With the help of Google Adsense (conversion tracking), Google and we can see which Google ad a user has clicked on and which of our pages the user was redirected to. In combination with the information obtained through cookies, this serves to create statistics. We thus learn through these statistics the number of users who clicked on the ad placed on Google and were redirected to one of our websites.

If we make major changes to our website, we initially test the improvements to the design or functionality with only a portion of our visitors. In order to recognize this group of users on their next visit, we use services and cookies from Google Optimize.

So that we still know information about your preferred language, the first page you visited with us or your cookie preferences on your next visit, we store them, but anonymously. Your preferences are also not forwarded to third-party providers.
