How to Lower ACoS for New Amazon Products

This article will combine real-case scenarios to break down two core optimization strategies in detail. It will also demonstrate how to use MasLogin Anti-Detection Browser for secure multi-account management and efficient ad testing, helping you gradually optimize your ACoS from 69% to an ideal range of 15-20%.

Why is Amazon Advertising ACoS So High?

In actual operations, excessively high ACoS is typically caused by the following factors:

• Blindly Choosing Advertising Time Slots: Certain periods (like weekends) experience significantly lower conversion rates, yet ads continue to run, draining budget.
• Inaccurate Keyword Match Types: Using "Broad Match" causes ads to be displayed to irrelevant users.
• Overly Aggressive Bidding Strategies: Blindly following Amazon's suggested bids leads to uncontrolled costs.
• Ignoring Product Targeting Ads: Over-reliance on keyword advertising misses more efficient traffic entry points.

For example, a seller found their ACoS soaring to 175% on April 15th (Saturday)—spending $17.5 to generate only $10 in sales. If such abnormal data isn't detected and adjusted promptly, it severely impacts overall ad efficiency.

Strategy 1: Optimize Advertising Timeslots Using Data Trend Charts

How to Identify "Budget-Burning" Periods

In Amazon's Campaign Manager, charts visually display the trends of ad spend (blue line) and ACoS (purple line). When you observe that the ACoS on a particular day is significantly higher than the average, you need to analyze:

1. What day of the week is it?
2. Are there any holidays or special events?
3. Is the conversion rate noticeably lower than on other days?

Real Case Example: In the aforementioned scenario, the ACoS reached 175% on Saturday, April 15th, while it averaged below 50% on other weekdays. Analysis revealed that while users are online longer on weekends, their purchase decision rate is significantly lower than on weekdays (especially Tuesdays to Thursdays).

Optimization Steps

• Pause ad campaigns on Saturdays and Sundays.
• Resume ads on Mondays.
• Monitor data for 1-2 weeks to confirm if ACoS has effectively decreased.

This simple adjustment can directly eliminate wasted spending and concentrate ad budgets on high-conversion periods.

Strategy 2: Compare the Efficiency of Keyword Targeting Ads and Product Targeting Ads

Differences Between the Two Ad Types

Many sellers only use Keyword Targeting ads, overlooking the immense potential of Product Targeting ads.

• Keyword Targeting: Your product appears on the search results page when users search for specific keywords.
• Product Targeting: Your product appears in the "Frequently Bought Together" or "Sponsored Products Related to this Item" sections on competitor product detail pages.

Real Comparative Data:

As seen, Product Targeting ads have an ROAS that is over 8 times higher than Keyword Targeting ads, with an ACoS of only 6.2%.

Why Are Product Targeting Ads More Efficient?

• Users are already browsing similar products, indicating a clearer purchase intent.
• Ad placements are less conspicuous, with relatively lower competition.
• Cost Per Click (CPC) is generally lower than for keyword ads.

Optimization Recommendations

New Product Promotion Phase (0-50 Reviews):

• Run Keyword Targeting and Product Targeting ads concurrently.
• Use Keyword Targeting to quickly gain exposure and initial orders.
• Utilize Product Targeting to precisely capture high-intent users.

Maturity Phase (50+ Reviews):

• Gradually reduce the budget for Keyword Targeting ads.
• Focus investment on Product Targeting ads.
• Maintain a low ACoS while stabilizing sales.

Strategy 3: Refine Keyword Management and Bidding

Step 1: Eliminate Ineffective Keywords

Navigate to the "Targeting" page within your ad group and filter using the following rules:

1. Spend > $10 with 0 Orders: Pause these keywords immediately.
2. ROAS < 2.0: Pause or reduce bids.
3. ROAS Between 2.0-4.0: Check if the bid is too high and adjust moderately.
4. ROAS > 4.0: Retain and increase budget for these keywords.

Example: A seller found that "golf towels" (Broad Match) spent $15 without generating any orders, while "golf towels for men" (Exact Match) only cost $5 and yielded an order with a ROAS of 5.89. Pausing the former led to a 12% decrease in overall ACoS.

Step 2: Use Exact Match Exclusively

Amazon offers three keyword match types:

• Broad Match: Your ad may display when a user searches for "golf accessories" (wastes budget).
• Phrase Match: Your ad displays when a user searches for "men's golf towel" (moderate precision).
• Exact Match: Your ad only displays when a user searches for "golf towel" (Recommended).

Optimization Advice: In keyword advertising, use 100% Exact Match to avoid wasting budget on irrelevant traffic.

Step 3: Use the Coefficient Method for Rapid Bid Adjustments

This is a practical mathematical optimization method:

Calculation Formula:

Optimization Coefficient = Current ACoS ÷ Target ACoS
New Bid = Current Bid ÷ Optimization Coefficient

Example:

• Current ACoS: 57.36%
• Target ACoS: 20%
• Coefficient = 57.36 ÷ 20 = 2.9

If a keyword's current bid is $1.19, the adjusted bid = $1.19 ÷ 2.9 = $0.41.

Important Notes:

• Impressions will decrease after adjustment.
• However, ad slots may still be won during low-competition periods.
• Observe data for 3-7 days before deciding on further adjustments.

How MasLogin Assists in Amazon Advertising Optimization?

In practice, many professional sellers need to manage multiple Amazon accounts (e.g., different marketplaces, multi-brand stores) or frequently switch environments when testing ads. At this point, MasLogin Anti-Detection Browser becomes an essential tool.

Core Pain Points and Solutions

Pain Point 1: Risk of Multi-Account Association

Amazon detects account association through technologies like browser fingerprinting, IP addresses, and Cookies. Once associated, all accounts may be banned simultaneously.

MasLogin Solution:

• Create an independent browser environment for each account.
• Isolate Cookies, cache, Canvas fingerprints, and other data.
• Use in conjunction with proxy IPs to ensure each account's login environment is completely separate.

Pain Point 2: Inefficient Ad Testing

When testing ad performance in different regions, frequent switching of IPs and browser environments can trigger platform risk controls.

MasLogin Solution:

• Preset multiple browser configurations (USA, Europe, Japan, etc.).
• Switch between different regional environments with one click.
• Automatically synchronize proxy IPs and browser fingerprints, eliminating manual configuration.

Pain Point 3: Chaotic Team Collaboration

When multiple individuals manage ad accounts, unclear permission assignments can lead to accidental operations or data breaches.

MasLogin Solution:

• Supports sharing browser environments among team members (read-only/edit permissions).

Step 4: Use the coefficient method for bulk bid adjustments to lower ACoS.

Step 5: Utilize MasLogin for multi-account management and to enhance testing efficiency and security.

Step 6: Review data weekly and continuously iterate and optimize.

Frequently Asked Questions

1. Will lowering bids lead to no ad exposure at all?

No. Even with lower bids, ad slots can still be won during less competitive times (e.g., early morning hours). It is recommended to observe data for 3-7 days after adjustment. If impressions fall below expectations, slightly increase the bid (10-15% per adjustment).

2. How to choose competitor products for Product Targeting ads?

Go to the "Product Targeting" page in the ad backend, enter your core keywords, and Amazon will recommend relevant products. Prioritize products with:

• Ratings between 3.5-4.5 (products with very high ratings are hard to convert, while low ratings affect conversion).
• Prices close to yours.
• BSR (Best Seller Rank) within your top 50-200.

3. Will using MasLogin be detected by Amazon?

MasLogin uses real browser environment isolation + independent proxy IPs to simulate normal user behavior, thus avoiding platform risk controls. The key is to:

• Use high-quality residential proxies (avoid datacenter IPs).
• Maintain a consistent browser environment and IP for each account.
• Operate naturally (avoid frequent account switching in a short period).

4. What is a normal ACoS for new product promotions?

• First 2 weeks of new product launch: ACoS of 50-70% is acceptable (focus is on acquiring reviews and ranking).
• Weeks 3-4: Optimize to 30-40%.
• Stable period (50+ reviews): Target 15-25%.

5. How to determine if a keyword is worth continuing to advertise?

It should meet both of the following conditions to be retained:

• ROAS > 2.0
• Click-Through Rate (CTR) > 0.3%

If ROAS < 2.0 or CTR is too low, consider pausing or changing the keyword.

Conclusion

Amazon advertising optimization is a continuous iterative process. By analyzing data to identify inefficient areas, utilizing product targeting ads to improve ROAS, and meticulously managing keywords and bids, ACoS can be significantly reduced. Furthermore, MasLogin provides secure and stable technical support for multi-account management and efficient testing, helping sellers maintain a competitive edge.
