Example
In this example, you can see that the share of different operating systems in overall traffic is higher for mobile OS, such as Android or iOS. But when it comes to the completion of the goal, a significant percentage of visits come from the devices with Windows.
The higher share of goal completions from Windows devices reflects the fact that desktop devices account for a significant share of selected Goal visits, as presented earlier.
