Questions People Ask
Honest answers about how this works.
How is the performance score calculated?
The score is based on a weighted average of page weight, the number of requests, and presence of critical performance tags. A score above 80 is considered excellent.
Does this measure Core Web Vitals?
This tool focuses on asset optimization and initial response metrics. For full Core Web Vitals (LCP, CLS), we recommend using Google PageSpeed Insights alongside this tool.
Why is my speed different here than on mobile?
Honestly? Mobile devices often have slower CPUs and more restrictive networks. We simulate standard desktop and mobile constraints to give you a balanced view of performance.
