FAQ

How this task behaves.

  • 01

    Can the AI change my actual ad spend in Meta or Google?

    No. The AI only reads your data and provides analysis. It cannot execute changes to your live ad campaigns.

  • 02

    Does the AI delete any of my marketing data?

    No. The AI has read-only access to the data it needs to perform these calculations.

  • 03

    What data do I need to provide for a payback calculation?

    You need to provide your CAC and your LTV metrics for the AI to run the math.

  • 04

    Can it identify diminishing returns for specific sub-campaigns?

    Yes, as long as your data is segmented by those specific campaigns in your connected tools.

  • 05

    Will the AI automatically pause my ads when CAC gets too high?

    No. The AI identifies the problem and alerts you, but you must manually adjust your budget in your ad manager.
