Add a Geoframe or set of Geoframes to an existing Audience in the library
Create the new Geoframe(s) or find them in the library
Select the Geoframe(s) and create a new Geoframe Audience
Merge the original Geoframe Audience with the new Geoframe Audience you just created
Add Geoframe(s) to an audience that is already on a publish schedule
Create a second audience (see steps above) that includes the additional Geoframe(s), and then publish the new audience on the same schedule as the original audience. Alternatively, you can merge the two audiences together and set up a new publishing schedule, while cancelling the original publish schedule.
Add Geoframe(s) to an audience to generate combined Visual Reports (Insight, Demographic, Heatmap)
Use steps in first item above to create a new Geoframe audience with the new location(s) and merge the audiences together. Then, click "Generate/Share Reports" by clicking the 3 dot "action" menu to the right of the Audience name.
Execute manual analysis (i.e. Excel)
Create a new Geoframe audience or a merged audience, and then process the specific downloads you are looking to perform analysis on. See this article for available .csv downloads.
To use in Attribution Reporting
Multiple Geoframe audiences can be used as either the "Target" or the "Destination" Audience in the Attribution Report. Create a new audience for the Geoframe(s) you'd like to add in the reporting and merge with the original per the steps above, or create a new audience with the location(s) you want to add to the Attribution Report and add both as either the "Target" or "Destinations" as you set up your report.
