How to use Facebook's campaign budget optimization to improve results
With the use of the CBO, Facebook automatically "concentrates its firepower" and allocates more budget to ad groups that generate more conversions. As the following image shows, after the less expensive optimization events of Ad Group A have all been achieved, the budget automatically flows to ad groups B and C, resulting in more conversions to the entire campaign.
Finally, a diagram is used to briefly summarize the characteristics and benefits of CBO.
In summary, with CBO, the system can move away from the budget limits of each ad group in the past, allowing the budget to flow flexibly between different ad groups and automatically "capture" the lowest-cost optimization events in real time. With the same budget, campaigns that use CBO are maximized by budget, resulting in more conversions and maximizing marketing effectiveness.
