PageSpeed Insights is a free tool provided by Google that analyzes a webpage’s loading performance on both mobile and desktop, providing a numerical score along with specific, actionable recommendations for improvement, based partly on real-world Core Web Vitals field data.
Unlike some third-party speed testing tools, PageSpeed Insights incorporates actual field data from real Chrome users when available, offering a more accurate reflection of genuine user experience rather than a purely simulated lab test.
Since Google uses Core Web Vitals as a ranking signal, regularly checking PageSpeed Insights and addressing its recommendations is a practical, direct way to support both technical SEO performance and user experience.
