What Is PageSpeed Insights and How It Impacts Your Website’s Performance
PageSpeed Insights (PSI) is a diagnostic tool from Google that evaluates the performance of a web page on both mobile and desktop devices. It scores your page from 0 to 100 based on various performance metrics, including Core Web Vitals like Largest Contentful Paint (LCP) and Cumulative Layout Shift (CLS). PSI doesn’t just give you a score; it offers clear, prioritized recommendations that developers and marketers can use to make their sites faster, smoother, and more user-friendly. A higher PSI score typically correlates with better SEO rankings, lower bounce rates, and higher conversion rates—especially on mobile.

Frequently Asked Questions
Is PageSpeed Insights accurate?
Yes, but it's important to understand that PSI uses both lab data (simulated testing) and field data (real user experience). Use both for a complete picture.
What is a good PageSpeed Insights score?
A score of 90 or above is considered good. 50–89 is average, and below 50 means your page needs significant performance improvements.
Does PSI affect Google ranking directly?
Page speed is a ranking factor, particularly on mobile. While the PSI score isn’t used directly, its metrics like LCP and CLS are part of Core Web Vitals, which Google does consider.
How often should I check my PageSpeed Insights?
Absolutely. Many PSI tips—like image compression, lazy loading, and using a CDN—can be implemented with easy-to-use plugins or your CMS settings.
Can non-developers use the suggestions in PSI?
Start with the high-impact recommendations: optimize images, reduce JavaScript, enable caching, and improve server response time. PSI provides prioritized tasks to guide you.
