To reduce high ACOS, optimize by decreasing bids on the affected products, which will lower spend for those ads and improve campaign profitability.
- Increase bids on these products if they have high sales
- Make no bid adjustments as they will have no effect on this
- Decrease bids on these products to help reduce ACOS
The correct answer is: Decrease bids on these products to help reduce ACOS
Explanation: When your campaign reports show products with high advertising cost of sales (ACOS), you should decrease bids on these products to help reduce ACOS. Lowering the bids cuts ad spend for those underperforming keywords or products, making your campaigns more efficient and improving overall return on investment (ROI).
