screen readers rely on semantic HTML and ARIA landmarks to help users navigate and understand web content. Proper use of elements like <main>, <nav>, <header>, and <footer> creates a logical structure that makes websites accessible to everyone.
