Amazon has become the largest e-commerce platform in the world, offering multiple opportunities for entrepreneurs and businesses to sell their products. Through its FBA (Fulfillment by Amazon) and FBM (Fulfillment by Merchant) models, sellers can choose between delegating logistics to Amazon or managing their own shipments.
However, to ensure success and profitability in this marketplace, it is essential to measure the performance of each operation. This is where KPIs (Key Performance Indicators) come into play, key metrics that make it possible to evaluate sales performance, customer satisfaction, and logistical efficiency.
Monitoring these indicators helps make data-driven strategic decisions, optimize costs, and improve the customer experience. In this article, we will explore the main KPIs on Amazon, their importance, and how they can make a difference in the sustainable growth of a business on this platform.
What are KPIs on Amazon and why are they important?
KPIs on Amazon (Key Performance Indicators) are key metrics used to evaluate product performance, customer satisfaction, and the effectiveness of business strategies on the platform. These metrics make it possible to make strategic adjustments to improve visibility, optimize costs, and increase conversion.
Unlike general metrics, which only show descriptive data, KPIs provide actionable information that makes it possible to track business goals precisely. For sellers, analyzing KPIs on Amazon is essential for making decisions based on real data.
Monitoring these indicators helps businesses and freelancers adapt to customers, optimize Amazon advertising strategy, and improve business profitability. In this way, KPIs not only help understand how a product is performing, but also drive long-term sales growth.
Main KPIs for Amazon sellers
1. Sales KPIs
Revenue or total income
This KPI measures the income generated by product sales over a given period. It is key to evaluating growth and defining optimization strategies.
Product conversion rate
It shows the percentage of users who, after visiting a product page, make a purchase. An essential KPI for identifying whether the content and offers are effective for the customer.
Average Order Value (AOV)
It is calculated by dividing total revenue by the number of orders. A high AOV indicates that customers are buying more or purchasing higher-value products.
2. Profitability KPIs
Net profit margin
Measures the difference between revenue and costs, including Amazon fees. A high margin indicates a business that is sustainable in the long term.
ROAS (Return On Advertising Spend)
This KPI measures the return on investment in Amazon advertising. A positive ROAS indicates that the advertising strategy is working and generating revenue.
Customer acquisition cost (CAC)
Indicates how much it costs to attract a new customer through advertising and marketing. Reducing this cost improves business profitability.
3. Product KPIs
Product return rate
Reflects the percentage of returned orders and the reasons behind them. A high number may indicate issues with quality, customer expectations, or delivery times.
Sales ranking (BSR – Best Seller Rank)
Indicates a product's position within its category. A low BSR means the product sells well.
Available stock and inventory turnover rate
Monitors the amount of product available and the speed at which it sells. It also helps prevent stockouts or excess inventory.
4. Customer service KPIs
Customer response rate
Average response time to user questions. A short response time improves customer trust and can increase sales.
Average product rating
This KPI measures the average rating of a product based on customer product reviews . A high score is key to attracting more buyers.
Order Defect Rate (ODR)
Measures issues with orders, such as cancellations or returns. A high ODR can affect the business reputation and the seller account.
5. Logistics KPIs
Delivery time and order fulfillment
Indicates the average time it takes for an order to reach the customer. Fast shipping improves the user experience and platform ranking.
On-time shipping rate
Especially relevant for FBM sellers, it measures the number of orders shipped within the estimated time.
Amazon storage cost
For FBA sellers, this KPI measures the cost of keeping products in Amazon warehouses. Optimizing inventory reduces unnecessary costs.
Key differences between KPIs in FBA and FBM
FBA (Fulfillment by Amazon)
Sellers operating under the FBA model rely on Amazon's platform to manage their inventory, storage, and shipments. This involves additional logistics costs, but allows for greater delivery efficiency.
Among the most relevant KPIs on Amazon for this model are:
- Storage time and stock turnover, since Amazon charges for the space used.
- Order Defect Rate (ODR), which impacts customer satisfaction.
- Storage cost, key to maintaining business profitability.
FBM (Fulfillment by Merchant)
In FBM, sellers manage their own logistics, including storage, order preparation, and shipping. This gives greater control, but requires process optimization.
The most important KPIs include:
- Delivery time and fulfillment rate, essential to avoid delays.
- Shipping costs, which directly impact profitability.
- Customer satisfaction, measured by ratings and response times.
Both models have advantages and challenges, so choosing the right one depends on the type of products and business goals.
