Your Amazon Buy Box percentage is the share of page views where your offer occupied the Buy Box, meaning the Add to Cart button belonged to you. Amazon now calls it the Featured Offer. It matters more than almost any other single number, because the overwhelming majority of Amazon orders go through that button rather than through the other-sellers list.
Amazon now publishes what decides it: total price including shipping, the delivery promise, free shipping, free returns, and seller performance. It also says what doesn’t count: reviews, Prime eligibility and whether you use FBA or ship yourself. Price gets all the attention. It isn’t the whole answer, and that’s exactly why cutting price so often fails to win the box back for sellers who assumed it would.
If you’d rather have someone watch the numbers and fix the causes for you, our Amazon account management service covers Featured Offer monitoring alongside account health and pricing.
Where to find your percentage
In Seller Central, open Business Reports and look for the Featured Offer (Buy Box) percentage at the ASIN level. Amazon defines it as the number of page views in which your offer was featured, divided by the total page views for your products, so set the date range wide enough to show a trend across several weeks rather than a single noisy day that tells you almost nothing.
I’d check this weekly on any product with competing offers. It moves before your sales do, so a falling percentage is an early warning. Wait for revenue to drop and you’ve already lost a week.
If your ranking has already moved, Buy Box is the second thing to check after stock. Our guide on diagnosing a ranking drop runs the full sequence in the order worth checking.
Reading the report properly
I think this column is easy to misread. Two mistakes deserve naming.
The first is reading it at account level. That figure averages everything you sell. Uncontested private label products then mask a real problem on the few ASINs where you compete. I’d only ever read this at ASIN level, sorted by revenue, because that is where the money actually is.
The second is reading a single day. Share rotates. When two offers are closely matched Amazon shares the box between them, so a day at 40% and a day at 60% can be the same underlying situation. Look at two weeks and read the trend, not the point.
There’s a third thing the report won’t tell you, and I’d argue it matters most. It shows you lost the box. Not who won. Not why. For that you have to open the listing yourself, ideally logged out and from the shipping address your buyers use, and read every competing offer line by line: their price, their shipping cost, their return terms and the delivery date each one shows.
I’d do that manually on your top three competed products rather than trying to automate it. Five minutes each, once a week. My bet is that the cause will usually be obvious on the live page, and invisible from the report alone.
One more habit I’d recommend. When you find the reason, write it down with the date. Buy Box losses repeat, and a short history tells you whether this is the same competitor returning or a new problem, which changes the response entirely.
What “Buy Box wins” actually means
Sellers talk about “Buy Box wins”. Amazon doesn’t. There’s no report metric by that name, but three things come close:
| Where | What it shows |
|---|---|
| Business Reports | Your Featured Offer (Buy Box) percentage: featured page views divided by total page views |
| Selling Partner API offer data | Whether an offer is currently in the Buy Box; Amazon says there can be up to two winners per ASIN at once, one Prime-eligible and one not |
| Featured Offer Expected Price (API) | The price at or below which Amazon expects your offer could become the Featured Offer, with no guarantee because competing offers change |
Rotation is normal. When offers are closely matched, Amazon says the Featured Offer can rotate between them. Hence a percentage, not a yes or no.
A September 2026 change. Amazon dropped its seller eligibility requirement, so every seller’s offer is now evaluated. Big shift. Being considered isn’t winning, though. Not even close. An uncompetitive offer won’t be picked, and Amazon may feature nobody at all.
The factors Amazon says decide the Featured Offer
| Factor | What Amazon says | What to do about it |
|---|---|---|
| Total price | Item price plus shipping; coupons and promotions help | Compare your landed price against each competing offer, not your item price alone |
| Delivery promise | Faster, more specific delivery is preferred | Check the delivery date buyers see on your offer versus theirs |
| Free shipping | A $40 offer with free shipping is preferred to $35 plus $5 shipping | Build shipping into the price where you can |
| Free returns | Counts in your favor | Offer free returns if your margin allows |
| Seller performance | Order volume (with steps so smaller sellers aren’t disadvantaged), chargeback rate, and customer complaint types | Keep complaints and chargebacks low |
| In stock and shippable | Out-of-stock offers can’t be featured | No stock, no Buy Box. There is no partial credit |
What Amazon says it ignores: customer reviews and ratings, whether the offer is Prime-eligible, and whether it’s FBA or seller-fulfilled. Surprising, right? If everything else is equal, FBA and FBM offers are “equally likely” to be featured. Amazon also says it ranks offers the same way for every product and never uses manual overrides.
Total price is the one people get wrong, and it’s an expensive mistake. Amazon compares price plus shipping, so a seller at $24 with free delivery beats you at $22 plus $4 shipping. When you seem cheapest and still lose, check this first.
Delivery is where FBA still matters, indirectly. Speed wins. FBA isn’t a factor in itself, but FBA offers usually show fast, free delivery, and those are factors. If you ship yourself, match the delivery promise and the free shipping, and Amazon says your offer is as likely to win as an FBA one. Our guide to FBM shipping requirements covers what that takes. For a warehouse you run yourself, my checklist is short: a handling time you can keep daily, a carrier fast enough to match the FBA delivery date, and shipping built into the price. Then hold it.
Why cutting price often fails
This is the mistake I’d most want to prevent. It costs margin and fixes nothing.
Picture losing to an offer with faster or free delivery. Price may not be the binding constraint. You can undercut it and still lose, because the delivery promise is doing the work. You’ve given away margin. Nothing gained.
Same for seller performance. If complaints or chargebacks drag your offer down, a lower price just makes recovery dearer.
So before touching price, answer one question: what changed? If a competitor arrived, price may be relevant. If your delivery promise slipped, your performance dropped, or you were briefly out of stock, price is irrelevant. Fix the actual cause.
In my view, that single question saves more margin than any repricing strategy.
Repricers, and how to use one without harm
A repricer adjusts your price automatically against competing offers, and it’s easy to configure badly. On a catalog with many competed ASINs it’s close to essential. Manual repricing doesn’t scale.
Two rules I’d treat as non-negotiable.
Set a floor and mean it. The floor should be your genuine break-even including every fee, not a number that feels low. Repricers race to the floor. A wrong floor means reliable losses.
Do not chase unauthorized sellers to the bottom. If someone selling counterfeit or gray-market stock is undercutting everyone, matching them is a losing fight. Don’t do it. Report them and hold your price.
Beyond that, prefer a rule that targets the Buy Box rather than the lowest price. Winning at a penny below the next offer is the goal. Being cheapest on the page isn’t. They’re different settings.
How to track your Buy Box (Featured Offer) share
An Amazon Buy Box tracker is anything that tells you, over time, whose offer held the box and at what price. Amazon gives you part of that free. Tools fill the rest.
What Amazon shows you
Three places inside Seller Central, as of November 2026:
- Business Reports. The Featured Offer percentage per ASIN, calculated as featured page views divided by total page views, per Amazon’s Becoming the Featured Offer page. This is your trend line.
- Pricing Health. It lists offers that can’t be featured because of price, offers deactivated as potential pricing errors, and offers priced within 5% of the Featured Offer. This is the closest thing to a status check.
- The live detail page. It shows who holds the box right now, which no report does.
You may remember a “Featured Offer eligibility” status, the green tick beside eligible listings. That’s gone. Amazon’s Featured Offer eligibility page now says it has been removed, because as of September 2026 Amazon no longer has a seller eligibility requirement. Every seller’s offer is evaluated, and FBA and seller-fulfilled offers are treated alike. So a missing tick no longer explains anything. Look at Pricing Health instead.
What third-party trackers add
Amazon’s report tells you that you lost share. It doesn’t tell you who took it, when, or at what price. That gap is the whole job. Three examples, described from each company’s own pages as checked on November 10, 2026 (not endorsements, and not a ranking):
| Tool | What its own site or docs say it tracks |
|---|---|
| Keepa | Buy Box price history, a history of the seller IDs that held the Buy Box, and per-seller stats including an approximate percentage of the time each seller won it |
| Helium 10 Alerts | Alerts for hijacker activity and listing changes, and a check that you have the Buy Box and are the only seller |
| BQool repricer | Repricing rules aimed at winning or matching the Buy Box, plus filters that surface Buy Box losses; plans listed from $25 a month |
My view: for a handful of competed ASINs, Business Reports plus a weekly look at the live page is enough, and paying for software before you’ve read your own reports properly for a month or two is money I’d rather see spent on stock. Once you have dozens of contested listings, a history tool earns its fee, because “who held it last Tuesday” is the question you’ll keep asking.
Lost the Buy Box? Diagnose in this order
When a lost Buy Box on Amazon shows up, work cheapest check first:
- Is the offer buyable? Stock available, not reserved or stranded, and shippable to the shopper’s area. No stock means no Featured Offer.
- Is anyone featured at all? If the page says “See All Buying Options” or the item looks unavailable, follow our currently unavailable decision tree before anything else.
- Pricing Health. Look for your ASIN among offers that can’t be featured or were deactivated for pricing.
- Landed price. Your price plus shipping against each rival’s total.
- Delivery date and terms. The date the buyer sees, free shipping, free returns.
- Account Health and seller performance. Every metric inside target, plus chargebacks and Voice of the Customer complaints.
- A new seller on the page. If it’s an unauthorized one, report it rather than racing them down.
Only after those seven would I touch price. In practice the first six take about twenty minutes. I’d expect them to name the cause most of the time, and price is where most sellers start, which is why so many end up cheaper and still losing.
When nobody has the Buy Box
Sometimes the Add to Cart button is missing entirely and the page shows only “See All Buying Options.” This is worth recognizing because the causes are specific.
Don’t panic. Amazon says it may show no Featured Offer when none of the offers meets its customer-experience requirements, even if yours is the only offer. Price is the first thing I’d suspect: Amazon’s Pricing Health page flags offers that can’t be featured because they sit well above recent or external prices. Sometimes it means the product is restricted, or the listing has a problem.
The fix, when it is pricing, is to bring your price to something Amazon considers reasonable. If you use the Selling Partner API, the Featured Offer Expected Price tells you the level Amazon has in mind. Annoying, but fixable. Honestly, it’s frustrating when your costs justify a higher price, and I’d rather say plainly that there isn’t always a way around it.
The longer game
I’d treat Buy Box share on a competed ASIN as a permanent contest. It never stays solved.
In my view two things compound in your favor. Order volume is part of seller performance, so steady selling helps over time, and Amazon says it takes steps so smaller sellers aren’t disadvantaged. And low complaint and chargeback rates keep your offer competitive during the moments that matter.
The third thing, and the strongest, is not competing at all. A product only you sell has no Buy Box contest, which is one of several reasons private label is worth the additional risk. Our guide to finding low competition products covers how to choose one that stays uncontested for a while.

FAQ
What is Amazon Buy Box percentage?
The share of your product’s page views where your offer was the Featured Offer, meaning the Add to Cart button was yours. Amazon calculates it as featured page views divided by total page views, in Business Reports at ASIN level.
What does Buy Box wins mean?
There’s no Amazon metric called “Buy Box wins”. Sellers use it for how often their offer is featured, which Amazon reports as the Featured Offer percentage. Through the API, Amazon also flags whether an offer is currently the Buy Box winner; there can be one Prime and one non-Prime winner per ASIN.
What determines who wins the Amazon Buy Box?
Amazon lists total price including shipping, the delivery promise, free shipping, free returns and seller performance, and the offer must be in stock. It says reviews, Prime eligibility and FBA versus FBM are not considered.
What is the best Amazon Buy Box tracker?
Start with what’s free: the Featured Offer percentage in Business Reports and the Pricing Health page. Add a third-party tool such as Keepa, Helium 10 Alerts or a repricer like BQool when you need history of who held the box, or alerts when it changes.
Why did I lose the Buy Box on Amazon?
Usually one of four things: no buyable stock, a Pricing Health flag, a rival with a better landed price or delivery date, or slipping seller performance. Even the “lowest” price can lose, because Amazon compares price plus shipping. Check in that order before cutting.
Does FBA help win the Buy Box?
Not directly. Amazon says FBA and seller-fulfilled offers are equally likely to win if everything else is equal. It helps indirectly, since FBA offers usually show fast, free delivery, and both of those count.
Should I use a repricer?
With many competed listings, yes. Put the floor at true break-even after all fees, and aim the rule at the Buy Box, not the lowest price on the page.
Why does no one have the Buy Box on my listing?
Amazon says it may feature no offer when none meets its customer-experience requirements, even with a single offer. A price well above recent or external prices is the first thing to check in Pricing Health; stock and shipping coverage come next.
