Why Seconds Equal Sales
A one-second delay in page load time can reduce conversions by up to 20%. Users expect web pages to load instantly. If a visitor has to wait on a blank white loader, they will tap back and click on a competitor's link.
Understanding the Three Core Metrics
1. Largest Contentful Paint (LCP): Measures how fast the main content loads (Target: under 2.5s). 2. Cumulative Layout Shift (CLS): Measures page visual stability (Target: score under 0.1, meaning text doesn't shift around). 3. Interaction to Next Paint (INP): Measures page responsiveness to clicks or taps (Target: under 200ms).
