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?
- Increasing the bid for every available impression regardless of user intent
- Adjusting bid prices in real time based on the predicted likelihood of a conversion
- Prioritizing the lowest-cost inventory available across all open exchanges
- Capping the total number of impressions served to a single user per hour
Explanation
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.

Why the other options are incorrect
Increasing the bid for every available impression regardless of user intent is incorrect because automated bid strategies evaluate predicted outcome likelihood and market price rather than raising bids universally. Google Help
Capping the total number of impressions served to a single user per hour is incorrect because that is a frequency cap control, not the bidding behavior used to optimize toward conversions at a target CPA. Google Help
Prioritizing the lowest-cost inventory available across all open exchanges is incorrect because the system optimizes for conversion probability and optimal price, not for cheapest inventory alone. Google Help
