No universal CBO vs ABO split at $50,000 a month
There is no universal percentage for splitting about $50,000 a month on Meta. Ad sets on different bid strategies cannot share one Advantage+ campaign budget, the control buyers still call CBO. Where they can share it, size a fair test from the week's purchases. Meta, as Adwize reports, also points to an ad set budget when audience sizes differ a lot.
