AdRoll does not have a minimum spend requirement. However, in order to properly optimize your campaign, you will need to allow a minimum daily budget of $3. Your budget represents the maximum authorized spend per week. Spend is influenced by the following factors:
- The number of users you're targeting (size of your audience): Targeting large user lists increases your advertising reach and helps you get in front of more potential customers.
Variety of ad sizes: Uploading multiple ad units to your web campaigns will secure premium inventory space. AdRoll recommends a minimum of three different ad sizes (300×250, 728×90, and 160×600 are most popular).
The amount you bid for each ad placement: AdRoll has algorithms that evaluate each user based on their level of intent, the inventory available, and seasonal factors.
