An advertiser wants to maximize the total number of successful transactions while making sure they don't exceed a specific cost-per-acquisition (CPA) threshold. Which automated behavior does the algorithm prioritize under this specific bidding strategy?

With target CPA or a conversion-focused automated bid strategy, Display & Video 360 changes bids impression by impression based on the predicted chance that the impression will drive the chosen outcome. Google states that automated bid strategies optimize a line item’s bid based on the likelihood that an impression will lead to a conversion and whether that impression is available at an optimal price compared to the market. When the strategy is set to maximize conversions while prioritizing a target KPI, meeting the performance goal takes priority over simply spending the budget. That means the algorithm’s core behavior is real-time bid adjustment using predicted conversion likelihood, which is how it works toward the CPA threshold while still pursuing more conversions.
