Monitor automaticallyCommon questions.
Is this website speed test really free?
Yes. Run as many manual speed tests as you like at no cost. AuditJet only charges for automated 24/7 monitoring, alerts, and continuous reporting.
What engine does AuditJet's speed test use?
AuditJet uses Google's Lighthouse and PageSpeed Insights engine — the same infrastructure behind Google's Core Web Vitals measurements and search ranking signals — enhanced with proprietary revenue impact modeling.
Do I need to sign up to run a website speed test?
No account is required to run a free speed test. Creating an account lets you save results, track improvements over time, and set up automated monitoring and alerts.
Why does my website speed test score vary between runs?
Lighthouse scores fluctuate because synthetic tests are sensitive to server response variability, network conditions at the time of the scan, and background processes on the test machine. A single run can differ by 5–10 points from the previous one. AuditJet addresses this by running multiple samples per scan and reporting a stabilized median score, and by tracking score trends over time so you can distinguish genuine regressions from natural variance.
How does mobile speed testing differ from desktop testing?
AuditJet's mobile speed test applies 4G network throttling and mid-tier CPU slowdown to simulate the device profile that represents the majority of global web traffic. Desktop testing uses no network throttling and full CPU speed, which produces consistently higher scores. Because Google uses mobile-first indexing, AuditJet weights mobile results as the primary performance signal when calculating your revenue impact estimate.
What's the difference between a website speed test and website performance monitoring?
A speed test is a point-in-time measurement: you run it, you get a report, and it captures how the page performs at that exact moment. Performance monitoring is continuous — AuditJet scans your pages on a recurring schedule (hourly or daily), stores historical data for up to a year, and sends alerts the moment a metric crosses a threshold. Speed tests are useful for diagnosing a known issue; monitoring catches regressions before they affect traffic or revenue.
