The Cost of Slow Page Load Speed
Studies show that a 1-second delay in page load time reduces conversions by up to 7%. For modern e-commerce stores, speed is not a technical vanity metric — it directly dictates revenue.
Core Web Vitals Breakdown
Google evaluates your website based on three primary metrics:
| Metric | Good Benchmark | What It Measures |
|---|---|---|
| LCP (Largest Contentful Paint) | Under 2.5s | Loading Speed |
| FID (First Input Delay) | Under 100ms | Interactivity |
| CLS (Cumulative Layout Shift) | Under 0.1 | Visual Stability |
Optimization Checklist for 2026
- Convert heavy PNG and JPEG images to WebP or AVIF formats
- Minify CSS and JavaScript bundles
- Use HTTP/2 and server-side page caching
- Implement responsive lazy loading for media below the fold
