What are three efficient ways for marketers to apply recommendations that impact optimisation score?

The correct options represent efficient ways to apply recommendations. Using 'Apply all' allows for quick implementation of all suggestions with a single click, saving time. Opting in to apply certain recommendations automatically ensures that improvements are made continuously without manual intervention, maintaining a high optimization score. Reviewing and applying individual recommendations within each category provides a structured approach, allowing marketers to prioritize and implement changes strategically based on their specific campaign goals, rather than sifting through an undifferentiated list. Reviewing recommendations under campaign settings is not the primary interface for applying them; recommendations are typically found in the "Recommendations" section. Applying individual recommendations in a Keyword report is too granular and doesn't encompass the full range of recommendations available.
