Mastering Amazon ACoS and RoAS Metrics for Advertising Analytics

As an Amazon seller, you know that optimizing your advertising is crucial to boosting sales and profits. But with so many metrics to track, it can be challenging to interpret the data and determine the right strategies. In this article, you’ll learn how to leverage two key performance indicators — ACoS and RoAS — to gain actionable insights.

We’ll explain what these acronyms stand for, how to calculate and analyze them, and most importantly, how to use your findings to fine-tune your Amazon PPC campaigns and product targeting for maximum return. With the right analytics approach, you’ll be able to consistently improve the efficiency of your advertising spend. This article will provide the knowledge you need to master these vital metrics and make data-driven decisions to optimize your Amazon ads.

Understanding Amazon ACoS and RoAS

What is Amazon ACoS?

Amazon ACoS refers to your advertising cost of sale, expressed as a percentage. It tells you how much you’re spending to generate one dollar of revenue from your Amazon advertising campaigns. To calculate your ACoS, take your total advertising spend over a given period of time and divide it by the total sales generated from those ads over the same time period.

Why is ACoS important?

A low ACoS, such as 5–15%, means your advertising spend is efficient and generating strong returns. A high ACoS, over 25%, means your ads may not be profitable and you should re-evaluate your targeting and bids. Monitoring your ACoS regularly and making adjustments can help maximize your advertising ROI.

What is Amazon RoAS?

RoAS stands for return on advertising spend. It’s calculated by dividing the total revenue generated from your ads by your total advertising cost over a given time period. For example, if you spent $10,000 on ads and generated $30,000 in revenue, your RoAS would be 3:1. The higher your RoAS, the more efficient and profitable your advertising is.

Using ACoS and RoAS together

ACoS and RoAS provide different but complementary insights into your advertising performance. ACoS shows how much you’re spending for each dollar of sales, while RoAS shows your total return for every dollar spent. Tracking both metrics over time and making changes to improve them can help drive more value from your advertising budget.

Monitoring and optimizing your ACoS and RoAS is key to success with Amazon advertising. Make these metrics a regular part of your advertising analytics and be ready to adjust bids, target new keywords, and refine your campaigns to achieve your goals. With consistent optimization, you’ll maximize your advertising ROI and gain greater visibility for your products.

What Is Amazon ACoS (Advertising Cost of Sale)?

Amazon ACoS is one of the most important metrics for analyzing the effectiveness of your Amazon advertising campaigns. ACoS stands for “Advertising Cost of Sale” and is calculated as the amount you spend on advertising divided by the revenue generated from those ad clicks. For example, if you spend $100 on ads and make $200 in revenue from customers who clicked those ads, your ACoS would be 50%.

Why Is ACoS Important?

A low ACoS means your advertising spend is efficient since you’re earning more in revenue than you’re spending on ads. Most sellers aim for an ACoS below 35%. A high ACoS means your ad spend is inefficient and you’re paying more for ads than you’re making in return. You’ll want to optimize your ads and targeting to lower your ACoS.

How to Calculate and Optimize Your ACoS

You can find your ACoS for each campaign in your Amazon Advertising reports. Divide your total advertising cost by the total revenue generated from ad clicks. Make sure you’re only including revenue from sales that actually resulted from ad clicks, not organic sales or sales from other channels.

To optimize your ACoS, try:

• Improving your ad copy and images to increase click-through rate. More clicks at the same spend will lower your ACoS.

• Refining your targeting to reach high-intent shoppers. Showing your ads to shoppers more likely to convert will boost revenue and in turn lower your ACoS.

• Increasing your bids for high-performing keywords and decreasing bids for underperforming keywords. This helps drive more traffic to your most effective ads.

• Excluding poorly performing keywords and placements. Stop showing your ads where they aren’t generating a good return on investment.

• Creating promotions or offers for customers who engage with your ads. Special offers will increase conversion rates and revenue from your ads.

By regularly monitoring and optimizing your ACoS, you can significantly improve the performance of your Amazon advertising and ensure you’re getting the most out of your ad spend. Keep testing and making changes to find the sweet spot where your ads are profitable and effective.

What Is Amazon RoAS (Return on Advertising Spend)?

Defining RoAS

RoAS stands for Return on Advertising Spend. It is a metric used by Amazon sellers and vendors to evaluate the effectiveness of their advertising campaigns. RoAS measures the revenue generated from advertising efforts divided by the total amount spent on advertising. A higher RoAS means that a campaign is generating more revenue per dollar spent, indicating it is more effective.

Calculating Your RoAS

To calculate your RoAS, you will need to determine your advertising revenue and costs. Your advertising revenue includes all sales that were generated from your ads, including products, shipping, and any additional services. Your advertising costs include the total amount spent on Sponsored Products & Sponsored Brands, and any other Amazon advertising during the time period you want to analyze.

Divide your advertising revenue by your advertising costs to determine your RoAS. For example, if you generated $10,000 in revenue from $5,000 in ad spend, your RoAS would be 2 ($10,000/$5,000).

Improving Your RoAS

There are several strategies you can implement to improve your RoAS. Focusing your ads on high-margin products, optimizing your ad copy and images, and refining your targeting to reach potential customers more likely to convert can all help increase your RoAS. You should also analyze which ad types and campaigns are performing best and allocate more of your budget to them.

Monitoring your RoAS regularly and making ongoing optimization changes and improvements allows you to maximize the effectiveness of your advertising budget. An increasing RoAS over time means your advertising strategies are working and you are gaining more benefit for every dollar spent. RoAS, along with other key metrics like ACoS, should be an integral part of your advertising analytics and optimization process.

How to Calculate and Analyze Your ACoS

Calculate Your ACoS

To calculate your ACoS (Advertising Cost of Sale), you will need to know your advertising spend and sales attributed to your ads over a given time period. Take your total advertising spend and divide it by your total sales from ads. For example, if you spent $10,000 on ads last month and made $50,000 in sales from those ads, your ACoS would be 20% ($10,000 / $50,000).

Analyze How Your ACoS Compares

Compare your ACoS to the industry average, which is around 15–20% for most product categories. If your ACoS is higher than the average, you may need to optimize your ads and campaigns to improve performance. Look for ways to increase sales or decrease spend. You can also compare your ACoS month over month to see if it’s trending up or down, and make changes accordingly.

See How Your ACoS Affects Your Return on Ad Spend (RoAS)

Your ACoS directly impacts your RoAS, which is your total sales revenue divided by your ad spend. Using the example above, a 20% ACoS ($10,000 spend and $50,000 sales) would give you an RoAS of 5x ($50,000 / $10,000). The lower your ACoS, the higher your RoAS will be. Most companies aim for an RoAS of at least 3–5x to make their ad spend profitable.

Optimize Based on Your Findings

If your ACoS is too high, you’ll need to optimize your ads and campaigns. Some suggestions include: choosing higher-converting keywords, improving your ad copy, refining your target audiences, and A/B testing different ad creatives. You can also set an ACoS target, like 15–20%, and pause or restructure underperforming ads and campaigns to meet your goals. Continually monitor and optimize your ACoS and RoAS to maximize the profitability of your Amazon advertising.

In summary, calculating and analyzing your ACoS and RoAS metrics regularly is key to managing a successful advertising campaign on Amazon. Make changes as needed to keep your ACoS and RoAS within target ranges, and you’ll achieve profitable results from your ad spend.

How to Calculate and Analyze Your RoAS

To effectively optimize your Amazon advertising campaigns, you must analyze key metrics like Return on Ad Spend (RoAS). RoAS measures the revenue generated from your ads versus how much you spend on them. A higher RoAS means your ads are more profitable.

Calculating Your RoAS

To calculate your RoAS, take the total revenue from products sold through your ads and divide it by how much you spent on advertising those products. For example, if you spent $1,000 on ads last month and made $2,000 in revenue from products sold through those ads, your RoAS would be 2 ($2,000 revenue / $1,000 ad spend). The higher your RoAS, the better. An RoAS over 2 is typically considered good.

Analyzing and Optimizing Your RoAS

Once you know your RoAS, analyze which factors are impacting it. Look at metrics like click-through rate, conversion rate, and average order value for your ads. Ads with higher click-through and conversion rates and bigger basket sizes will yield a higher RoAS. You may need to refine your targeting, bids, creative, and landing page experience to improve these metrics.

Compare your RoAS across campaigns, ad groups, keywords, and product types. Look for opportunities to reallocate spend from low-performing areas to high-performing areas. You may also find new areas of opportunity to expand into.

Monitor how your RoAS changes over time to see the impact of your optimizations. Make incremental changes so you can easily see how each impacts your results. Small tweaks to your ads and bids can significantly improve your RoAS over the long run.

Continually optimizing to increase your RoAS is key to success with Amazon advertising. While a high RoAS is ideal, even slightly improving your RoAS over time can mean major increases in profit and sales. With regular analysis and optimization, you’ll be well on your way to mastering your Amazon advertising analytics.

Tips for Lowering Your ACoS

To lower your ACoS and improve the profitability of your Amazon advertising campaigns, focus on optimizing your product listings and ad copy. An optimized listing with high-quality images and a clear description of the product and its benefits can drive higher click-through rates and lower ACoS.

Enhance Your Product Listings

Ensure your product titles, images, and bullet points clearly convey what the product is and its key selling points. Use dynamic images that showcase the product from multiple angles. The first 2–3 images are the most important, as that is all shoppers see in the search results.

Optimize Your Ad Copy

Your sponsored ad copy should highlight the most compelling benefits and features of your product to pique interest. Include your product title or key selling points, a clear call-to-action like “Buy Now,” and a strong value proposition. Test different ad copy and placements to determine which options yield the highest click-through rates at the lowest cost.

Target Relevant Keywords

Target keywords that are closely related to your product to reach high-intent shoppers. Broad terms may lead to high impressions but low click-through rates. Use Amazon Keyword Tool to find relevant keywords based on search volume and competitiveness. Bid on exact match keywords when possible for the most qualified traffic.

Set Competitive Bids

Bidding too high can quickly increase your ACoS, while bidding too low results in lost impressions and sales. Analyze the bids of competitors targeting similar keywords to determine an optimal range. Start with a mid-range bid and make incremental changes based on your performance data. You may need to bid higher for top placements that lead to more sales.

Review and Refine

Consistently review your campaign and product metrics to identify opportunities for improvement. Look at factors like click-through rate, conversion rate, and sales to determine which keywords and ad types are most profitable. Pause or remove underperforming ads and keywords. Make ongoing refinements to ad copy and bids to maximize your return on ad spend. With regular optimization, you can achieve significant ACoS reductions over time.

Tips for Increasing Your RoAS

To improve your RoAS on Amazon advertising, focus on optimizing your Product Listing Pages and sponsored ads.### Enhance Your Product Listings High-quality listings are essential for generating sales and increasing your RoAS. Include professional photos showcasing your product, an accurate and descriptive title and bullet points highlighting key features and benefits. Update the copy regularly and test different variations to see which performs best.

Bid on High-Converting Keywords

Carefully choose which keywords you want to bid on based on their conversion potential. Do research to find keywords that are relevant to your product and are likely to convert at a high rate. Start with broad match types, then move to exact match as you gather data on performance. Continually optimize your bids based on which keywords are driving the most valuable traffic and sales.

Increase Your Bids for Top Performing Keywords

If certain keywords are consistently generating a high RoAS, increase your bids for those terms to gain more impressions and traffic. Even small bid increases can significantly impact your visibility and sales. However, be cautious not to increase bids too quickly, as it may take time for the changes to impact your metrics. Closely monitor how your RoAS is affected with each bid change.

Improve Your Ad Copy

Compelling ad copy plays an important role in your RoAS. Your sponsored ad is the first thing customers see, so make a good first impression. Include your product name, key features, images and a strong call-to-action like “Buy Now.” Test different variations of your ad copy, including different wording, formatting, images, and CTAs. See which variants have the highest click-through rates and conversion rates.

Offer Promotions and Coupons

Running promotions and offering coupons or discounts is an effective way to increase sales and RoAS. Time-limited offers create a sense of urgency for customers to buy now before the promotion ends. However, be strategic in how often you run promotions, as overusing them can condition customers to only buy when items are on sale.

With continual optimization of these tips, you can significantly improve your RoAS and achieve greater success with your Amazon advertising campaigns. Monitor your metrics regularly and make incremental changes to find the right balance for your brand.

Using ACoS and RoAS Together for Optimization

To maximize the effectiveness of your Amazon advertising campaigns, using both the Advertising Cost of Sale (ACoS) and Return on Ad Spend (RoAS) metrics together can provide valuable insights. The ACoS metric calculates how much you are spending on advertising for each dollar of revenue generated. The RoAS metric determines how much revenue is generated for every dollar spent on advertising.

Monitoring your ACoS will help ensure that your ad spend remains within a reasonable proportion of your total sales revenue. An ACoS that is too high means that you are spending too much on advertising relative to the sales being generated, decreasing your profit margins. You will want to aim for an ACoS target that aligns with your business goals and product margins. For most businesses, an ACoS between 5–15% is a good target.

Your RoAS metric indicates how much revenue you are gaining for every dollar spent on advertising. A higher RoAS means that your advertising spend is more efficient and generating strong returns. An RoAS of over 100% means that for every $1 spent on advertising, you are making over $1 in revenue. The higher the RoAS, the more profitable your advertising is.

Using these metrics together can help determine the optimal balance of ad spend for your business. If your ACoS is within target but your RoAS seems low, you may need to increase your advertising budget to improve revenue. If your RoAS is high but ACoS seems excessive, you may need to scale back your ad spend to achieve better profit margins. Regularly monitoring and optimizing based on both ACoS and RoAS will help maximize the success of your Amazon advertising campaigns.

ACOS vs ROAS: Which Amazon PPC Metric Is Best

When analyzing the performance of your Amazon PPC advertising campaigns, two of the most important metrics to consider are ACoS (Advertising Cost of Sale) and ROAS (Return on Ad Spend). Both provide insight into the profitability of your ads, but in different ways. Understanding how they differ and complement each other is key to optimizing your advertising budget and maximizing your return on investment.

ACoS measures how much you spend on advertising relative to the revenue generated from those ads. It is calculated by dividing your total ad spend by the total revenue from products sold through those ads. An ACoS of 25% means that for every $1 of revenue, you spent $0.25 on advertising. The lower your ACoS, the more profitable your ads. Many Amazon sellers aim for an ACoS below 35%.

ROAS indicates how much revenue you generate for every dollar spent on advertising. It is calculated by dividing your total revenue from sales by your total ad spend. A ROAS of 4 means that for every $1 you spend on ads, you get $4 in revenue. The higher your ROAS, the more efficient your ads are. Most Amazon sellers target a ROAS of 3 or higher.

While a low ACoS and high ROAS are ideal, focusing on just one metric can be misleading. ACoS depends heavily on your profit margins and pricing, while ROAS is more indicative of sales volume. For the best results, monitor both ACoS and ROAS to ensure your ads are both profitable and driving sufficient sales. Make adjustments to your daily budget, keyword bids, and campaign targeting based on how these metrics change over time.

In summary, ACoS and ROAS provide invaluable data on the performance of your Amazon advertising campaigns. Tracking them regularly and optimizing for the most efficient combination of a low ACoS and high ROAS is the key to success with Amazon PPC. By gaining insights into both profitability and sales volume, you can make data-driven decisions to improve your ads and maximize your return on investment.
