Website speed test

Your page loaded by Google in a real browser — once on a throttled phone, once on a desktop — with the performance scores, Core Web Vitals and the fixes that save the most seconds.

About a minute. No signup for the summary.

What this check looks at

SpeedHow fast your server answers, and Google PageSpeed Insights loading the page on a throttled mid-range phone and on a desktop: both scores, Core Web Vitals and the biggest wins in seconds saved.
The page answersStatus code, redirects and how long the server takes to send the first byte.
HTML weightHow heavy the page is before images and scripts — a bloated page is slow on every phone.
HTTPSWhether the site runs on HTTPS rather than plain, readable HTTP.
CertificateWhether the TLS certificate is valid and how many days it has left.
Mobile viewportThe tag without which phones render the desktop page, tiny.

Plus the rest of the 30+ checks — every scan runs all of them.

Why it matters

The phone score is the one that matters: most visitors come on a phone, and Google ranks by the mobile version. We run both side by side so you see the gap.

While Google measures, the same scan checks the server response, the page weight and 30 other things — so a slow page and a missing privacy policy show up in one report.

Questions

Where do the speed numbers come from?

From Google PageSpeed Insights (Lighthouse), run on a simulated mid-range phone over a throttled connection and on a desktop.

Why is my phone score so much lower?

The phone test uses a slower processor and network, like most real visitors have. Heavy JavaScript and large images hurt it most.

Is the speed test free?

Yes, no signup needed for the summary.
