How this tool works
This mobile speed test separates controlled Lighthouse lab measurements from real-user CrUX data. Use the findings to identify slow rendering, blocking scripts, oversized images, caching gaps and other practical improvements.

Mobile Website Speed Test
Test the mobile performance of any public webpage. Get real Lighthouse metrics, available CrUX field data and prioritized opportunities.
Understand your results
A performance score summarizes the Lighthouse audit. LCP, CLS, FCP, Speed Index, TBT and server response data explain where time is spent. INP is only shown when valid field data exists.
Practical optimization tips
Start with high-impact opportunities, then retest the same URL after changes. Optimize server response, critical resources, images, fonts and long-running JavaScript without sacrificing the user experience.
Frequently asked questions
Is this an official Google or AI score?
No. PageSpeed metrics come from Google where applicable; QuickWebify SEO and readiness scores are transparent technical indications.
Do you store the URL?
Results are cached temporarily to prevent duplicate load. No registration or personal details are required.
Can this replace a full audit?
No. It is a focused first check. A full audit considers templates, multiple URLs, analytics, business goals and implementation details.
