An automated bidding strategy to help get the most conversions for your campaigns while spending your budget.
The target cost-per-action (CPA) option. This is the average amount that you would like to spend per conversion action. If set, the bid strategy will get as many conversions as possible at or below the target cost-per-action. If the target CPA is not set, the bid strategy will aim to achieve the lowest possible CPA given the budget.
