What is Google PageSpeed Insights?

Google PageSpeed Insights (PSI) is a free tool by Google that analyzes the performance of your web pages on both mobile and desktop devices. It gives you a score from 0 to 100 and provides specific recommendations to improve your page loading speed.

PageSpeed scores directly impact your Google search rankings. Since 2021, Google uses Core Web Vitals as a ranking factor — meaning slow websites rank lower in search results.

Understanding PageSpeed Score Ranges

0-49
Poor
Serious performance issues. Urgent fixes needed.

90-100
Good
Excellent performance. Keep maintaining it.

Core Web Vitals Explained

Core Web Vitals are three specific metrics Google uses to measure user experience on web pages:

LCP — Largest Contentful Paint
Measures how long it takes for the largest content element (image or text block) to load on screen.
Good: Under 2.5 seconds
FID / INP — Interaction to Next Paint
Measures how quickly your page responds when a user clicks a button or interacts with the page.
Good: Under 200 milliseconds
CLS — Cumulative Layout Shift
Measures how much page elements shift or move while the page is loading — which is annoying for users.
Good: Under 0.1

Top Ways to Improve Your PageSpeed Score

Here are the most impactful fixes for improving page speed:

1
Compress and optimize images
Use WebP format instead of JPG/PNG. Compress images before uploading. Use lazy loading for images below the fold.
2
Minify CSS, JavaScript, and HTML
Remove unnecessary whitespace and comments from code files. Use build tools like Vite or Webpack to minify automatically.
3
Use a Content Delivery Network (CDN)
CDNs serve your files from servers closest to the user. Cloudflare offers a free CDN that significantly improves loading times globally.
4
Remove unused CSS and JavaScript
Use Chrome DevTools Coverage tool to find unused code. Remove plugins or scripts that are not actively being used.
5
Enable browser caching
Set cache headers so returning visitors load your site faster. Static assets like images and CSS should be cached for at least 1 year.
