What is the minimum daily budget multiplier when targeting CPA?

• A. 5
• B. 8
• C. 10
• D. 12

Answer: (C)

When you use Target CPA bidding, the system needs enough data to learn and optimize toward that target. Setting the daily budget to at least ten times the target CPA provides enough conversion data for reliable bidding adjustments and faster convergence to the desired CPA. For example, if your target CPA is $10, a daily budget around $100 helps the algorithm learn effectively. A smaller multiplier like five or eight can limit data and slow learning, while twelve is simply higher than the minimum and not required.
