Lazy Loading Images Best Practices 2026
Use this pillar to improve Core Web Vitals while preserving crawlability and image SEO value.
Use native lazy loading first
Apply loading="lazy" on below-the-fold images. Keep above-the-fold hero images eager.
Protect LCP elements
Do not lazy load your primary hero image if it contributes to LCP. Preload critical assets where needed.
Maintain image discoverability
Use descriptive file names, alt text, and include important images in image sitemap feeds.
Serve modern formats wisely
Use WebP/AVIF where possible with proper fallbacks and compressed source dimensions.
Measure impact
Track LCP, CLS, and engagement metrics before and after deployment to validate gains.
