How fast is your website?
We check your site with the Google PageSpeed engine (mobile view): a performance score, Core Web Vitals and a concrete list of what slows it down.
The measurement is run by Google PageSpeed Insights. We do not store the checked addresses. The test can take several seconds.
What does the test show?
- A 0-100 performance score by Google (mobile view).
- Core Web Vitals: LCP (largest element), CLS (layout shift) and more.
- Specific things that slow the site down most, with an estimated time saving.
