Amazon Seller Metrics: KPIs, Targets & Tracking Guide (2026)

published on 28 August 2026

Amazon seller metrics show whether your account is healthy and whether sales, traffic, advertising, inventory, and offers are performing as expected. The most important metrics fall into five core groups: account health, sales and traffic, advertising, inventory, and customer or offer performance. 

Eligible advertisers can also track brand and acquisition metrics as a supplemental layer. Start with policy-critical metrics such as Account Health Rating, Order Defect Rate, and applicable seller-fulfilled shipping metrics, then use conversion, ad efficiency, inventory, and Featured Offer signals to diagnose business performance. 

This guide focuses on Amazon Seller Central for Amazon.com sellers; Vendor Central uses different reports, terms, and processes.

Amazon Seller Metrics at a Glance

Begin with account health metrics since they can cause serious sales problems. Then, review sales, traffic, advertising, inventory, offers, and customer acquisition metrics in order of urgency.

Metric Family What It Tells You Policy Target? Typical Location Review Priority
Account health Whether your account or seller-fulfilled offers are at risk Yes, for some Amazon metrics Account Health Immediate or daily alerts
Sales and traffic Changes in revenue, demand, traffic, and conversion No universal target Business Reports Weekly
Advertising How ads are being delivered and how efficiently they perform No universal target Campaign Manager and Amazon Ads reports During campaigns and weekly
Inventory Stock availability, aging, sell-through, and FBA inventory health Program-dependent Inventory and FBA tools Daily alerts plus weekly review
Offer and customer Featured Offer, returns, feedback, and customer signals Mixed Business Reports, Account Health, and feedback tools Weekly; immediate for policy issues
Brand and acquisition Brand performance and new-customer growth No universal target Amazon Ads and Brand Metrics Monthly or by campaign cycle

Amazon Seller Metrics Scorecard: What to Track First

A good Amazon seller scorecard separates policy metrics from regular business KPIs.

Policy metrics can impact your account health or seller-fulfilled offers. Business KPIs show what is happening with your sales, traffic, ads, inventory, and customers.

Use this scorecard to get started.

Metric Family Target Type Applies To FBA / FBM Typical Location Review Cadence Recommended Action
Account Health Rating Account health Policy/account risk All sellers Both Account Health Immediate/daily Review policy issues and required actions.
Order Defect Rate Account health Amazon policy target Relevant seller orders Both, where applicable Account Health Immediate/daily Find the orders and defect type causing the increase.
Late Shipment Rate Fulfillment Amazon policy target Seller-fulfilled orders FBM Account Health Daily Review handling and shipping processes.
Pre-fulfillment Cancellation Rate Fulfillment Amazon policy target Seller-fulfilled orders FBM Account Health Daily Check inventory accuracy and fulfillment capacity.
Valid Tracking Rate Fulfillment Policy/program-dependent Applicable seller-fulfilled orders FBM Account Health Daily Check carrier and tracking problems.
On-Time Delivery Rate Fulfillment Policy/program-dependent Seller-fulfilled orders FBM Account Health Daily Review delivery and carrier performance.

Before you act on any metric, ask one simple question:

Is this an Amazon policy target or a business-performance KPI?

Policy problems usually need quick action. For business KPIs, get more context before changing pricing, ads, inventory, or listings.

Account Health and Fulfillment Metrics

Start with account-health metrics because they can affect your ability to sell on Amazon.

Amazonโ€™s Account Health dashboard highlights policy issues, customer service, and shipping problems. If you fulfill orders yourself, these metrics are even more important since you handle shipping and tracking.

Current Amazon Account Health Targets to Watch

Some Amazon metrics have clear public targets. Others depend on your account, program, or shipping setup.

Use the table below as a guide, but always check the latest US Seller Central rules before making important decisions.

Metric Current Public Guidance Applies To Why It Matters Source Checked
Order Defect Rate Keep below 1% Relevant seller orders High ODR can put selling privileges at risk Amazon US guidance reviewed August 2026
Late Shipment Rate Keep below 4% Seller-fulfilled orders Poor performance can affect seller-fulfilled offers Amazon US guidance reviewed August 2026
Pre-fulfillment Cancellation Rate Keep below 2.5% Seller-fulfilled orders High cancellations can point to inventory or fulfillment problems Amazon US guidance reviewed August 2026
Valid Tracking Rate Check the current requirement for your account or program Applicable seller-fulfilled orders Requirements can change by shipping setup or program Verify in current US Seller Central
On-Time Delivery Rate Check the current requirement for your account or program Seller-fulfilled orders Shows delivery reliability Verify in current US Seller Central
Account Health Rating Use current Account Health status and score All sellers Shows account-policy risk Amazon US guidance reviewed August 2026

Account Health Rating

Account Health Rating (AHR) is Amazon's 0โ€“1,000 policy-compliance score designed to help sellers understand their risk of account deactivation.

Do not treat AHR as a regular growth metric. If sales drop, investigate, but if you get a serious Account Health warning, act right away.

Check Account Health for:

  • active policy violations,
  • customer-service issues,
  • shipping-performance problems,
  • unresolved notifications,
  • required actions,
  • changes in overall account status.

Order Defect Rate

Order Defect Rate (ODR) is the percentage of orders with specific customer-order problems.

Amazonโ€™s public US guidance reviewed in August 2026 says sellers should generally keep ODR below 1%. Check the latest Seller Central policy before publishing or making major account decisions.

ODR can include problems such as:

  • certain negative seller feedback,
  • qualifying A-to-z Guarantee claims,
  • chargebacks.

If your ODR goes up, find out which orders are causing the issue.

Ask:

  • Are several problems connected to the same SKU?
  • Is fulfillment causing the issue?
  • Are customers receiving the wrong product?
  • Is the listing creating the wrong expectations?
  • Are customers repeating the same complaint?

The goal is not just to lower the percentage. You need to fix the underlying cause.

Late Shipment Rate

Late Shipment Rate (LSR) primarily applies to seller-fulfilled orders.

Amazonโ€™s public US guidance, reviewed in August 2026, states that seller-fulfilled LSR should remain below 4%. Check the current requirement before publication.

If LSR increases, review:

  • handling-time settings,
  • warehouse processing time,
  • order cut-off times,
  • carrier pickups,
  • shipment confirmation.

Do not use LSR to measure FBA shipping performance, since Amazon handles shipping for FBA orders.

Pre-Fulfillment Cancellation Rate

Pre-Fulfillment Cancellation Rate shows the percentage of seller-fulfilled orders you cancel before shipment.

Amazonโ€™s public US guidance, reviewed in August 2026, states that this rate should remain below 2.5% for seller-fulfilled orders.

A higher cancellation rate can mean:

  • inventory counts are wrong,
  • inventory is not syncing properly,
  • products are showing as available when they are actually out of stock,
  • your team cannot fulfill all orders on time.

If cancellations rise, check your inventory accuracy first.

Valid Tracking Rate

Valid Tracking Rate (VTR) indicates whether you are providing Amazon with valid tracking details for applicable seller-fulfilled orders.

Do not assume the same VTR target applies to every seller or program.

Check:

  • whether the carrier is supported,
  • whether the tracking number is correct,
  • whether tracking is added on time,
  • whether your warehouse system is sending the right data,
  • what Seller Central currently shows for your account.

On-Time Delivery Rate

On-Time Delivery Rate, or OTDR, is another important metric for seller-fulfilled orders.

If OTDR drops, check:

  • carrier performance,
  • handling time,
  • shipping-service selection,
  • promised delivery dates,
  • processing delays.

Use your current Amazon.com Account Health dashboard as the final source for the requirement that applies to your account.

Seller Feedback and Product Reviews Measure Different Things

Seller feedback and product reviews measure different things.

Seller feedback is about the customerโ€™s experience with the seller and order. Product reviews are about the customerโ€™s experience with the product.

Do not combine them into one metric.

Seller feedback can affect seller performance. Product reviews can help you understand product quality, customer expectations, and conversion.

If you ask customers for reviews, use Amazon-approved methods such as the Request a Review feature. Do not offer rewards or ask only happy customers to leave positive reviews.

FBA vs. FBM Seller Performance Metrics

FBA and FBM sellers do not use every metric in the same way.

Metric FBA FBM / Seller-Fulfilled
Account Health Rating Yes Yes
Order Defect Rate Monitor where applicable Yes
Late Shipment Rate Not an FBA shipping metric Yes
Pre-fulfillment Cancellation Rate Not for Amazon-fulfilled orders Yes
Valid Tracking Rate Not an FBA shipping metric Yes, where applicable
On-Time Delivery Rate Not an FBA shipping metric Yes, where applicable
Inventory Performance Index Relevant to FBA inventory No as an FBA inventory score
Sales and traffic metrics Yes Yes
Featured Offer % Yes Yes
Advertising metrics If advertising If advertising

The rule is simple:

Use each metric only for the fulfillment model it is meant to measure.

If account-health problems become serious, see SalesDuoโ€™s guide to Amazon seller account suspension.

Sales, Traffic, Conversion, and Offer Metrics

Sales tell you what happened, but they do not always explain why.

To understand a change in performance, look at sales, traffic, conversion, and Featured Offer data together.

Ordered Sales

Ordered sales show the value of orders placed during a selected period.

Do not judge sales from one number alone. Look at the trend.

Compare:

  • week over week,
  • month over month,
  • year over year when seasonality matters,
  • one product against another,
  • actual sales against your target.

If sales fall, check other metrics before making any changes.

Sales can fall because of:

  • fewer sessions,
  • lower conversion,
  • stock shortages,
  • lower Featured Offer share,
  • weaker advertising,
  • pricing changes,
  • seasonality.

For deeper analysis, see SalesDuoโ€™s guide to analyzing Amazon sales data.

Units Ordered

Units ordered help you understand whether revenue changed because you sold more products or because prices changed.

For example:

Revenue up, units flat: Your average selling price or product mix may have increased.

Units up, revenue flat: Your average selling price or product mix may have decreased.

Revenue and units both down: Check traffic, conversion, availability, and offer performance.

Sessions and Page Views

Sessions show whether shoppers are visiting your product pages.

Page Views show the total number of views of your product detail pages during the selected period and can include multiple views within a single session.

If sales change, check traffic early.

Pattern What It May Mean First Area to Check
Sessions โ†“, conversion stable Traffic problem Visibility, ads, demand
Sessions stable, conversion โ†“ Conversion problem Offer, price, listing, reviews
Sessions โ†‘, sales flat Traffic is not converting Offer and detail page
Sessions and conversion stable, sales โ†“ Another operating issue Availability, mix, Featured Offer
Featured Offer % โ†“ Offer problem Pricing, eligibility, fulfillment

This helps you avoid fixing the wrong problem.

If traffic is falling, rewriting the product page may not fix the main issue. If traffic is stable but conversion is falling, spending more on ads may only send more people to a weak offer.

Unit Session Percentage and Conversion

Unit Session Percentage shows how well product-page traffic turns into orders.

Use it as a signal, not a universal target.

Conversion can change based on:

  • category,
  • price,
  • traffic source,
  • brand strength,
  • promotions,
  • season,
  • competition.

The best comparison is often the productโ€™s own past performance.

If conversion drops, review:

  • price,
  • Featured Offer,
  • availability,
  • listing content,
  • images,
  • reviews,
  • competing offers,
  • promotions.

Featured Offer Percentage

Amazon now often uses the term Featured Offer for what many sellers still call the Buy Box.

Featured Offer percentage shows how often your eligible offer wins the main purchase position.

A drop can be linked to:

  • price,
  • inventory,
  • fulfillment,
  • seller performance,
  • offer eligibility,
  • competitive changes.

Do not assume the cause just by looking at the percentage.

For deeper analysis, see SalesDuoโ€™s Buy Box analytics and strategy guide.

For percentage and eligibility questions, see Buy Box percentage and eligibility.

Returns and Refunds

Returns and refunds can show problems that sales numbers may hide.

Review:

  • return rate by ASIN,
  • refund volume,
  • return reasons,
  • repeated customer complaints,
  • changes after listing updates,
  • changes after product updates.

A product can grow in sales and still perform poorly if returns increase.

Advertising Efficiency Metrics

Advertising metrics show whether your paid traffic is reaching shoppers and producing useful results.

Do not judge ad metrics alone. Compare them with sales, conversion, and profit margin.

Impressions

Impressions tell you how often shoppers saw your ad.

A drop in impressions can happen because of:

  • lower bids,
  • limited budget,
  • targeting changes,
  • lower search demand,
  • campaign changes,
  • eligibility problems.

Impressions show ad delivery. They do not show whether the campaign is profitable.

Clicks and Click-Through Rate

Clicks show how often shoppers click your ads.

CTR shows the percentage of ad impressions that became clicks.

CTR = Clicks รท Impressions ร— 100

CTR helps you understand whether your ad is getting attention.

But always check conversion too.

High CTR + low conversion may mean shoppers are interested enough to click, but the product page or offer is not compelling enough to drive a purchase.

Cost Per Click

CPC is the average amount you pay per ad click.

Do not judge CPC by cost alone. Compare it with conversion, ACoS, ROAS, and margin.

Conversion Rate

Advertising conversion rate shows how well ad traffic turns into orders or other defined conversions.

The exact formula can vary by report and traffic source, so check the current definition in Amazon Ads or Seller Central before comparing dashboards.

A falling conversion rate can point to:

  • a weak offer,
  • pricing changes,
  • poor product-page content,
  • lower review quality,
  • poor targeting,
  • stronger competitors.

Do not judge ad conversion alone. Compare it with CTR, CPC, ACoS, ROAS, Featured Offer status, and the productโ€™s overall conversion trend.

Advertising Cost of Sales

Advertising Cost of Sales (ACoS) compares ad spend to ad-attributed sales.

ACoS = Ad spend รท Ad-attributed sales ร— 100

If you spend $10,000 and generate $50,000 in ad-attributed sales:

ACoS = 20%

There is no single โ€œgoodโ€ ACoS for every Amazon seller.

Compare ACoS with:

  • contribution margin,
  • product stage,
  • campaign goal,
  • organic sales,
  • repeat-purchase value.

For benchmark context, use SalesDuoโ€™s Amazon advertising benchmarks guide.

Return on Ad Spend

ROAS shows how much ad-attributed revenue you make for every dollar spent on ads.

ROAS = Ad-attributed sales รท Ad spend

Using the same example:

  • Ad spend = $10,000
  • Ad-attributed sales = $50,000

ROAS = 5.0

ACoS and ROAS show the same relationship in two different ways.

A 20% ACoS equals a 5.0 ROAS.

Total Advertising Cost of Sales

TACoS compares ad spend with total Amazon sales, not only ad-attributed sales.

TACoS = Ad spend รท Total sales ร— 100

For example:

  • Ad spend = $10,000
  • Ad-attributed sales = $50,000
  • Total sales = $100,000

The account has:

  • ACoS = 20%
  • ROAS = 5.0
  • TACoS = 10%

None of these numbers is automatically good or bad.

Compare them with:

  • profit margin,
  • growth goal,
  • product stage,
  • organic performance,
  • past trends.

For deeper campaign work, see SalesDuoโ€™s Amazon PPC strategy guide.

Advertising Formula Summary

Metric Formula What It Tells You
CTR Clicks รท impressions ร— 100 How often an impression becomes a click
Conversion rate Conversions or orders รท relevant traffic base ร— 100 How well traffic becomes conversions; confirm the report definition
ACoS Ad spend รท ad-attributed sales ร— 100 Ad spend as a share of attributed sales
ROAS Ad-attributed sales รท ad spend Attributed revenue per ad dollar
TACoS Ad spend รท total sales ร— 100 Ad spend compared with total Amazon sales

Use these formulas to understand performance. Do not use them as fixed targets for every seller.

Inventory Health Metrics

Inventory metrics help you avoid two major problems: running out of stock and holding too much stock.

Too little inventory can stop sales. Too much inventory can lock up cash and increase storage costs.

Inventory Signal What It Can Tell You First Action
Stockout Customers cannot buy because the product is unavailable Check replenishment and inbound inventory
Low sell-through Inventory may be moving too slowly Review demand, traffic, conversion, and stock level
Very high sell-through The product may sell out before more stock arrives Review forecast and reorder timing
Aging inventory Cash is tied up in slow-moving products Review demand, pricing, promotions, and future orders
Stranded inventory Units exist but cannot currently be sold Fix the listing or offer issue
Excess inventory Stock is higher than expected demand Reduce unnecessary replenishment and review demand

Inventory Performance Index

The Inventory Performance Index (IPI) is an FBA inventory-efficiency metric.

Use it as a health signal, but do not rely on a single permanent โ€œgood IPI score.โ€

Amazon can change its programs and related thresholds.

Check Seller Central for current information when a specific threshold matters.

Sell-Through

Sell-through shows how quickly your inventory is selling.

Low sell-through can point to:

  • weak demand,
  • too much stock,
  • low traffic,
  • poor conversion,
  • pricing problems,
  • seasonality.

Very high sell-through can also create a problem if you sell out before you can restock.

Inventory Age

Inventory age shows how long products have been sitting in stock.

Older inventory can create:

  • higher storage costs,
  • cash-flow pressure,
  • markdown risk,
  • less flexibility.

Do not only ask how many units you have.

Also ask:

How old is the inventory, and how quickly is it selling?

In-Stock Rate and Stockouts

Stock availability should be watched closely.

If an important ASIN goes out of stock, it can affect:

  • sales,
  • ads,
  • customer availability,
  • conversion data,
  • replenishment plans.

Set alerts for your important products.

Stranded Inventory

Stranded inventory means you have stock that cannot currently be sold due to a listing or offer issue.

Check stranded inventory regularly so sellable products do not stay unavailable.

Excess Inventory

Excess inventory means you have more stock than demand currently needs.

Review:

  • sales velocity,
  • sell-through,
  • inventory age,
  • demand forecast,
  • promotions,
  • replenishment plans.

For deeper forecasting and replenishment, see SalesDuoโ€™s Amazon inventory management guide.

Brand and Customer Acquisition Metrics

Brand and acquisition metrics help you understand whether your campaigns are bringing in new customers and driving your brand's growth.

Keep these metrics separate from normal seller and advertising performance metrics.

Amazon Brand Metrics

Amazon Brand Metrics can help eligible advertisers understand how shoppers interact with a brand during the buying journey.

It can give more information about:

  • awareness,
  • consideration,
  • purchase behavior,
  • category-level brand performance.

For deeper coverage, use SalesDuoโ€™s Amazon Brand Metrics guide.

New-to-Brand Metrics

New-to-Brand metrics help advertisers understand whether customers are buying from the brand for the first time on Amazon within Amazonโ€™s measurement window.

These metrics are useful when your goal is to bring in new customers, not just make immediate sales.

Two campaigns may generate similar sales but bring in very different numbers of new customers. That can change how valuable each campaign is to your business.

Seller, Advertising, and Brand Metrics Are Different

Metric Family Main Question
Seller performance metrics Is the account healthy and running well?
Advertising metrics Are paid campaigns giving the expected result?
Brand/acquisition metrics Are we reaching and gaining new customers?

Do not use one type of metric to answer every business question.

Where to Find Each Metric in Seller Central and Amazon Ads

Account Health Overview
Account Health Overview

Amazon seller data is spread across different tools.

You may need Account Health for policy issues, Business Reports for sales and traffic, Amazon  Ads for campaign data, inventory tools for FBA performance, and Payments reports for financial activity.

Metric / Family Typical Location What to Look For
AHR and policy issues Account Health Compliance status and required actions
ODR Account Health Customer-service performance
LSR Account Health Seller-fulfilled shipping performance
Cancellation Rate Account Health Seller-fulfilled cancellations
VTR/OTDR Account Health/shipping performance Applicable fulfillment performance
Ordered sales Business Reports Revenue trend
Units Business Reports Order volume
Sessions Business Reports Detail-page traffic
Unit Session Percentage Business Reports Conversion signal
Featured Offer % Business Reports Offer performance
Impressions/clicks/CTR/CPC Campaign Manager/reports Ad delivery and traffic
ACoS/ROAS Campaign Manager/reports Ad efficiency
IPI Inventory/FBA tools FBA inventory efficiency
Inventory age Inventory tools Aging inventory
Stranded/excess inventory Inventory tools Availability and overstock problems
Brand Metrics/NTB Amazon Ads/Brand Metrics Brand and acquisition signals
Payments and settlement data Payments/transaction reports Fees, refunds, reimbursements, and settlement activity

Payment and settlement reports help you connect revenue with Amazon fees, refunds, reimbursements, and other transactions.

They do not replace Business Reports, but they are useful for understanding the financial side of seller performance.

If you need the deeper campaign setup and reporting workflow, see SalesDuoโ€™s guide to advertise on Amazon Seller Central.

Build an Amazon Seller Performance Dashboard

A good Amazon seller dashboard should turn scattered numbers into clear actions.

For every important metric, the dashboard should answer:

  1. What are we measuring?
  2. Is it an Amazon policy target or a business KPI?
  3. Where does the data come from?
  4. Who is responsible for it?
  5. How often should it be checked?
  6. What should trigger action?
  7. What happens next?

Clear ownership, simple definitions, and clear data sources also make seller-performance reporting easier for everyone on the team to understand.

Assign an Owner

Every important metric should have an owner.

Metric Area Possible Owner
Account Health Account manager/operations
Sales and traffic Marketplace manager
Conversion Marketplace/content team
Advertising PPC manager
Inventory Supply-chain/inventory manager
Returns Operations/product team
Featured Offer Marketplace/operations

The exact person will depend on your team.

The important thing is that someone owns the metric and takes action when needed.

Add the Data Source and Cadence

For every dashboard row, include:

  • metric name,
  • metric family,
  • policy or business classification,
  • FBA/FBM applicability,
  • data source,
  • owner,
  • review cadence.

This makes the dashboard easier to understand and use.

Set Alert Rules

An alert is not the same as a target.

Amazon policy targets should clearly be labeled as Amazon rules.

Label internal business alerts as your own operating rules.

For example, you may want an alert when:

  • sessions drop sharply,
  • an important ASIN goes out of stock,
  • conversion falls below its normal range,
  • Featured Offer share drops,
  • ad spend rises faster than sales,
  • returns increase quickly.

Do not present these internal alert levels as Amazon requirements.

Track Current Value, Previous Value, and Trend

A useful scorecard should show:

  • current value,
  • previous value,
  • trend,
  • target type,
  • diagnosis,
  • next action,
  • action owner,
  • due date.

Instead of opening multiple reports each time, your team can keep the current value, previous value, owner, problem, and next action in one place.

Create a Smaller Executive View

Business leaders usually do not need every small KPI.

Create a simpler view that shows:

  • account risk,
  • sales trend,
  • traffic,
  • conversion,
  • ad efficiency,
  • inventory availability,
  • profitability,
  • major customer issues.

Your operations team can use the full dashboard for deeper analysis.

If your data is spread across Account Health, Business Reports, Amazon Ads, inventory tools, and spreadsheets, the SalesDuo Business Intelligence Dashboard can help bring it into a single view.

How to Diagnose a Change in Amazon Seller Metrics

Do not change bids, prices, listings, or inventory just because one number changed.

Check the metrics in a simple order to find the real problem first.

1. Check Account Health

Start with account risk.

Ask:

  • Is there a new policy issue?
  • Did ODR change?
  • Is there a seller-fulfilled shipping problem?
  • Is Amazon asking you to take action?

Fix urgent account problems first.

2. Check Availability

Next ask:

Could customers actually buy the product?

Check for:

  • stockouts,
  • stranded inventory,
  • unavailable offers,
  • suppressed listings,
  • fulfillment problems.

If the product was not available, traffic and conversion numbers will not tell the full story.

3. Check Traffic

If the product was available, check sessions.

Sessions down + conversion stable usually points to a traffic or visibility problem.

Possible areas to check include:

  • ad delivery,
  • organic visibility,
  • seasonality,
  • search demand,
  • external traffic.

4. Check Featured Offer

If traffic looks normal, check the Featured Offer percentage.

A drop can reduce sales even when product-page traffic stays the same.

Review:

  • pricing,
  • eligibility,
  • inventory,
  • fulfillment,
  • seller performance,
  • competing offers.

5. Check Conversion

If sessions are stable and the product is available, check conversion.

Sessions stable + conversion down can point to:

  • price,
  • weak offer,
  • listing changes,
  • poor reviews,
  • stronger competition,
  • ended promotions,
  • product issues.

6. Check Advertising

Review:

  • impressions,
  • clicks,
  • CTR,
  • CPC,
  • conversion,
  • ACoS,
  • ROAS,
  • TACoS.

Use the pattern to decide what to check next.

Pattern Possible Direction
Impressions โ†“, CTR stable Delivery, bids, budget, demand
Impressions stable, CTR โ†“ Ad relevance
Clicks stable, conversion โ†“ Offer or product page
ACoS โ†‘ because CPC rose Traffic cost
Ad sales stable, total sales โ†“ Organic or total-business weakness
TACoS โ†‘ while ACoS stable Higher dependence on ads

These patterns point you toward a possible problem. They do not prove the exact cause.

7. Check Customer and Return Signals

Next, look at:

  • return reasons,
  • refunds,
  • product reviews,
  • seller feedback,
  • customer complaints.

Look for the same issue showing up in several places.

8. Check Profit and Economics

Finally, ask whether the result is actually profitable.

Measure contribution profit, not just revenue or ROAS.

Include:

  • sales,
  • COGS,
  • Amazon fees,
  • advertising,
  • promotion costs,
  • fulfillment,
  • returns,
  • inventory costs,
  • other relevant operating costs.

Higher revenue does not always mean better business performance.

Metric-to-Action Decision Flow

Decision Flow of Metric-to-Action
Decision Flow of Metric-to-Action

Use this order:

Account risk?

โ†’ Yes: fix the policy or fulfillment issue.

No account risk? Check availability.

โ†’ Product unavailable: fix stock or offer problems.

Product available? Check traffic.

โ†’ Traffic down: check visibility, demand, and ads.

Traffic stable? Check Featured Offer.

โ†’ Featured Offer down: check price, eligibility, and fulfillment.

Featured Offer stable? Check conversion.

โ†’ Conversion down: check the offer, listing, reviews, and product experience.

Conversion stable? Check advertising.

โ†’ Ad efficiency changed: check CPC, targeting, conversion, and margin.

Then check customer signals and contribution profit.

The goal is to find the likely problem before you start making changes.

Daily, Weekly, and Monthly Review Cadence

You do not need to check every Amazon seller metric at the same time.

SalesDuo recommends using three levels: daily alerts, weekly operating reviews, and monthly trend reviews.

This is a SalesDuo operating framework, not an Amazon rule.

An alert is something that may require quick action, such as an Account Health issue, a stockout, or a major offer problem.

A trend is a pattern you understand better over several days or weeks, such as conversion, TACoS, returns, or profitability.

Daily reviews should focus on alerts. Weekly and monthly reviews should focus more on trends.

Daily: Watch Immediate Risks

Daily monitoring should focus on problems that need quick action.

Review or set alerts for:

  • Account Health issues,
  • important stockouts,
  • unavailable offers,
  • seller-fulfilled shipping problems,
  • major advertising changes,
  • sudden Featured Offer loss.

You do not need a long meeting every day.

The goal is simply to catch serious problems early.

Weekly: Run the Operating Review

A weekly review should connect different parts of the Amazon business.

Review:

  • sales,
  • units,
  • sessions,
  • conversion,
  • Featured Offer %,
  • ad spend,
  • ACoS,
  • ROAS,
  • TACoS,
  • inventory,
  • returns,
  • Account Health changes.

For every major change, ask:

  1. What happened?
  2. What do the other related metrics show?
  3. What should we check next?
  4. Who owns the action?
  5. When will we review it again?

Monthly: Review Trends and Economics

Monthly reviews should focus on bigger business questions.

Look at:

  • revenue trends,
  • contribution profit,
  • portfolio performance,
  • customer acquisition,
  • dependence on advertising,
  • inventory economics,
  • return trends,
  • category performance,
  • strategic priorities.
Cadence Main Purpose Examples
Daily Risks and urgent problems Account Health, stockouts, fulfillment
Weekly Operating performance Sales, traffic, conversion, ads, offer, inventory
Monthly Trends and economics Profitability, portfolio, acquisition, inventory economics

This keeps your team focused on the right metrics at the right time.

Common Amazon Seller Metrics Mistakes

Tracking more numbers does not always lead to better decisions.

The biggest problems happen when sellers look at metrics without enough context.

Mistake Why It Causes Problems Better Approach
Treating every metric equally Important policy risks can be missed Put account risk first
Mixing FBA and FBM metrics Wrong fulfillment targets may be used Clearly label FBA/FBM applicability
Confusing ad sales with total sales Paid performance may look bigger than the full business Compare ad sales with total sales
Looking only at averages Product-level problems can stay hidden Review both account and ASIN-level data

The best dashboard is not the one with the most KPIs.

It is the one that clearly tells your team what to do next.

Turn Amazon Seller Metrics Into an Operating System

Amazon sellers usually don't lack data. The bigger problem is that the data is spread across too many reports and tools.

Account Health, Business Reports, Amazon Ads, inventory tools, Payments reports, and spreadsheets all show different parts of the business.

A better approach is to connect those signals into one simple process:

Protect account health โ†’ spot the change โ†’ find the cause โ†’ assign the action โ†’ review the result.

Start with policy and account-risk metrics. Then look at traffic, conversion, Featured Offer, advertising, inventory, customer signals, and profit before making changes.

If your team spends too much time manually compiling reports, the SalesDuo Business Intelligence Dashboard can bring those signals into a single view.

For brands that want ongoing support rather than managing every Amazon task in-house, explore full-service Amazon account management.

Frequently Asked Questions About Amazon Seller Metrics

1. What are the most important Amazon seller metrics to track?

The most important Amazon seller metrics cover account health, sales and traffic, advertising, inventory, and customer or offer performance.

Start with policy-related metrics such as Account Health Rating and Order Defect Rate. Then track sales, sessions, conversion, Featured Offer percentage, ad efficiency, inventory, and returns.

2. What Amazon seller performance metrics can affect account health?

Order Defect Rate is one of the main account-health metrics.

Seller-fulfilled sellers should also monitor Late Shipment Rate, Cancellation Rate, Valid Tracking Rate, and On-Time Delivery Rate where applicable.

Amazonโ€™s public US guidance reviewed in August 2026 says ODR should generally stay below 1%, seller-fulfilled LSR below 4%, and seller-fulfilled cancellation rate below 2.5%. Check the latest Account Health requirements before publication or major account decisions.

3. What is the difference between FBA and FBM seller metrics?

FBA and FBM sellers both need to track sales, traffic, conversion, offers, and advertising.

However, shipping metrics such as Late Shipment Rate, Cancellation Rate, VTR, and OTDR mainly apply to seller-fulfilled orders. FBA also has inventory-related metrics such as IPI.

4. Where can I find seller metrics in Amazon Seller Central?

Account-health metrics are available in Account Health.

Sales, units, sessions, conversion-related data, and Featured Offer information are available in Business Reports. Advertising metrics are in Amazon Ads Campaign Manager and reports.

Inventory metrics are available in Seller Centralโ€™s inventory and FBA tools, while Payments reports can help you review fees, refunds, reimbursements, and settlement activity.

5. What is a good Order Defect Rate on Amazon?

Amazonโ€™s public US guidance, reviewed in August 2026, says sellers should generally keep the Order Defect Rate below 1%.

Because this is a policy-related metric, check the current Amazon.com requirement in Seller Central before publication or making an important account decision.

6. What is a good IPI score?

There is no permanent universal โ€œgood IPI score.โ€

IPI is an FBA inventory-efficiency metric, but Amazon can change its program and capacity requirements. Use the current information shown in Seller Central when a specific threshold matters.

7. What is the difference between ACoS, ROAS, and TACoS?

ACoS compares ad spend with ad-attributed sales.

ROAS shows how much ad-attributed revenue you earn for each dollar spent on ads.

TACoS compares ad spend with total Amazon sales.

ACoS and ROAS focus on advertising performance, while TACoS provides a broader view of how advertising fits into the broader Amazon business.

8. How often should Amazon seller metrics be reviewed?

SalesDuo recommends daily alerts for Account Health, inventory, and major operational risks.

Use a weekly review for sales, traffic, conversion, advertising, offers, and inventory. Use a monthly review for trends, profitability, and overall business performance.

This is a SalesDuo operating framework, not an Amazon requirement.

9. How do I build an Amazon seller performance dashboard?

Start with the metric, data source, target type, FBA/FBM applicability, owner, and review schedule.

Then add the current value, previous value, trend, alert rule, diagnosis, next action, action owner, and due date.

A scorecard like this can also work as a simple seller performance tracker.

10. Are product reviews and seller feedback different?

Yes.

Product reviews are about the customerโ€™s experience with the product. Seller feedback is about the customerโ€™s experience with the seller and the order.

Keep them separate when reviewing performance, and follow Amazonโ€™s current communication and review policies.
