Please also read the subsequent remarks concerning the filtering of double clicks and the amount of none-trackable interactions of people with Privacy protection (addons) to understand our price model.

To avoid the problems of click fraud and inadvertent double clicks, we use Google Analytics 4 with a data retention of 14 months to determine how many users have been referred. You only pay per users. In the example depicted below, you would pay for 146 users. These people have clicked 213 times.

However, please note that a few browsers block Google Analytics 4. This hidden traffic of up to 20% currently can be measured by using for example a link shortener or careful analysis of your logfiles using a specific landing page (see best practises PDF). We recommend that you use a neutral tool for all incoming paid traffic so the data and the costs are comparable. You can then also better estimate how much the advertising service provider's data deviates in your or his favor.
