Next.js Performance Checklist for High-Converting Websites

Performance isn’t just a technical metric — it’s revenue. Faster pages keep users engaged and reduce bounce, especially on mobile networks.

Start with measuring: Lighthouse, WebPageTest, and real-user metrics (RUM). You can’t improve what you don’t track.

Optimize images, reduce JS bundles with dynamic imports, and keep critical UI server-rendered when possible.

Finally, watch your third-party scripts. Marketing tags can silently destroy your Core Web Vitals if left unchecked.
