The Unique User Reach report returns data in a bubble chart. Each bubble is sized in direct proportion to the number of unique users for your selected dimension. A larger bubble indicates greater reach than a smaller bubble.
The Unique User Reach report helps you find the advertiser, brand, campaign, creative, placement, or site that provides the broadest reach against your targeted users.
Keep in mind that:
The Unique User Reach report displays information only for users with Admin permission levels. Your Audience Manager consultant or Customer Care can provision your account with Admin permissions.
7-day and 30-day look-back periods are only available for Sunday.
