Technical SEO Checklist

Core Web Vitals (2026 Targets)

LCP (Largest Contentful Paint) < 2.5s
INP (Interaction to Next Paint) < 200ms   ← replaced FID
CLS (Cumulative Layout Shift)  < 0.1
TTFB (Time to First Byte)      < 600ms

INP Optimization (the new critical metric):

// INP is degraded by long tasks blocking the main thread
// Solution: Use React's useTransition to defer non-critical updates
import { useTransition } from 'react';

function SearchInput() {
  const [isPending, startTransition] = useTransition();

  const handleChange = (e: React.ChangeEvent<HTMLInputElement>) => {
    startTransition(() => {
      // Defer the expensive filtering to not block INP
      setFilteredResults(filterData(e.target.value));
    });
  };
  return <input onChange={handleChange} />;
}
