You can also create tags for multiple ad units; just click “new ad unit” and then repeat the process. However, as we know that some values are normally used repeatedly across all adu units, you can perform bulk operations by clicking on “show global settings”. Here you can set the ad container and load method, and whatever you set here will be applied to all ad units you have specified below, as long as they are also set to “inherit global settings”. Here you can also specify segments, if there are specific user segments you would like to target with these ad units.
