PageSpeed Insights (PSI) is a free tool from Google that analyzes your website's performance on both mobile and desktop devices. It provides a score from 0 to 100, along with practical suggestions to improve loading speed and user experience.

The tool evaluates your site using two main categories:

• Core Web Vitals: Metrics measuring real-world user experience (loading, interactivity, visual stability).
• Performance Metrics: Traditional speed measurements like First Contentful Paint and Time to Interactive.

Why does this matter? Faster websites rank higher in Google search results and keep visitors engaged. A slow site often leads to high bounce rates and lost conversions.

To use PageSpeed Insights:

1. Enter your website URL on the PSI webpage.
2. Review your performance score and diagnostic feedback.
3. Implement suggested optimizations (image compression, code minification, caching).

Regularly checking your PageSpeed score helps maintain optimal performance as your site evolves. Aim for a score above 90 for excellent performance, though improvements at any level benefit your visitors.
