To optimize display campaigns before increasing the budget for an online sporting goods store, which action should be taken?

Removing and replacing low-performing assets is a strategic action that directly addresses the overall effectiveness and efficiency of the display campaigns. By identifying which ads, images, or messaging are underperforming, you can enhance the overall performance of the campaign. This approach allows for reallocating resources toward higher-performing assets, which could lead to better engagement and conversion rates.

Improving the quality of your ad materials before increasing the budget ensures that more of the additional spend goes toward effective ads, rather than amplifying less effective ones. Over time, this can lead to sustainable performance improvements. It's a proactive way to fine-tune your marketing efforts, aligning them with your goals for growth and return on investment.
