6 Essential Amazon Seller Metrics You Need to Monitor for Success

Monitoring the right metrics can make or break your success on Amazon. Understanding the 6 essential Amazon seller metrics is crucial for any e-commerce business aiming for the top. Metrics such as sales performance, inventory health, and customer satisfaction play vital roles in providing insights that guide your strategic decisions. Let’s dive deeper into these critical areas and discover how they can impact your Amazon journey.

1. Sales Performance Metrics

Sales performance metrics are pivotal for any Amazon seller aiming to gauge their success on the platform. These metrics offer insights into how well your products are selling and how effective your sales strategies are.

Gross Sales: This is the total revenue generated before any deductions such as returns, shipping fees, and taxes. It gives a top-level view of your sales performance.

Net Sales: Unlike gross sales, net sales deduct returns, discounts, and allowances. It provides a more accurate representation of your actual sales revenue.

Units Sold: Tracking the number of units sold helps you understand the demand for each product. This data can guide inventory management and marketing efforts.

Average Sales Price (ASP): This metric indicates the average selling price of your products. You can calculate it by dividing total sales revenue by the number of units sold. ASP helps identify pricing trends and informs pricing strategies.

Sales Growth: Compare your sales over different periods to track growth. Month-over-month or year-over-year comparisons can highlight trends and seasonality, helping you plan for peak periods.

Sales Rank: Amazon assigns a sales rank to products based on their sales performance. A lower rank indicates better performance compared to products in the same category. Monitoring sales rank helps assess product popularity and competitiveness.

2. Inventory Health Metrics

2. Inventory Health Metrics

Monitoring your inventory health is critical for maintaining a profitable Amazon business. This involves evaluating various metrics to ensure you have optimal stock levels, minimize storage fees, and avoid stockouts or overstock situations.

Inventory Turnover

Inventory turnover measures how often your inventory is sold and replaced over a period. A high turnover rate indicates that products are moving quickly, while a low rate suggests slow-moving stock that could lead to additional storage costs.

Aging Inventory

This metric tracks the age of your inventory. Products that sit in your warehouse for too long can incur long-term storage fees, so it’s important to monitor and manage your aging inventory effectively.

FBA Storage Fees

Fulfilled by Amazon (FBA) sellers should pay close attention to storage fees, which can add up if inventory is not managed properly. Regularly assessing these fees can provide insights on whether to sell through struggling products at a discount.

Stock Availability

Ensuring you have enough stock to meet demand without overstocking is a balancing act. Utilize tools and strategies to predict sales trends and restock inventory efficiently, maintaining a healthy balance.

Stranded Inventory

Products that are not active due to listing errors or other issues are considered stranded inventory. Regularly check and resolve such issues to ensure all inventory is available for sale.

3. Customer Satisfaction Metrics

Customer satisfaction is pivotal for any Amazon seller aiming to gain a loyal client base and ensuring repeat business. Here are several key metrics to monitor to gauge customer satisfaction:

1. Customer Feedback and Ratings

Keep track of the feedback and ratings left by customers. High ratings and positive feedback indicate that customers are satisfied with the product and the service they received. Responding to reviews—both positive and negative—demonstrates your commitment to customer satisfaction.

2. Product Reviews

Product reviews provide valuable insights into customer satisfaction. Look for common themes in the reviews to identify areas for improvement. Responding to negative reviews and addressing customer concerns publicly can help resolve issues and improve overall satisfaction.

3. Net Promoter Score (NPS)

The Net Promoter Score (NPS) is a powerful metric used to measure customer loyalty and satisfaction. By asking customers how likely they are to recommend your product or service on a scale of 0-10, you can categorize them into promoters, passives, and detractors. Aim to increase the percentage of promoters.

4. Return and Refund Rates

A high return or refund rate may indicate dissatisfaction with the product. Analyze return reasons to identify common issues and make improvements. Ensuring clear product descriptions and quality control can help reduce these rates.

5. Customer Service Response Time

Timely responses to customer inquiries and issues are crucial for maintaining satisfaction. Monitor your response times and aim to provide prompt and helpful responses. This can significantly improve the customer experience and satisfaction.

Product page views and traffic are crucial for any Amazon seller aiming to increase their sales. High traffic to your product pages can significantly boost the visibility of your items, leading to potential sales increases.

Analyzing Traffic Sources

Amazon provides various reports that detail traffic sources. These reports help in understanding whether your traffic is coming from organic searches within Amazon, external advertising, or other sources. Use this data to refine your marketing and advertising strategies.

Improving Product Listings

To maximize page views, ensure that your product listings are fully optimized. This involves using high-quality images, detailed and keyword-rich descriptions, and competitive pricing. The better your listings, the more likely they are to attract viewer interest and clicks.

Monitoring Key Metrics

Keep a close eye on metrics such as Click-Through Rate (CTR) and Average Session Duration. A high CTR indicates that your product listings are appealing and relevant to customers’ search queries. Average Session Duration can help you understand how long potential buyers are staying on your product pages, giving insights into the effectiveness of your content.

Enhancing User Experience

Improving the overall user experience on your product pages can lead to more traffic and higher engagement. Ensure that your pages load quickly, are mobile-friendly, and provide all the information that a potential buyer may need. Addressing customer reviews and questions promptly can also enhance the user experience.

Leveraging Social Proof

Product reviews and ratings significantly impact page views. New customers often rely on the experiences of previous buyers. Encourage satisfied customers to leave positive reviews to boost your product’s credibility and attractiveness.

Order Defect Rate (ODR)

The Order Defect Rate (ODR) is a critical metric that measures the quality of your customer service. Maintaining a low ODR is essential as it can directly impact your ability to sell on Amazon. An ODR is composed of three main components:

  • A-to-Z Claim Rate: The percentage of orders with A-to-Z guarantee claims.

Perfect Order Percentage (POP): This KPI indicates the percentage of orders that are shipped on time, arrive undamaged, and contain the correct items. Higher POP values signify superior fulfillment performance.

Late Shipment Rate: This measures the percentage of orders shipped after the expected ship date. Keeping this rate low is essential as it directly affects your seller performance metrics and ranking.

Pre-Fulfillment Cancel Rate: This tracks the percentage of orders canceled by you before they are shipped. A high cancel rate can indicate stock management issues or problems with order processing systems.

Tracking Information Accuracy: Accurate tracking information must be provided to customers to ensure transparency and reliability in the delivery process. This also helps in monitoring parcel movements and managing customer queries efficiently.

To improve your Seller Rating Score, focus on providing exceptional customer service, addressing any issues promptly, and meeting delivery expectations.

Promotional metrics play a crucial role in evaluating the effectiveness of your marketing campaigns on Amazon. Careful monitoring can help you determine which promotional strategies resonate with your audience and drive sales.


Impressions indicate the number of times your promotional content appears in search results, product detail pages, and other areas of the Amazon platform. Tracking impressions helps you understand the reach of your promotional activities and how often potential customers are seeing your advertisements.


Clicks are a direct indicator of customer interest. When someone clicks on your promotional content, it means they are interested enough to learn more about your product. Analyzing click data allows you to gauge the attractiveness of your promotions and optimize ad creatives for better engagement.

Return on Advertising Spend (ROAS)

ROAS measures the revenue generated from your promotional spend. It is calculated by dividing the total revenue by the total ad spend. ROAS provides a clear picture of the effectiveness of your promotional investments, helping you optimize your budget allocation.
