Since Google replaced First Input Delay with INP (Interaction to Next Paint) in 2024, the bar for a fast, snappy site is higher than ever. The winners in 2026 aren't chasing a 100 Lighthouse score - they're obsessing over real-user metrics.
The three metrics that matter
- ✓LCP (Largest Contentful Paint) - target < 2.5s. Usually the hero image or headline
- ✓INP (Interaction to Next Paint) - target < 200ms. Every click, tap, and keypress
- ✓CLS (Cumulative Layout Shift) - target < 0.1. No jumping content
The quick wins
- ✓Serve hero images as WebP or AVIF, sized responsively with srcset
- ✓Preconnect and preload fonts, but only the weights you use
- ✓Defer or async every non-critical third-party script (chat, analytics, ads)
- ✓Ship less JavaScript - audit with Chrome DevTools coverage panel
- ✓Move heavy computations off the main thread with Web Workers
