Which two things are essential for a Google App campaign to run smoothly and successfully? (Choose two)

For a Google App campaign to run smoothly and successfully, Data and Time are essential. Google App campaigns leverage machine learning to optimize performance. This machine learning requires a significant amount of data (e.g., conversion events, user behavior) to learn and make informed decisions about who to target and where to place ads. Without sufficient data, the system cannot effectively optimize. Similarly, time is crucial because the machine learning algorithms need an adequate learning period to process the data, identify patterns, and refine their strategies. Rushing the learning phase or making frequent, drastic changes prevents the system from reaching optimal performance. HTML5 assets are a type of creative asset, but not essential for the campaign to run, as other asset types exist. Bid changes are a lever for optimization, but not a foundational element for the campaign's operation itself.
