FAQ Frequently Asked Questions

What metrics does PageSpeed Insights measure?

The tool measures Core Web Vitals including Largest Contentful Paint (LCP), First Input Delay (FID), Cumulative Layout Shift (CLS), plus other performance metrics like First Contentful Paint and Speed Index.

How often should I check my website's performance?

Check regularly, especially after making changes to your website. Monthly checks are good for monitoring, but test immediately after major updates, new feature deployments, or when you notice performance issues.

What's the difference between mobile and desktop scores?

Mobile and desktop scores reflect different device capabilities and network conditions. Mobile scores are typically lower due to slower processors and network connections, and Google prioritizes mobile performance for rankings.

How do these scores affect my SEO rankings?

Core Web Vitals are official Google ranking factors. Better performance scores can improve search rankings, while poor scores may negatively impact visibility. Page experience is increasingly important for SEO.

Can I track improvements over time?

While this tool provides point-in-time analysis, you can manually track scores over time or use Google Search Console for historical Core Web Vitals data to monitor your website's performance trends.
