When editing your Easy Affiliate > Creatives. You can assign each creative to a Campaign. Think of Campaigns as a way to categorize or organize your banner ads and text links.
Campaigns aren't currently used on the Affiliate's Dashboard (though we hope to support this soon), but for now, you as the Administrator can and should use them to organize your creatives, and make your life easier.
To filter your creatives by a particular Campaign, click the number in the “Count” column shown in the image above.
