How can I check my website’s PageSpeed?

There are a number of ways and options available for you to check the PageSpeed 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.

The website zappos.com achieves a desktop PageSpeed score of 79 points, which still has room for improvements

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.

You can find the report in the category “content” under “website speed.”

When using the key values from Google Analytics, it is important keep a few things in mind. Google will take redirects into account when they calculate the average page load time and they will only calculate the website-speed for users whose browser is able to support the HTML5-interface “Navigation Timing” or those who have installed the Google Toolbar. This can be the reason why these key values may fluctuate or why they may be different compared to other evaluations

SISTRIX Optimizer

With the Optimizer module you can monitor a website in 3 hour intervals and analyse the server performance in our waterfall-diagram.
