Even though many of Performance Max's features are optimized via machine learning, some need to be added manually. Which of these features need to be added manually? Choose two.

Budget and ad creatives are features that must be added manually in Performance Max. You set your campaign budget to control spending, and you upload ad creatives (images, videos, headlines, descriptions) to provide the assets Performance Max uses to generate ads. Bids are automatically managed by Performance Max based on your conversion goals and value rules, though you can set target ROAS or CPA. Creative combinations are automatically generated by Performance Max using the assets you provide. Ad placements are automatically determined by Performance Max across Google's inventory to find the best opportunities to meet your goals.
