How are Amazon KPIs Useful?

Amazon is considered one of the largest and most complex e-commerce platforms globally. It provides sellers with strong analytical tools, global selling choices, and multi-channel fulfillment options.

Amazon KPIs are integral to almost every online enterprise. In simple terms, Amazon KPIs help measure progress over a specific timeframe against set standards.

Top KPIs that Amazon Uses to Track Growth

Tracking these straightforward yet significant Amazon KPIs is essential for managing the growth of your digital market. Achieve sustainable growth, maintain competitiveness, and measure all facets of the marketplace.

These Amazon KPIs help sellers and the platform track sales performance, customer satisfaction, inventory status, and operational efficiency.

By understanding and monitoring these critical Amazon performance metrics, sellers can make data-informed decisions to enhance their strategies and boost business growth.

1: Sales Revenue

You must start the list by discussing the KPI with the most significant impact on your profits.
A company lacking sales is a failing company. Monitoring sales provides a swift overview of your Amazon business's performance.

A consistent rise in sales income signifies favorable growth. If you are wondering how to calculate sales revenue over a set period, it is vital to implement KPIs.

Without understanding the reasons for changes in sales revenue, creating an effective marketing or sales promotion strategy becomes significantly harder.

2: Return on Ad Spend

Return on Advertising Spend, or ROAS, is also referred to as ROAS. It is effective to allocate a portion of the budget to marketing and advertising efforts. Understanding and foresight are required to prevent advertising expenses from escalating out of control.

Extra Ad Spend results in increased sales. High ACoS (Advertising Cost of Sales) eats into your profits and, if left unchecked, can lead to serious financial consequences.

You would want an excellent return on advertising expenditure. Some Amazon sellers can achieve 2x, 4x, or even 10x ROAS, and the best way to monitor this is to use KPIs.

Amazon advertising has increasingly become expensive. Evaluating success solely through campaign metrics, such as Advertising Cost of Sales (ACoS), fails to provide a comprehensive overview. Thus, Total Advertising Cost of Sale (TACoS) is considered to be more relevant.

TACoS measures advertising expenses relative to your overall sales. It defines the impact of your advertisements on your total revenue and sustained brand vitality. Lower TACoS directly increases organic sales, reducing your dependence on paid traffic.

TACoS offers a broad perspective by considering organic revenue alongside ad-attributed revenue. It is a more effective measure of whether your ads are fostering sustainable growth rather than achieving short-term success.

3: Inventory

Some sellers do not view inventory management as a key performance indicator on Amazon. Variations in sales speed and product seasonality can lead to unforeseen OOS (Out of Stock) occurrences. This may adversely impact your product’s Best Seller Rank.

As a seller, your time and energy are precious, so spend them on conventional inventory management methods, such as maintaining and revising spreadsheets. Thus, efficient inventory management reduces storage costs and helps maintain high product availability. It is effective for growth on Amazon.

4: Ratings and Reviews

Everyone knows that Amazon is among the most consumer-focused e-commerce firms globally. At the start of 2021, approximately 142 million Amazon customers held Prime memberships. It imposes significant penalties on sellers who fail to meet its quality standards.

Regardless of compliance policies, items that receive poor ratings and negative reviews quickly drop in rankings and disappear.

Amazon tracks product return rates to monitor customer satisfaction and product quality. High return rates negatively affect seller performance and search visibility.

5: Click-Through Rate

The Click-Through Rate (CTR) is the percentage of people who click your advertisement.

If 100 individuals view your listing and 3 click it, you would achieve a CTR of 3%. This Amazon KPI is closely associated with Return on Ad Spend and is among the key Amazon KPIs. If PPC is the primary marketing channel, CTR serves as its performance metric.

You can determine the Amazon CTR for a specific product by downloading the Search Term Report and finding out the effectiveness of ads, content, and targeted keywords; although the task is somewhat cumbersome.

You can download the Search Term Report to evaluate ad, content, and targeted keyword performance and assess the product's CTR.

On the other hand, conversion rate measures how many clicks result in actual sales. Amazon's algorithm focuses on listings having high conversion rates, showing relevance and customer satisfaction.

The Amazon conversion rate is the number of people who make a purchase immediately after seeing your product listing. Understanding that figure will help you identify potential obstacles impacting your sales.

Prioritize high-quality images, detailed product descriptions, attractive pricing, and favorable reviews to enhance conversion rates. Carefully optimize CTR and conversion rates to improve your product's performance and total sales.

6. Best Seller Rank

Best Seller Rank (BSR) is one of the most crucial Amazon Key Performance Indicators for tracking product performance, including sales velocity and market appeal. It is an essential indicator that informs sellers about their product's sales performance relative to other competitors.

The Amazon Best Sellers lists highlight the highest-selling items in specific categories, ranked by BSR scores. The Amazon Best Sellers Rank does not directly influence sales. Analyzing BSR scores provides excellent product ideas and monitors sales patterns, and you can incorporate them into your selling approach.

7: Customer Performance

Whether online or offline, a business’s value is determined by how its customers perceive it. The upcoming customer feedback situations can become disastrous if not addressed promptly, including -

   • A-Z Guarantee claims
   • Customer chargeback
   • Negative reviews
   • Late Shipment Rate (for FBM sellers)
   • Prolonged Customer Response Time (Responding 24 hours after a customer leaves a message)

If the percentage meter for any of these factors begins to rise, Amazon will promptly issue notifications and may even suspend the account. KPIs such as Order Defect Rate (ODR), late shipment rate, and customer feedback score are monitored closely. A low ODR and a high positive feedback signal enhance performance and customer trust.

8. Amazon Seller Fees

The Fulfillments by Amazon (FBA) system draws a vast number of sellers to establish their businesses on Amazon. In this method, Amazon manages the picking, packing, and shipping aspects of online sales.

It includes referral fees, FBA fees, closing fees, and any other charges Amazon deducts from each sale. By closely monitoring seller fees as part of your Amazon KPI dashboard, you can identify opportunities to optimize your listings, adjust pricing strategies, or switch fulfillment methods to reduce costs.

9. Impressions and Viewable Impressions

On Amazon, impressions and viewable impressions are digital marketing metrics. It helps measure how frequently your content, such as advertisements, product links, or sponsored materials, appears to users.

An impression is registered each time your content is displayed on a user's screen. For instance, when your advertisement appears in search results or on a product detail page, it is considered one impression. It helps you understand the fundamental reach and potential visibility of your content on Amazon.

A visible impression is a more effective indicator as it only matters when your content is displayed in a spot on the user's screen.  According to Amazon's viewability criteria, at least 50% of the ad must be visible for at least 1 second. It increases the chance that the user will see the impression. It is a more significant indicator of visibility compared to raw impressions.

How Do You Measure Amazon KPIs?

Numerous KPIs must be considered, irrespective of product type or niche. Listing all of them would still require you to possess at least a fundamental understanding of finance, accounting, and inventory management to understand the data.

The following are three KPI for Amazon that serve as the foundation for any product-oriented business:

   • Sales
   • Profitability
   • Inventory Management

To gain clearer insight into the intricacies of assessing Amazon KPIs, consider profitability as a case in point. As a seller, you must determine the profit from each product listing each month.

You must consider one or more of the subsequent expenses, like -

   • Referral Fee
   • FBA Fee
   • Tax
   • Shipping Tax
   • Fixed and Variable Closing Fee
   • Sales Tax Service Fee
   • High-Volume Listing Fee
   • Shipping Holdback Fee
   • Storage Fee

It is not possible to manually consider every metric used to evaluate your product. Automating the complete process with a top-tier Amazon seller dashboard makes selling on Amazon simpler and more efficient.

6. Identify Correlations and Root Causes

You must delve deeper into numerical data and explore how various KPIs interact with one another. A decrease in the Buy Box percentage may be associated with higher prices or reduced inventory. Understanding these connections enables you to implement specific enhancements.

7. Take Action and Monitor Results

How To Create and Define a KPI?

Developing a valuable KPI involves several steps. Here are some guidelines to help you initiate that process for your business goals.

2. Determine a key metric

You can choose a performance metric to assess and advance toward those goals. Ensure consideration of both external performance (e.g., sales) and internal performance (e.g., employee engagement).

3. Make it measurable

It is essential to understand how you will assess success or failure based on the KPI. Define exactly how you will track progress and determine whether you’ve succeeded or fallen short. You must focus on the improvement you want to achieve in this metric and set a realistic deadline for reaching your target. Making the KPI measurable creates a benchmark for success and ensures accountability in your business strategy.

4. Keep track of it

Set a proper schedule for monitoring the KPI. If your timeline is one year, you can opt for monthly or bi-monthly updates. For marketing KPIs, implementing reporting or analytical tools, such as Amazon Attribution, helps track your progress.

After completing this process and establishing various KPIs, you must develop a KPI dashboard that provides a consolidated view of your progress.
