Amazon ACoS Optimization Services

A lower ACoS isn’t always a better ACoS. Cutting advertising costs too aggressively can limit profitable sales, while a high ACoS can reduce your margins.

AMZDUDES is a full service Amazon agency that provides Amazon ACoS optimization services that set advertising targets around your product margins, business goals, and account performance. We reduce wasted spend where ACoS is too high and increase investment where additional spending can still generate profitable growth.

At a Glance

Amazon ACoS optimization is about finding the right advertising efficiency for each product, not simply pushing the percentage lower. We look at product margins, growth goals, lifecycle stage, TACoS, and campaign performance to determine where to reduce spend and where to invest more. Our team has managed $20M+ in Amazon ad spend across 300+ campaigns, including accounts where ACoS reduction was a key part of improving performance.

The Lowest ACoS Isn’t Always the Goal

A low ACoS can look good in a report, but the number alone doesn’t tell you whether your advertising is working efficiently for the business.

If ACoS is too high, you’re spending too much relative to the sales generated. But if ACoS is pushed too low, you may be under-investing in keywords, products, or campaigns that could still generate profitable sales.

The right target depends on the product and the business objective. A high-margin product with a growth target may support a higher ACoS than a low-margin product focused primarily on profitability.

Amazon ACoS optimization means finding that balance and adjusting it as performance, margins, competition, and goals change.

What We’ve Seen in Large Sellers’ Accounts

Large sellers can lose significant amounts of money when ACoS is managed with a single target or broad cost-cutting approach.

ACoS Is Too High

Branded and non-branded campaigns may be mixed, converting search terms may remain in broad match, or bids and placements may not reflect actual performance. At higher ad spend levels, small inefficiencies can add up quickly.

ACoS Is Too Low

Aggressive cost reduction can also create problems. Conservative bids and restricted budgets may prevent profitable products and keywords from receiving enough traffic.

One Target Is Used for Everything

Different products have different margins, goals, and lifecycle stages. Applying one ACoS target across the entire account can cause some products to be over-funded while others are under-invested.

ACoS Is Managed With Blunt Cuts

Lowering bids or pausing campaigns whenever ACoS increases can bring the number down without addressing why performance changed. The result can be less spend, but also fewer profitable sales.

What the Right ACoS Depends On

There isn’t one ACoS percentage that works for every product or account.

Product Margin

Products with higher margins can generally support more advertising cost than products with tight margins. ACoS targets need to reflect the economics of each product.

Business Goals

A product being pushed for growth, market share, or new customer acquisition may require a different target than a mature product being managed primarily for profit.

TACoS and Organic Performance

ACoS should be viewed alongside TACoS and organic sales. A campaign can have a strong ACoS while advertising contributes little additional growth, or a higher ACoS can be justified when advertising is helping generate broader account growth.

Product Lifecycle

Launch products, growth products, and mature products can require different advertising strategies. The target should reflect where the product is in its lifecycle.

We use these factors to set and adjust ACoS targets instead of applying one blanket percentage across the account.

At AMZDUDES How Our Team Optimizes ACOS

Our approach works in both directions: reduce waste where ACoS is too high and increase investment where additional spend can still be profitable.

1. Set the Right Target

We review product margins, goals, lifecycle stage, TACoS, and campaign performance to establish an appropriate target for each product.

2. Reduce Waste

Where ACoS is above target, we identify inefficient search terms, bids, placements, campaigns, and budgets and make targeted adjustments.

3. Invest Where It Makes Sense

Where ACoS is below the level that supports the brand’s goals, we look for opportunities to increase bids, budgets, and keyword coverage without compromising profitability.

4. Optimize Search Terms

Converting search terms are moved into more controlled campaigns, while irrelevant and inefficient terms are filtered through negative targeting.

5. Adjust Bids and Placements

Bids, placement modifiers, budgets, and other campaign controls are adjusted based on performance rather than fixed rules.

6. Monitor and Recalibrate

ACoS targets can change as margins, competition, sales volume, and business priorities change. Optimization is therefore an ongoing process, not a one-time adjustment.

ACoS, TACoS, and Profit

ACoS should not be viewed in isolation. ACoS measures advertising spend against ad-attributed sales, while TACoS measures advertising spend against total sales, including organic revenue. Looking at both helps show whether advertising is supporting broader account growth or simply capturing sales that may have happened anyway. Our ACoS optimization approach considers ACoS, TACoS, margins, product performance, and business goals together. This gives us a clearer view of where advertising should be reduced, maintained, or increased.

Frequently Asked Questions

Amazon ACoS optimization is the process of managing advertising spend toward an appropriate ACoS target based on product margins, business goals, lifecycle stage, and account performance. The goal isn’t simply to achieve the lowest possible ACoS.

Yes. An excessively low ACoS can indicate that advertising is being under-invested. Conservative bids or budgets may limit profitable traffic and sales opportunities.

The target depends on factors such as product margin, growth goals, lifecycle stage, TACoS, and overall account performance. Different products may require different targets.

Lowering ACoS focuses on reducing a high percentage. ACoS optimization considers both directions: reducing inefficient spend while increasing investment where additional advertising can still be profitable.

ACoS measures ad spend against ad-attributed sales, while TACoS measures ad spend against total sales. Looking at both provides a broader view of advertising efficiency and its relationship with organic sales.

Yes. AMZDUDES manages large and complex Amazon advertising accounts and has managed $20M+ in Amazon ad spend across 300+ campaigns.

Pricing depends on ad spend, product and brand count, campaign volume, account complexity, and the scope of management. AMZDUDES offers month-to-month engagements with pricing based on the account’s requirements.
