Below are six proven ways an Amazon marketing agency can help you achieve better results.

1. Strategic Bid Management and Monitoring

Effective bid management is the foundation of Amazon ACoS reduction. An agency uses data-driven techniques to adjust bids for keywords, placements, and products based on their profitability and conversion performance.

Key steps agencies take:

• Automated bid rules: Lower bids for keywords with low conversions and raise bids for high-performing terms.
• Match type segmentation: Manage exact, phrase, and broad match keywords separately for better control.
• Placement bid adjustments: Increase bids for top-performing placements and reduce spend on underperforming areas to ensure you set the right bid amount for optimal results.

By actively managing bids, agencies maintain competitiveness while avoiding overspending on unprofitable clicks.

2. Keyword Targeting with Buyer Intent Focus

High ACoS often comes from targeting broad, high-competition keywords. Agencies focus on choosing the right keywords, particularly long-tail keywords that signal stronger buying intent, helping improve click-through rates and conversions.

Why this works:

• Lower CPCs: Long-tail terms usually have less competition.
• Higher conversion potential: These terms often match a shopper’s specific needs.
• Better match to product benefits: Keywords align closely with the listing’s value proposition.

Agencies also refine targeting by continuously analyzing search term reports to remove irrelevant terms. This ensures that every click has a higher probability of turning into a sale, contributing to the average ACoS on Amazon reduction.

3. Negative Keyword and Target Optimization

One of the fastest ways to reduce Amazon PPC Total ACoS is by eliminating wasted spend through negative targeting in your best practices for Amazon PPC campaigns, advertising strategy, and overall Amazon advertising strategy campaigns.

Agencies monitor search term reports to find keywords or ASIN targets that drive clicks without generating sales, ultimately improving campaign performance at the best times using Amazon PPC tools.

Agency process:

• Add negatives: Block irrelevant or poor-performing keywords.
• ASIN exclusions: Avoid placements against unrelated or overly competitive products.
• Performance filters: Remove search terms exceeding target ACoS thresholds.

This approach keeps ad spend focused on high-return opportunities, helping sellers reach the ideal ACoS on Amazon should be between their profitability range.

4. Placement and ASIN Targeting Optimization

An experienced Amazon marketing agency uses placement and ASIN targeting to place ads in the most profitable locations.

Agency techniques include:

• Top-of-search optimization: Boost bids where conversion rates are higher.
• Product targeting: Target complementary or substitute products to capture interested shoppers.
• Defensive targeting: Place ads on your own listings to protect against competitor ads.

By allocating more budget to high-performing placements, agencies ensure that ads work harder for every dollar spent.

5. Listing Optimization for Higher Conversion Rates

Even the best keyword and bidding strategy will fail if the product listing does not convert. A low conversion rate drives up ACoS Amazon meaning that more clicks are required to generate sales.

Agency enhancements include:

• Compelling titles and bullet points that highlight benefits and features.
• High-quality images and videos to build trust and engagement.
• A+ Content and Brand Stores to create a richer shopping experience.
• Review generation strategies to build credibility.

Improved listings reduce the cost per sale and boost organic ranking, further lowering dependency on ads and contributing to how to get a good ACoS on Amazon.

6. Data-Driven Campaign Structuring and Scaling

An agency structures campaigns to allow precise ad budget control, performance tracking, and scalable growth.

Typical structure:

• Separate campaigns for product categories or goals to isolate performance.
• Single Product Ad Groups (SPAGs) to monitor keyword-level results.
• Balanced mix of automatic and manual campaigns for discovery and control.

Ongoing performance analysis is critical. Agencies use metrics such as TACoS, CTR, and CVR to refine targeting. They may also employ an Amazon ACoS calculator to track profitability in real time and align campaigns with the ACoS Amazon formula.

Why Reducing ACoS Matters

Lower ACoS protects your margins and keeps ad dollars focused on clicks that convert. The core moves are simple: bid with intent, target with precision, block waste, optimize listings for conversion, and structure campaigns so data guides every change.

What Works Best

• Tune bids by performance: Raise bids on proven exact-match terms and strong placements; cut bids on low-converting broad terms. The post’s example shows ACoS dropping from 35% to 22% after smart bid adjustments, while trimming wasted spend on weak terms.
• Target buyer intent: Long-tail keywords cost less and convert better because they match specific needs; keep refining with search term reports to remove mismatched queries.
• Add negative keywords and targets: Stop paying for clicks that never convert by blocking irrelevant queries and poor ASIN targets; review reports weekly to keep waste low.
• Optimize listings to convert: Improve images, titles, bullets, and A+ content so traffic turns into sales; your best ad return comes from strong product pages.
• Structure for clarity and scale: Segment match types, separate product groups, and use placement controls so you can shift budget quickly to winners and pause losers.

How to Apply This Week

• Set automated bid rules that nudge bids up on high-converting terms and down on low performers; check placement reports and adjust multipliers.
• Pull your last 30 days of search term data; add negatives for any term with spend but no sales, and promote converting queries to exact match.
• Refresh top listings: tighten titles around primary benefits, upgrade images, and align bullets with the keywords that actually convert.
• Create a simple campaign map: one campaign per goal, ad groups split by match type, and clear budgets you can scale when ACoS stays within target.

What to Watch

• ACoS and conversion rate per keyword, not just at the campaign level.
• Placement performance; top-of-search often wins, but only if it converts at your target.
• Waste indicators: rising clicks with flat orders, or high spend on vague, broad terms.
