To associate an Audience to a Line Item follow these steps:

1. Create or select a Line Item and open the Line Item configuration menu.
2. Scroll down to the ‘Audiences’ dropdown and choose the ‘Associate Segments’ button on the right-hand side.
3. Choose the red ‘Add New Group’ button on the right-hand side of the window. A box should appear with the words ‘drag and drop segments to add new group’.
4. Choose to target ‘Any’ or ‘All’ between groups. See the ‘Boolean Logic’ section below for an explanation of these functions.
5. Find the segments you wish to add on the left-hand side and drag them into the box on the right-hand side.
   • ‘Audiences’: Audiences created with a remarketing pixel under this Advertiser will appear here.
   • ‘Custom Audiences’: Custom Audiences can be created in the ‘Audiences’ tab and will automatically be available to all Advertisers in the seat. Certain custom Audiences will only be available to associate when the correct ‘Inventory Type’ is selected. For example, Lat/Long Audiences can only be used when ‘In-app’ or ‘Open’ is selected as the inventory type.
   • ‘Third-Party Audiences’: For Third-Party Audiences to appear here, open the ‘Audience’ tab and use the blue ‘Associate’ button to associate the selected Audience segment to the Advertiser.
   • ‘Onboarded Audiences’: For Onboarded Audiences to appear here, open the ‘Audience’ tab and use the blue ‘Associate’ button to associate the selected Audience segment to the Advertiser.
6. These Audiences can be ‘targeted’, or ‘anti-targeted’. To switch to ‘exclude’ or ‘anti-target’ an Audience, select the gray minus sign next to the name of the segment. When you click on the minus symbol it will change from gray to red, indicating that the Audience is now being ‘anti-targeted’. This Line Item will now serve to any user that is NOT in this Audience. In the example below, the Line will serve to anyone who is not in this segment of politically conservative users. If you are only using one Audience, there is no difference in the exclusion feature between ‘any’ and ‘all’. See the Boolean logic section below if you are using multiple Audience segments.
7. Select the red ‘Add New Segments’ button at the bottom of the window to save the changes and then submit or save the Line Item.
8. Add the average cost (CPM) for all associated segments to the Bid Data for the Line Item.
