Which campaign optimization strategies should you take when your PLA campaigns have high spend-through but a low ROAS? Select all that apply.

The selected answer options are correct because when a PLA (Product Listing Ad) campaign has high spend-through but a low ROAS, the primary focus should be on improving the efficiency of ad spend and ensuring that the campaign delivers better returns. Decreasing the bid is an effective strategy to reduce spend and help optimize the campaign’s cost structure. By lowering the bid, you can manage the budget more effectively and avoid overspending on less profitable clicks, which could help improve ROAS over time. Additionally, removing low performing targets is another crucial step. By analyzing which product categories, keywords, or audience segments are not generating the desired return, you can eliminate those underperforming elements to focus the campaign’s budget on more effective areas. This helps to improve the overall performance of the campaign by allocating resources to the most profitable targets, ultimately improving ROAS. While adding targets or increasing the bid could potentially lead to more exposure, these actions would likely increase costs further without addressing the low ROAS, making them less effective for this particular scenario.
