About Pagespeed Insights Checker
What is Pagespeed Insights Checker?
The Pagespeed Insights Checker by seochecker.tools allows you to test your website’s performance and Core Web Vitals using Google’s Pagespeed API. It provides mobile and desktop speed scores, suggestions for improvement, and key metrics like Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS), and First Input Delay (FID).
Website speed is a direct ranking factor in Google’s algorithm. Slow-loading sites lead to higher bounce rates, lower rankings, and reduced conversions. With this tool, you get real-time speed audits and actionable SEO fixes in one click.
