Page Speed Test

Bulk Page Speed Test

With the Bulk Page Speed Test you can automatically determine the websites speed for a large number of pages. A high Page Speed not only ensures more satisfied visitors, but has also become a ranking factor on Google. With our tool you can find slow subpages on your site or you can compare your site with those of your competitors.

How to Use

Our Page Speed test offers 3 different modes:

Crawl website
You set the start URL and we crawl the web page to find more URLs. Crawling is limited to 60s and 500 URLs.

URL List
You send a list of URLs for which we then determine the Page Speed.

You define a keyword for which we determine the Top 50 results at We then determine the Page Speed for each URL.

You can also choose whether the Page Speed should be determined from the point of view of a mobile device (mobile) or a desktop computer (desktop).


The metrics correspond exactly to the metrics of Google PageSpeed Insights or the Lighthouse Performance-Tool. In the following we introduce the different metrics to you.



The score gives a summary of the website speed on a scale of 0-100. Values above 90 are considered fast, between 50 and 90 a page is considered average and below 50 a page is considered slow. more Information


Time To First Byte (TTFB)

The Time To First Byte indicates how long a browser must wait until it has received the first byte of a page. This metric gives an indication of how long the server takes to deliver an answer. The value should be less than 600ms. more Information


First Contentful Paint (FCP)

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. more Information


Largest Contentful Paint (LCP)

The Largest Contentful Paint indicates the time when the browser rendered the largest visible element. This is the point in time at which the main content of the page was most likely loaded. more Information


Cumulative Layout Shift (CLS)

Cumulative Layout Shift measures the sum of all layout shifts that occur during the lifetime of the page. A layout shift occurs whenever a visible element changes position from one frame to the next. more Information


Time To Interactive (TTI)

Time To Interactive indicates the time at which the user can interact with the site. In concrete terms, this means that the browser already displays useful content (First Contentful Paint) and reacts to user input within 50ms. more Information



The metric Size indicates the combined size of all resources (HTML, JS, images, ..) of the website. The smaller the size, the less data has to be transferred. This has a big influence on the total loading time. more Information
