You're the marketing manager for an online sporting goods store and have been tasked to optimize the company's display campaigns before increasing their budgets. What should you do to achieve this goal?

To optimize display campaigns before increasing budgets, you should remove and replace low-performing assets. This strategy allows you to systematically improve campaign effectiveness by eliminating creative elements that aren't resonating with your audience and introducing new ones with better potential. Replacing all assets at once is risky as it doesn't allow for iterative learning and could negatively impact performance if the new assets are worse. Pausing the campaign stops all progress and learning. Adding new assets multiple times per week without removing underperformers can dilute performance insights and make it harder to identify what's truly working.
