Machine learning models are the basis for much of Performance Max's feature-optimization. Which three features still need to be added manually? Choose two.

Performance Max leverages machine learning to optimize many campaign aspects, but certain elements still require manual input. Ad creatives (headlines, descriptions, images, videos) are manually provided by the advertiser. While Performance Max will intelligently combine and serve these assets, the core creative components themselves must be uploaded. Similarly, the campaign budget is a manual setting determined by the advertiser to control spending. Performance Max will then optimize within that budget. Ad placements and bids are largely automated by Performance Max's machine learning, and creative combinations are dynamically generated from the provided assets, not manually added as a whole.
