About Page Speed Checker
Page Speed Checker is used to get a quick performance score and Core Web Vitals summary for any URL using the Google PageSpeed Insights API. It queries the PageSpeed Insights API for the target URL and displays LCP, FID/INP, CLS scores alongside the overall performance rating. Focus on LCP (Largest Contentful Paint) and CLS (Cumulative Layout Shift) first — these two metrics have the biggest impact on Google's Core Web Vitals ranking signal. Page Speed Checker runs free in your browser at abovetool.com — no signup required.
