How to Reduce ACoS and Increase ROAS on Amazon
What is ACoS and ROAS?
ACoS (Advertising Cost of Sales)
ACoS shows how much you spend on ads to generate sales.
👉 Lower ACoS = Better profitability
ROAS (Return on Ad Spend)
ROAS shows how much revenue you earn for every rupee spent on ads.
👉 Higher ROAS = Better performance
Why ACoS is High (Common Reasons)
• Targeting irrelevant keywords
• Poor product listing quality
• High competition bidding
• Low conversion rates
• Lack of campaign optimization
👉 Fixing these areas is key to improving performance
Step-by-Step: How to Reduce ACoS on Amazon
1.Optimize Your Product Listing First
Before running ads, your listing must convert.
Focus on:
• SEO-optimized title
• High-quality images
• Clear bullet points
• Strong product description
👉 Better conversion rate = Lower ACoS
2.Target High-Intent Keywords
Not all keywords are equal.
Use:
• Long-tail keywords
• Buyer-intent search terms
• Relevant product-specific keywords
👉 This reduces wasted ad spend
3.Use Negative Keywords
Block irrelevant searches that don’t convert.
👉 Prevents unnecessary spending and improves targeting
4.Optimize Bids Regularly
Avoid overbidding on low-performing keywords.
👉 Adjust bids based on performance data
5.Structure Campaigns Properly
Use a mix of:
• Automatic campaigns (for discovery)
• Manual campaigns (for control)
👉 This improves efficiency and data insights
6.Focus on Conversion Rate Optimization
Improve:
• Pricing
• Reviews
• Product presentation
👉 Higher conversions = Lower ACoS
