Page Speed Test

With the EXPERTE.com Bulk Page Speed Test, you can automatically determine the speed and Core Web Vitals for your site. A high page speed not only ensures more satisfied visitors but has also become a ranking factor on Google. With our tool, you can determine which subpages are slow on your site or compare it with those of your competitors.

You can use our Page Speed Test in three different ways:

You can also select whether page speed should be determined for mobile devices or desktop computers.

The metrics used correspond to those of Google PageSpeed Insights or the Lighthouse Performance-Tool. Below, we'll introduce the different criteria used:

This rates website speed from 0-100. Values above 90 are considered fast, those between 50 and 90 are average, whereas a speed below 50 is considered slow. Click here for more information.

Time To First Byte indicates how long a browser must wait to receive the first byte of a page. TTFB basically shows how long the server needs to deliver an answer. This value should be less than 600ms. Click here for more information.

The First Contentful Paint specifies the time at which the browser displays a part of the website for the first time. This is an important milestone as it shows the user that the website is actually loading. Click here for more information.

The Largest Contentful Paint indicates the time when the browser rendered the largest visible element. This is the point in time by which the main content of a page is most likely to be loaded. Click here for more information.

Cumulative Layout Shift measures the sum of all layout shifts that occur over a page's lifetime. A layout shift happens whenever a visible element changes position from one frame to the next. Click here for more information.

The Total Blocking Time measures the time after the First Contentful Paint during which the web page is blocked and therefore does not respond to user input. The Total Blocking Time is very similar to the First Input Delay, but in contrast, it can be determined automatically. Click here for more information.

This indicates the combined size of all site resources (HTML, JS, images, etc.). The smaller this is, the less data needs to be transferred. Size has a significant impact on the total loading time. Click here for more information.
