How Is The DebugBear Page Speed Test Different?
More accurate data than Page Speed Insights
PageSpeed Insights, the Google site speed test, collects lab data by simulating a slower network. However, this can lead to inaccurate metrics being reported, so DebugBear collects data on a real throttled connection.
More in-depth reporting than Pingdom
Unlike Pingdom, DebugBear provides detailed debug data you can use to optimize your site.
Real-user metrics you won't find in GTmetrix
GTmetrix is a great lab testing tool, but doesn't surface the Google metrics that actually determine how well your website ranks.
Unique Performance Reporting For Your Web Page
Break down the Largest Contentful Paint metric
Check the different LCP subparts that make up your overall Largest Contentful Paint score.
Page Load Time Analysis
Analyze your page load time to see what requests block rendering or delay an LCP image.
Lighthouse audits included
Every result includes a full Google Lighthouse report, with the Performance score and all audits. Our website speed test runs Lighthouse on a real throttled connection rather than simulated throttling, so the scores reflect what visitors actually get.
Desktop And Mobile Website Speed Test
Page load time depends on network speed
The same website will load quickly on a low-latency and high-bandwidth connection and be slow on an unreliable mobile network.
Viewport size impacts web vitals metrics
Visitors can see different parts of the page depending on their screen size. Cumulative Layout Shift is often worse on desktop than on mobile.
CPU power determines web performance
A less powerful processor will result in worse Total Blocking Time and poorer interaction responsiveness.
