Amazon ACOS stands for "Advertising Cost of Sales" and is a metric used in Amazon PPC campaigns to measure the effectiveness and profitability of advertising spend. 

It is expressed as a percentage and represents the amount spent on advertising compared to the revenue generated from those advertising efforts. A lower ACOS indicates a more profitable campaign, while a higher ACOS means the campaign is less profitable. Understanding and optimising ACOS is critical to the success of an Amazon PPC campaign.

1. Understanding ACOS

Understanding ACOS is crucial for Amazon sellers because it is a key metric used to measure the effectiveness of their advertising campaigns. ACOS, or Advertising Cost of Sales, represents the percentage of sales revenue a seller spends on advertising. By monitoring ACOS, sellers can determine if their campaigns are profitable or need to adjust their PPC strategies to improve their ROI. 

Additionally, ACOS helps sellers decide their advertising budgets and which campaigns to prioritise. A thorough understanding of ACOS can help sellers optimise their Amazon PPC campaigns and increase profitability.


2. What Is Amazon ACOS?

ACOS represents the percentage of sales revenue that is spent on advertising.

The Amazon ACOS formula is as follows:

ACOS = (Advertising Cost ÷ Total Ad Sales) x 100%

For example, if a seller spends $100 on advertising and generates $1,000 in sales, the ACOS would be 10%:

ACOS = ($100 ÷ $1,000) x 100% = 10%

In this case, the seller spent 10% of their sales revenue on advertising.

3. Difference Between ACOS And ROAS

ACOS and ROAS are critical metrics for gauging the effectiveness of Amazon PPC campaigns, but they highlight different aspects of your advertising performance.

ACOS is the percentage of direct sales you've made from a particular ad compared to how much you've spent on that ad. It's calculated by dividing the total ad spend by the total ad sales generated from the ads. A lower ACOS implies you're spending less to make a sale, which is generally more favorable.

On the other hand, ROAS represents how much revenue you're generating for every dollar spent on advertising. It's determined by dividing the revenue generated from the ads by the total ad spend. A higher ROAS is better, indicating that you're generating more sales for each dollar spent on advertising.

While both are important, they offer different perspectives: ACOS looks at the cost-effectiveness of the ad relative to sales, while ROAS measures the gross revenue yield from each dollar spent on advertising. Both need to be assessed to understand the performance of your Amazon PPC campaigns fully.

4. What Is A Good ACOS For Amazon PPC

A "good" ACOS for Amazon PPC can vary depending on the product, industry, and advertising goals.

However, a general benchmark is an ACOS of 15-30%, meaning that for every dollar spent on advertising, you generate 70-85 cents in profit. It's important to keep in mind that the ideal ACOS can also depend on the seller's goals, such as increasing visibility or driving sales.

Therefore, it's crucial to evaluate ACOS in conjunction with other metrics and adjust strategies accordingly.

5. How ACOS Impacts Amazon Sellers

ACOS (Advertising Cost of Sales) is an important metric for Amazon sellers because it directly impacts their profit margins. A high ACOS means that advertising costs are eating into their sales revenue, reducing their profitability. On the other hand, a low ACOS indicates that advertising is efficient and effective in generating sales.

By understanding their ACOS, sellers can make informed decisions about their advertising budgets and strategies to maximise their return on investment (ROI). Overall, ACOS is a crucial metric for Amazon sellers to monitor and optimise to ensure their advertising efforts deliver the desired results.

Measuring Profitability

ACOS plays a critical role in measuring the profitability of Amazon sellers, especially for those who rely on Amazon PPC campaigns to drive sales. By calculating ACOS, sellers can determine the effectiveness of their advertising campaigns and adjust their strategies to maximise profitability.

ACOS and PPC campaigns are closely related because ACOS measures the direct impact of advertising spending on sales revenue. When sellers run PPC campaigns, they set a maximum bid for each keyword and pay a fee each time a customer clicks on their ad. This advertising spend contributes to the total cost of sales, which is used to calculate ACOS.

By tracking ACOS over time, sellers can determine the optimal bid for each keyword and adjust their advertising spend accordingly. For example, if a keyword has a high ACOS, sellers may need to lower their bid or revise their ad targeting to reduce costs and improve profitability.

On the other hand, if a keyword has a low ACOS, sellers may want to increase their bid to maximise exposure and drive more sales.

6. Strategies To Improve Amazon ACOS

Strategies to improve Amazon ACOS involve implementing best practices and tips for optimising PPC campaigns, improving product listings, and reducing wasteful spending. Here are some strategies:

  1. Targeting the right keywords: Conduct keyword research and choose keywords that are relevant to your product and have a high search volume. Use negative keywords to avoid irrelevant clicks.

  2. Optimising product listings: Optimise product titles, descriptions, and images to improve their relevance and appeal to shoppers. This can help improve click-through (CTR) and conversion rates, leading to lower ACOS.

  3. Refining targeting options: Use targeting options such as product/category and contextual/audience.  Sellers can further refine categories based on price, brand and star ratings. Audience targeting can be refined based on lifestyle, interests, life events and In-Market.

  4. Adjusting bids: Monitor performance regularly and adjust bids to ensure that you are not overpaying for clicks. Consider adjusting bids based on the performance of individual keywords or products.

  5. Monitoring negative keywords: Regularly monitor and update your negative keyword list to avoid showing up for irrelevant search terms. This can help reduce wasted spend and improve ACOS.

  6. Testing ad types and formats: Experiment with different formats to see what works best for your product. This can help improve CTR and conversion rates, leading to lower ACOS.

Monitoring and adjusting campaigns regularly is essential for Amazon sellers who want to improve their ACOS. Regular monitoring of campaigns allows sellers to see opportunities to optimise their ads and reduce their ACOS.

Additionally, adjusting campaigns based on performance data can help sellers identify which keywords, ad groups, and campaigns generate the best results and allocate their ad spend accordingly. By making these adjustments, sellers can improve their ACOS and maximise their profitability on the Amazon platform.

7. Common Mistakes To Avoid

  1. Setting a low ACOS target without considering the product's profitability: While having a low ACOS is desirable, it should not come at the expense of profitability. A low ACOS target may result in lower sales and decreased profitability.

  2. Not monitoring campaigns regularly: Failing to monitor campaigns regularly can result in wasted ad spend and higher ACOS. Reviewing campaigns regularly and adjusting bids, keywords, and targeting to optimise performance is important.

  3. Not optimising product listings: Product listings play a crucial role in determining the success of PPC campaigns. Failing to optimise product listings can result in lower conversion rates, higher bounce rates, and higher ACOS.

  4. Targeting the wrong keywords: Targeting the wrong keywords can result in wasted ad spend and higher ACOS. It's important to research and target keywords relevant to the product and with a high search volume.

  5. Ignoring negative keywords: Negative keywords are search terms irrelevant to the product and can result in wasted ad spend. Identifying and adding negative keywords to campaigns is important to avoid irrelevant clicks and lower ACOS.
