What's one way for marketers to save time while improving their optimization score?

Opting into applying recommendations automatically as they get surfaced is a direct way to save time and improve your optimization score. This feature allows Google Ads to implement suggested improvements without manual intervention, ensuring your account is consistently optimized according to best practices. "Opt-into applying your assets at the campaign level" is incorrect because assets are a component of ads, and while important, this action doesn't directly automate optimization score improvements across the entire account. "Select 'View all' for recommendations in a given category" is incorrect because viewing recommendations is a manual step, not an automation that saves time. "Select 'Apply all' in your negative keyword targeting" is incorrect because while applying negative keywords is a good practice, it's a specific, manual action for one aspect of optimization, not a broad automation for the entire score.
