PageSpeed Insights

PageSpeed Insights↗ (PSI) is a free tool from Google that analyses your web pages on both mobile and desktop devices. It's an essential resource for developers, SEO specialists, and site owners who want to improve user experience and search rankings.

The Performance Score is a weighted average of several Lighthouse metrics, giving you a snapshot of your page's technical performance on a scale of 0–100:

Score	Rating	What it means
90 – 100	Good	The page is well-optimised and meets modern standards.
50 – 89	Needs improvement	There are noticeable bottlenecks.
0 – 49	Poor	Significant issues are likely driving users away.

This score is primarily driven by Core Web Vitals — the specific metrics Google uses to measure real-world user experience.
