What Is PageSpeed Insights and How It Impacts Your Website’s Performance
Use Cases
Google confirmed that page speed is a ranking factor. A better PSI score can lead to higher visibility in search results, especially on mobile.
Slow-loading pages frustrate users. PSI recommendations help eliminate performance bottlenecks that cause visitors to abandon your site.
Milliseconds matter. According to Google, as page load time goes from 1 to 3 seconds, bounce probability increases by 32%. PSI helps you stay fast.

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.
