Betty’s manager is wondering why she needs to spend time on her new Google App campaign, since machine learning helps to automate a signiﬁcant amount of the campaign. What are three things Betty can do to guide the campaign? (Choose three.)

Make adjustments to the campaign in reaction to hourly ﬂuctuations in performance.
Create helpful boundaries for the system to work within, by setting a thoughtful bid and budget.
Build a library of diﬀerent ad assets, with the intention swapping them entirely on a weekly basis.
Provide the system with ample, meaningful data and the time to process it.
Keep an eye on strategy and objectives, evolving them over time as needed.
