An advertiser wants to run an Awareness campaign targeting parents and users (over age 18), with different creative messaging. What are two advantages of using campaign budget optimization?

Campaign Budget Optimization (CBO) is a feature where the budget is set at the campaign level rather than the individual ad group level. This allows Pinterest’s algorithm to automatically and continuously distribute the budget to the best-performing ad groups in real-time. Better budget utilization: Instead of manually guessing how much to spend on "Parents" versus "Users 18+," CBO does the heavy lifting. If the "Parents" ad group is seeing significantly more engagement or cheaper reach on a particular day, the system will shift funds there automatically to ensure your money is working as hard as possible. Maximizes campaign outcome: By funneling more budget to the ad groups that are performing well, the campaign as a whole achieves a higher total volume of results (such as impressions or clicks) than it would if the budget were strictly locked into underperforming segments.
