Web Accessibility (WCAG 2.1): Why It Matters for SEO, UX, and Compliance
Web accessibility ensures that all users, including those with visual, auditory, or motor impairments, can perceive, navigate, and interact with your digital products.
1. Semantic HTML Is the Foundation of Accessibility
Using proper semantic elements (<header>, <nav>, <main>, <article>) allows screen readers and search crawlers to interpret page structure naturally without guessing.
2. WCAG AA Contrast Ratios (Minimum 4.5:1)
Ensure all text elements meet a minimum 4.5:1 contrast ratio against their background container, ensuring comfortable readability for all viewers in varying light conditions.
