Final answer:
Option (D), Using Search Ads 360 efficiently means leveraging its automated bidding and optimization features for real-time optimization, as manual or infrequent optimizations are less effective in the dynamic digital advertising landscape.
Step-by-step explanation:
When using Search Ads 360 for optimizing advertising campaigns, it is usually most effective to leverage automated bidding and optimization features. These functions utilize machine learning to analyze data and optimize bids in real-time, which can lead to improved performance and efficiency over manual adjustments or simply relying on default settings.
To fully capitalize on Search Ads 360 capabilities, one should not choose 'Do not optimize' as it will not utilize the platform's full optimization potential. Optimizing manually every six months is not recommended because the digital advertising landscape changes rapidly and frequent adjustments are necessary to stay competitive. Trusting solely in default settings may result in missed opportunities for customization and optimization specific to your campaign's needs.
Therefore, the preferred approach would be to implement and monitor automated bidding strategies, making adjustments as necessary based on the campaign's performance analytics and market changes.
