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

The selected options are correct because they represent the three primary levels of efficiency provided by the Google Ads interface to help marketers quickly bridge the gap between their current setup and a 100% optimization score. Using "Apply all" allows for the most rapid improvement by implementing every suggested best practice across the account with a single click, while reviewing and applying individual recommendations within each category (such as Bidding, Keywords, or Ads) offers a balanced approach of efficiency and manual oversight. Finally, choosing to opt in to apply certain recommendations automatically creates the highest level of long-term efficiency, as it enables Google’s AI to proactively maintain account health and performance standards without requiring constant manual intervention from the marketer.
