There are a number of ways and options available for you to check the Page speed of your website.
Google PageSpeed Insights
Google offers their own “PageSpeed Insights” tool, which helps you determine the PageSpeed of a website with a PageSpeed Score, a grading scale which can go from 0 to 100.

If you analyse a website with the PageSpeed Insights, you will receive concrete instructions for how you can improve your PageSpeed, in addition to the overall score.
Google Analytics
In Google Analytics you can check the average PageSpeed of a website, as well as other speed metrics.

Core Web Vitals
Core web vitals, a performance metric that will be used by Google as a ranking factor in 2021, are available in the SISTRIX toolbox.

SISTRIX Optimizer Lighthouse performance
With the Optimizer module you can also measure and track Core Web Vitals reported by our built-in Lighthouse performance tool. Not all figures refer to page load speed

Chrome Browser Lighthouse performance checking tool
The Lighthouse performance tool is also available as part of developer tools in the Google Chrome browser. To access this, use the Inspect menu option, or Ctrl+Shift+i


Within developer tools, which usually appears to the right of the web page within Chrome, you can find a menu marked Lighthouse. Within this you are able to specify the Performance category and the type of device that wish to emulate.
