PageSpeed Insights: Optimize Your Website Speed Like a Pro
Website speed isn’t just a tech detail—it’s a major factor that affects user experience, SEO rankings, and even conversion rates. A slow site can lead to lost traffic, higher bounce rates, and lower visibility in Google search results.
That’s why Google’s PageSpeed Insights tool is essential for anyone with a website. Whether you're a business owner, web developer, SEO specialist, or blogger, this free tool helps you test and improve your website's performance.
In this guide, you’ll learn how to use PageSpeed Insights, what the scores mean, how to improve them, and why they matter for both desktop and mobile users.
🌐 What is PageSpeed Insights?
PageSpeed Insights (PSI) is a free performance analysis tool by Google that measures how fast your web pages load and how well they perform, both on desktop and mobile devices.
It provides a detailed report that includes:
-
Speed score (0–100)
-
Core Web Vitals analysis
-
Page load metrics
-
Opportunities for improvement
-
Diagnostics and passed audits
You can access it here: https://pagespeed.web.dev
It uses real-world user data from Chrome (Field Data) and simulated lab testing to provide an overall performance snapshot.
🧪 How PageSpeed Insights Works
When you enter your URL into PageSpeed Insights, it runs a full audit using Lighthouse, a tool built into Chrome. It tests the website for:
-
Performance
-
Accessibility
-
Best practices
-
SEO
-
Progressive Web App readiness (PWA)
But the main focus of PageSpeed Insights is Performance, which includes key metrics like:
✅ Core Web Vitals:
-
Largest Contentful Paint (LCP) – Measures loading performance
-
First Input Delay (FID) – Measures interactivity (soon replaced by INP)
-
Cumulative Layout Shift (CLS) – Measures visual stability
🎯 Why Page Speed Matters for SEO
Site speed affects SEO in three big ways:
✅ 1. Google Ranking Factor
Google confirmed that page speed is a ranking factor for both desktop and mobile searches.
✅ 2. User Experience
Fast-loading pages reduce bounce rates and increase engagement. A delay of just 1 second can reduce conversions by 7%.
✅ 3. Mobile Optimization
With mobile-first indexing, mobile page performance is more important than ever for search rankings.

Step 3: Review Core Web Vitals
