How to Achieve a 100 PageSpeed Score in Next.js

Reading Time: 6 min | By Vansh

Welcome back to Vibe with Vansh! Fast websites rank higher on Google, keep users engaged, and convert better. But heavy images, unoptimized Web Fonts, and bloated JavaScript bundles can slow down your Next.js application.

Follow this step-by-step optimization workflow to hit perfect Core Web Vitals scorecards.

The Core Web Vitals Optimization Checklist

STEP 1

Leverage `next/image` for Automatic WebP Compression

Replace standard HTML <img> tags with Next.js's Image component to automatically serve responsive WebP/AVIF images, prevent layout shifts (CLS), and enable lazy loading.

STEP 2

Zero CLS with `next/font`

Self-host Google Fonts using next/font. It automatically inlines CSS at build time, eliminating render-blocking external font requests and layout shifts.

STEP 3

Optimize JavaScript Bundles & Script Loading

Use next/script with strategy props (like lazyOnload or afterInteractive) for analytics and third-party scripts to keep the main thread free.

Essential Metrics to Track

  • LCP (Largest Contentful Paint): Aim for under 2.5 seconds by optimizing hero images and server response times.
  • INP (Interaction to Next Paint): Keep under 200ms by minimizing heavy synchronous JavaScript execution.
  • CLS (Cumulative Layout Shift): Maintain a score below 0.1 by reserving layout space for dynamic elements.

Computer Science vs Information Technology: Which Tech Career Path Fits You Best? Author: Vibe with Vansh • Category: Tech Fundamentals If you are standing at the crossroads of starting a career in the tech industry, you’ve likely stumbled upon two massive domains: Computer Science (CS) and Information Technology (IT) . While many people use these terms interchangeably, they represent two fundamentally different mindsets, skill sets, and day-to-day career paths. Quick Takeaway: Think of Computer Science as building and designing the car engine, while Information Technology is focused on ensuring the fleet of cars runs smoothly on the road system. 1. What is Computer Science (CS)? Computer Science is rooted in theory, algorithms, and computational mathematics. It asks the core question: "How can we solve complex problems through code and efficient computational systems?" As a CS professiona...
