To change a tracking pixel in any way, enter the relevant project in AudienceReport. From here click "Actions" in the top right corner, and then click "Edit campaign".
Now click "Tracking points" on the left.
From here you can rename the tracking pixel, or change the "function" of it.
Renaming a tracking pixel
To rename a tracking pixel, simply click "Actions" on the right side of the relevant tracking pixel, then click rename. From here just type in the wanted pixel name, and press "OK". Always remember to click the green "Save" button when you are finished making changes.
Changing the function of a tracking pixel
To change the function of a tracking pixel (i.e. from impression tracking to click tracking) click the pencil icon next to the pixel.
From here you can check the boxes for the relevant tracking. However, be aware that selecting an event doesn't mean it is automatically tracked. For each event, you need to implement a corresponding tracking pixel in your adverser. Make sure to click "Save" when you are finished making changes.
It can take up to 10 minutes for the changes to appear in your project, so don't worry if you can't see the new tracking pixel right away.
