Does the tool recommend increasing ad spend?
No, the tool doesn’t recommend increasing or decreasing the budget: it simply shows different reallocation scenarios and predicts how selecting one would affect the performance of each displayed metric.
Why is the budget reduced for campaigns with a relatively low CPA?
This can happen if:
There’s a significant gap between the Avg. Daily Spend and Budget amount. This means the associated campaign is not spending the full budget amount in the first place.
The associated campaign doesn’t have the potential to keep getting more conv/clicks/conv.value based on historical performance.
Some of the campaigns associated with the budget are not active.
Is Performance Max supported?
You can manually change the daily budget amount, but the system won’t suggest reallocation from or to Performance Max campaigns. The reason is Google doesn’t share impression share lost due to budget data.
Are Facebook budgets Supported?
No, Facebook budgets are not included in the system-generated reallocation suggestions at the moment. You can still edit the daily budgets manually.
