Which action should you take if your goal is to optimize display campaigns before increasing budgets?

To optimize display campaigns before increasing budgets, you should remove and replace low-performing assets. This action directly addresses underperforming elements, allowing you to improve campaign efficiency and return on ad spend without immediately spending more. By replacing weak assets with stronger ones, you enhance the overall quality and effectiveness of your ad creatives, which can lead to better engagement and conversions. Adding new assets multiple times per week might dilute performance tracking and doesn't specifically target underperforming elements. Pausing the campaign stops all optimization efforts. Replacing all assets at once is a drastic measure that prevents you from understanding which specific assets were underperforming and which were successful.
