Accessibility & Core Web Vitals – A 2025 Power Duo

Google’s Core Web Vitals (LCP, FID, CLS) remain key SEO ranking factors in 2025. What many do not realise is that accessibility improvements often improve these metrics, creating a win-win for SEO and usability.

How Accessibility Boosts Core Web Vitals

• Largest Contentful Paint (LCP): Alt text and optimised images improve load speed and content clarity.
• First Input Delay (FID): Keyboard and voice navigation reduce interaction friction.
• Cumulative Layout Shift (CLS): Stable, predictable layouts benefit all users, especially those with cognitive impairments.

Compliance Standards and Performance
By meeting WCAG 2.2, ADA, and EAA standards, you are not just accessible – you are also likely to perform better in Google’s technical assessments.
