Mastering Amazon PPC in 2025: Top Strategies to Boost Sales & Lower ACOS

Amazon PPC (Pay-Per-Click) advertising remains one of the most effective levers for growing sales and visibility on the world’s largest marketplace. As competition intensifies in 2025, sellers must evolve beyond basic tactics and adopt advanced, data-driven strategies to maximize ROI and keep Advertising Cost of Sale (ACOS) under control. This guide distills the latest Amazon PPC tips and actionable strategies-based on expert advice and proven frameworks-to help you structure, optimize, and scale your campaigns for success.

Introduction

Amazon PPC is the engine behind many of the platform’s best-selling products. With over $38 billion in ad revenue generated in 2023, the importance of mastering Amazon advertising is clearer than ever. Effective PPC campaigns can drive your product to the top of search results, fuel organic ranking, and unlock new customer segments.

This article delivers a comprehensive, step-by-step playbook for Amazon sellers-whether you’re just starting or looking to refine your approach. You’ll learn how to structure campaigns, leverage dynamic bidding, isolate keywords, optimize placements, and future-proof your strategy for ongoing success.

Understanding Amazon PPC Fundamentals

Amazon PPC offers several ad types, each with distinct functions:

• Sponsored Products: Appear in search results and on product pages; ideal for direct product promotion.
• Sponsored Brands: Feature your brand logo and multiple products; great for building brand awareness.
• Sponsored Display: Retargets shoppers on and off Amazon, expanding your reach to external sites and apps.

Key Metrics:

• ACOS (Advertising Cost of Sale): Measures ad spend as a percentage of sales. Lower ACOS means higher efficiency.
• ROAS (Return on Ad Spend): Revenue generated per dollar spent on ads.
• CTR (Click-Through Rate): The percentage of impressions that result in clicks.
• CPC (Cost Per Click): The average amount paid for each ad click.

Common Mistakes:

• Overlapping keywords across campaigns, leading to wasted spend.
• Ignoring negative keywords, which causes budget bleed.
• Focusing only on manual or automatic campaigns, missing out on discovery or control.

Strategic Campaign Structuring

A. Using Dynamic Bidding

Amazon offers three bidding strategies:

• Fixed Bids: Same bid every time, regardless of conversion likelihood.
• Dynamic Bids – Down Only: Amazon lowers your bid in real time when a conversion is less likely.
• Dynamic Bids – Up and Down: Amazon increases or decreases your bid based on conversion probability.

Best Practice:
Select Dynamic Bids – Down Only for most campaigns. This approach reduces your bid when Amazon predicts a lower chance of conversion, minimizing wasted ad spend and helping lower ACOS.

B. Manual vs. Automatic Campaigns

• Manual Campaigns: You select the keywords or products to target. Use phrase and broad match for research and testing, then migrate top performers to exact match.
• Automatic Campaigns: Amazon automatically matches your ads to relevant keywords and products, ideal for keyword discovery and seasonal trends.

Pro Tip:
Run both campaign types in parallel:

• Auto (Discover): Uncover new, high-converting search terms.
• Manual (Research): Test and refine known keywords.
• Performance Campaign: Exact match for your best search terms.

Campaigns that combine manual and automatic targeting typically see up to 19% lower ACOS due to better keyword coverage and control.

The Power of Negative Keywords

Negative keywords are essential for budget control and campaign efficiency. They prevent your ads from appearing for irrelevant or underperforming searches.

Two Key Uses:

• Keyword Isolation: Prevents overlap between automatic and manual campaigns. Add your manual campaign’s keywords as negative phrase in your automatic campaign to avoid internal competition.
• Performance Filtering: Regularly review your search term reports. Add high-ACOS or irrelevant search terms as negative exact to stop wasteful spending without blocking valuable variations.

Example:
If "blue laptop stand" is draining your budget at a high ACOS, add it as a negative exact keyword. This can result in a 24% ACOS drop by focusing spend on better-performing terms.

Creating a Performance Campaign

A Performance Campaign is a manual, exact match campaign containing only your top-performing search terms.

How to Build One:

• Mine your auto and manual campaign search term reports for the lowest ACOS, highest-converting keywords.
• Add these as exact match keywords in a new campaign.
• Simultaneously, add these terms as negative exact in your other campaigns to maintain keyword isolation.

Benefits:

• Granular control over bids for your best keywords.
• Ability to allocate more budget to proven revenue drivers.
• Streamlined optimization loop:
  Discover (Auto) → Research (Manual Broad/Phrase) → Performance (Manual Exact)

Placement Optimization Explained

Amazon offers three main ad placements:

• Top of Search: First few results on the search page-typically highest-converting.
• Rest of Search: Remaining positions in search results.
• Product Pages: Ads on competitor or related product listings.

Optimization Steps:

• Access placement performance reports in Seller Central.
• Identify which placements yield the best ACOS and ROAS.
• Adjust placement bid modifiers:
  • Increase bids (e.g., +20%) for top-performing placements like Top of Search.
  • Decrease overall keyword bids to offset higher placement bids, keeping ACOS in check12.

Example:
If Top of Search delivers 50% better ROAS than Product Pages, increase its bid adjustment while reducing base bids to optimize spend.

Real-Life Case Study

A seller implemented Dynamic Bids – Down Only, ran both auto and manual campaigns, and used negative keywords for isolation and performance filtering. By migrating top search terms to a Performance Campaign and optimizing placements, they achieved an ACOS below 40%-driving more sales at a lower cost12.

Future-Proofing Your PPC Strategy

• Monitor Trends: Regularly analyze seasonal keywords and adjust bids for peak periods.
• Stay Updated: Follow Amazon advertising updates to leverage new features and formats.
• Leverage Tools: Use third-party platforms like Helium 10 or Jungle Scout for keyword research, automation, and reporting.

AI and machine learning are increasingly integral to Amazon PPC, enabling real-time bid adjustments, advanced targeting, and smarter budget allocation.
