Machine learning automates much of a Google App campaign once it’s live. What’s one reason marketers should still be involved in the campaign after it’s launched?

• The marketer will still need to review search term and segmentation reports, to make appropriate manual adjustments.
• The strategy behind an App campaign will likely shift over time, meaning boundaries need to be set accordingly.
• The marketer will need to look for and resolve any campaign issues found within the notifications section of the account.
• An App campaign will request human input via questionnaires from time to time, to help steer its marketing objectives.

The correct answer is:

• The strategy behind an App campaign will likely shift over time, meaning boundaries need to be set accordingly.
