What is the minimum lifetime budget for a Sponsored Brands campaign?

The correct answer is "$100 USD" because the minimum lifetime budget required for a Sponsored Brands campaign on Amazon is $100 USD. This budget is the total amount that an advertiser is willing to spend over the entire duration of the campaign. The lifetime budget allows Amazon to optimize the delivery of ads based on the campaign's duration and goals. It is designed for advertisers who want to set a fixed budget for their entire campaign period rather than a daily budget. While daily budgets can be set as low as $1 USD for Sponsored Products, Sponsored Brands campaigns require a higher minimum lifetime budget to ensure effective campaign management and reach.
