How To Optimize Amazon Ads: Sponsored Products & ACOS Guide

Amazon is the largest e-commerce marketplace in the world, and Amazon Ads is the fastest way to get your products in front of ready-to-buy shoppers. But with the wrong strategy, you can burn through budget without seeing a return. This guide walks you through optimizing Amazon Sponsored Products and lowering your ACOS.

Understanding Amazon Ad Types

• Sponsored Products: Ads for individual products that appear in search results and product pages. The core of most Amazon ad strategies.
• Sponsored Brands: Banner ads featuring your brand logo and multiple products. Good for brand awareness and category dominance.
• Sponsored Display: Display ads that retarget shoppers who viewed your products or competitor products.
• Stores: Custom brand storefronts that showcase your full catalog.

Step 1: Master Your ACOS & TACOS

ACOS (Advertising Cost of Sales) = Ad Spend ÷ Ad Revenue. It tells you what percentage of your ad revenue goes to ad spend. A 25% ACOS means you spend $0.25 for every $1 of ad revenue.

TACOS (Total ACOS) = Total Ad Spend ÷ Total Revenue (organic + ad). This shows the true impact of your ads on your overall business. A low ACOS with a high TACOS means your ads aren't driving incremental growth.

Target ACOS varies by category and margin. High-margin products can tolerate 30–50% ACOS. Low-margin products need 10–20%.

Step 2: Structure Your Sponsored Products Campaigns

Use a three-campaign structure for each product:

• Auto Campaign: Let Amazon target your product automatically. Use it to discover new keywords.
• Manual — Exact Match: Target your highest-converting keywords with precise bidding.
• Manual — Broad/Phrase Match: Capture related search terms with wider targeting.

Run all three simultaneously. Harvest high-performing search terms from your Auto campaign and add them to your Manual Exact campaign. Add poor performers as negative keywords.

Step 3: Keyword Research for Amazon

Use Amazon's search term report and tools like Helium 10 or Jungle Scout to find:

• High-volume keywords relevant to your product
• Long-tail keywords with lower competition
• Competitor ASINs to target with product targeting
• Search terms that convert but have low CPC

Step 4: Add Negative Keywords

Review your search term report weekly. Add negative keywords for:

• Irrelevant product searches (e.g., “cheap,” “free”)
• Wrong category or product type searches
• High-click, zero-conversion terms
• Competitor terms that don't convert for you

Negative keywords can reduce wasted spend by 20–40% on Amazon.

Step 5: Optimize Your Product Listing

Your ad gets the click, but your listing gets the sale. Optimize:

• Title: Include primary keyword, brand, and key feature
• Main image: White background, high resolution, fills 85%+ of frame
• Infographics: Show key features, dimensions, and benefits visually
• A+ Content: Use enhanced brand content to tell your product story
• Reviews: More reviews = higher conversion rate. Use compliant review request strategies.

Step 6: Bid Optimization

Adjust bids based on performance:

• Increase bids on keywords with low ACOS and high conversion
• Lower bids on keywords with high ACOS but some conversions
• Pause keywords with high spend and zero conversions
• Use dynamic bidding (up/down) for campaigns with conversion data

Step 7: Monitor & Scale

Review weekly and optimize based on:

• ACOS by campaign, keyword, and placement
• Conversion rate by search term
• Organic rank impact (are your ads lifting organic sales?)
• Placement performance (top of search vs. rest of search)
