PageSpeed and Core Web Vitals Checker

Run Google's mobile speed test on your homepage and get the key numbers and biggest savings in plain language.

Enter a domain only, no http:// needed. The test can take up to 40 seconds.

How this works

  1. We call Google's PageSpeed Insights service for your homepage on a simulated mid-range mobile phone.
  2. We show lab metrics (LCP, TBT, CLS) and, when available, real-visitor data from the Chrome UX Report.
  3. We list the largest time savings Google found, so you know where to start.

Frequently asked questions

Why does the test take up to 40 seconds?

Google loads and measures your page for real. Results are cached for 10 minutes.

Why is my score different each time?

Lab tests vary by a few points between runs because of server load and network conditions.

Which metric matters most?

Google's Core Web Vitals are LCP (loading), INP (responsiveness) and CLS (visual stability). Real-visitor data counts more than lab scores.

What causes slow WordPress sites?

Heavy page builders, unoptimised images, too many plugins and slow shared hosting are the usual causes.
