How to Improve Your Amazon Seller Rating in 2026

Most sellers chase the wrong number. They obsess over their five-star feedback percentage, then get blindsided when their Account Health Rating drops below 200 and listings stop winning the Buy Box. The public seller rating on your storefront is one thing. The score Amazon actually uses to decide whether you keep selling is another. Stop optimizing for what customers see. Start optimizing for what Amazon measures.

## The Two Ratings That Actually Matter

There are two separate systems you need to manage. Treating them as one number is the first mistake.

1. Seller Feedback Rating - the public-facing percentage. Shown on your storefront, calculated as (positive feedback ÷ total feedback) × 100. 4- and 5-star ratings are positive, 3-star is neutral, 1- and 2-star is negative. Customers see your 12-month rating once you have 10+ feedbacks in that window; otherwise they see lifetime. For competitive Buy Box positioning, aim for 95%+ positive. Below 90% starts to hurt.

2. Account Health Rating (AHR) - Amazon’s 0-to-1,000 internal score. This determines whether your account stays active. New sellers start at 200. You earn 4 points for every 200 successfully fulfilled orders over a 180-day window. Policy violations deduct 2-8 points each. Critical violations drop you to zero instantly.

AHR Zone	Score	Status	What It Means
Healthy	200-1,000	Green	Full privileges, no deactivation risk
At Risk	100-199	Yellow	Warning - deactivation possible if you don’t correct it
Critical	0-99	Red	Eligible for immediate deactivation

AHR lives in your Seller Central Account Health Dashboard. The feedback percentage on your storefront influences customer perception and Buy Box eligibility. The AHR decides whether you have an account at all. The two connect through one metric: negative feedback (1-2 stars) feeds your Order Defect Rate, and an ODR above 1% triggers the policy violations that deduct AHR points. Manage the input metrics and both ratings take care of themselves.

## Amazon’s Core Performance Metrics and Thresholds

Your ratings are a downstream output. These are the metrics that drive them. Memorize these numbers - they are the actual scorecard.

Metric	Amazon Minimum	Recommended Buffer	Measurement Window
Order Defect Rate (ODR)	< 1%	< 0.5%	Rolling 60 days
Late Shipment Rate (LSR)	< 4%	< 2%	Rolling 10 & 30 days
Pre-Fulfillment Cancel Rate	< 2.5%	< 1%	Rolling 7 days
Valid Tracking Rate (VTR)	> 95%	> 99%	Rolling 30 days
On-Time Delivery Rate (OTDR)	> 90%	> 95%	Rolling 30 days
Invoice Defect Rate (IDR)	< 5%	< 2%	Amazon Business orders
Customer Response Time	< 24 hours	< 12 hours	Continuous

Amazon’s minimums are the floor, not a target. Run at the minimum and a bad week tips you over. The buffer column is where competent sellers actually operate. The windows also matter: Cancel Rate uses a 7-day window and can flip on a single rough week. ODR drags a 60-day tail, which is why recovery from a bad quarter is slow.

A quick number: at 500 orders per month over 60 days, you have a 1,000-order denominator. Five defective orders = 0.5% ODR. Ten = 1%. The math is unforgiving at low volume, which is why small sellers are disproportionately exposed to sudden suspensions.

As of early 2026, Amazon tightened enforcement. Metrics within 20% of a threshold (ODR above 0.8%) now trigger early warnings, and Q1 2025 industry data indicated roughly 14% of seller accounts faced some form of suspension.

## What to Fix First If Your Score Is Slipping

The instinct is to work on whichever metric you just got an email about. That’s backwards. Fix in this order:

1. Anything hitting a short-window threshold first. LSR above 4% on a 10-day window is more urgent than ODR trending toward 1% on a 60-day window - you have less time to recover. Same logic for Cancel Rate’s 7-day window.
2. ODR second, because its recovery is slow. Defective orders stay in the rolling window for 60 days. You cannot hurry recovery; you can only stop adding to it and dilute with clean orders.
3. Feedback percentage last. Public rating responds to volume. Fix it by generating positive feedback faster than negatives accumulate, not by appealing individual 1-stars (slow and often futile).

Exception: if you’re sitting on a granted A-to-Z claim you genuinely believe was unwarranted, appeal it immediately. A reversed claim reverses the ODR impact within about seven days.

## Order Defect Rate: The Metric Sellers Underestimate

Order Defect Rate is the one that suspends accounts. It has three components:

• Negative feedback (1-2 stars)
• A-to-Z Guarantee claims - but only seller-funded granted claims. Denied, withdrawn, and Amazon-funded claims don’t count.
• Credit card chargebacks initiated by the buyer’s bank

Formula: (Orders with defects ÷ Total orders) × 100, over a rolling 60-day window with a 14-day reporting lag. Each order can only contribute one defect - so if the same order gets a 1-star review and an A-to-Z claim, it counts as one, not two.

How to actually drive ODR down:

• Respond to every buyer message within 24 hours. Most A-to-Z claims start as a buyer message that went unanswered for three days.
• For FBM orders, buy labels through Amazon Buy Shipping. Shipments purchased through Buy Shipping with a confirmed on-time scan are protected against “item not received” claims - Amazon covers the refund and it does not count toward your ODR.
• Use FBA where the economics work. FBA-fulfilled orders where the issue is delivery-related (lost, late, damaged) are Amazon-funded and do not hit ODR. FBA does not protect you against wrong-item or SNAD (significantly not as described) claims - those are still yours.

If you stop generating defects, expect 60-74 days for full recovery as orders age out.

## Late Shipments, Cancels, and Tracking

If you’re FBM, these three are where most accounts get in trouble. They also have the most mechanical fixes.

Late Shipment Rate. LSR is calculated against the expected ship date implied by your handling time. If your handling time is 2 days and you confirm on day 3, that’s late. The fix isn’t “ship faster” - it’s setting an honest handling time. Sellers routinely promise 1-day handling to look attractive, ship on day 2, and wonder why LSR is at 5%. Set handling to what you can hit on a bad day, not an average one.

Pre-Fulfillment Cancel Rate. Seller-initiated cancels on a 7-day window. Buyer-requested cancels don’t count. The usual culprit is inventory desync - oversold SKUs you then have to cancel. Centralized managing orders and a safety buffer (hold back ~5% of stock from listed quantity) prevent most of these.

Valid Tracking Rate. As of January 2025, VTR applies to all carriers, not just Amazon-integrated ones. Missing tracking numbers, wrong carrier codes, or tracking that doesn’t update are all VTR hits. Integrate your shipping software so labels and tracking flow automatically.

On-Time Delivery Rate. Required above 90% since late 2024. Promise extensions don’t count. Honest delivery estimates based on your actual zone performance beat optimistic ones that get missed. See Shipping and Order Timeline for more.

## Handling Negative Feedback and A-to-Z Claims

You cannot delete feedback. You can petition Amazon to remove it under specific conditions - and those conditions matter, because successful removal pulls that feedback out of your ODR calculation.

Amazon will remove feedback that:

• Reviews the product, not your service (“the fabric wore out” is a product review)
• Contains offensive language, abuse, or personal information
• Concerns only pricing
• Concerns only FBA delivery issues (usually struck through rather than removed, but either way it stops counting toward ODR)

Request removal through Seller Central > Performance > Feedback Manager. You have 90 days from the feedback date; after that, the system blocks the request. Audit new negative feedback weekly.

One recent change to flag. On August 4, 2025, Amazon introduced star-only ratings - customers can submit a star rating without written feedback. The catch: star-only ratings cannot be appealed through Feedback Manager. You have to use the “Report a violation” process for abusive ones. Net effect: more feedback volume overall (helps your percentage), but less ability to challenge individual negatives. See removing negative feedback for deeper tactics.

For A-to-Z claims: respond to the initial message within 48 hours. Amazon weights seller responsiveness heavily when deciding claims. An unanswered claim is almost always granted in the buyer’s favor. A well-documented response - shipping proof, tracking, photos of the packed item - frequently results in a denied claim that doesn’t count against you.

## Account Health Assurance: The Reward for Staying Healthy

This is what you’re playing for. Account Health Assurance (AHA) prevents immediate deactivation when an issue arises - Amazon contacts you first, typically via your emergency contact phone, and gives you about 72 hours to respond before enforcement.

To qualify, you need all of the following:

• Seller account for at least 1 year
• Professional selling plan
• AHR of 250+ for at least 6 consecutive months (no more than 10 days below 250)
• A valid emergency contact number in Seller Central

Amazon invites qualifying sellers automatically; there’s nothing to apply for. Once enrolled, an AHA badge appears on your Account Health page.

Caveats: AHA does not protect against all deactivation types. Critical violations (counterfeit, safety, restricted products) still trigger immediate enforcement. And here’s the irony - if your AHR drops below 250 because of whatever triggered the incident, you can lose AHA protection exactly when you’d want it most. Treat AHA as a reward for consistent performance, not a safety net for poor performance.

In 2025, Amazon expanded Account Health Specialists - dedicated support staff - to professional sellers worldwide. Anyone on a Professional plan can reach out, AHA-enrolled or not. Use them early. Most account-health problems are cheaper to fix as questions than as appeals.

## Frequently Asked Questions

What is a good Amazon seller rating?

For the public-facing feedback percentage, aim for 95%+. Below 90% starts to affect Buy Box win rate. For the Account Health Rating, 200-1,000 is “Healthy” - but 250+ for six months unlocks Account Health Assurance, which is the practical target.

How is Amazon’s Account Health Rating calculated?

AHR is a 0-to-1,000 score. New sellers start at 200. You earn 4 points for every 200 successfully fulfilled orders over a rolling 180-day window. Policy violations deduct 2-8 points each, and critical violations (counterfeit goods, severe safety issues) drop your score to zero immediately.

How long does it take to recover from a high Order Defect Rate?

ODR uses a rolling 60-day window with a 14-day reporting lag. If you stop generating new defects, expect about 60-74 days for a full recovery as older defective orders age out.

Can I remove negative feedback on Amazon?

Not directly, but you can request removal within 90 days. Amazon will remove feedback that’s actually a product review, contains abusive language or personal information, concerns only pricing, or concerns FBA delivery issues. Star-only ratings left since August 2025 cannot be appealed through Feedback Manager.

Does FBA protect my Account Health Rating?

Partially. FBA shields you from ODR hits on delivery-related A-to-Z claims (lost, late, damaged). It does not protect against wrong-item, counterfeit, or SNAD claims - product accuracy is still your responsibility.
