The two-month summary
- Buy Box Checker went international. amazon.co.uk, amazon.ca, and amazon.ie are live, with city and postcode tracking, local currencies, and per-country maps.
- Alerts got sharper eyes. Hijacker Detected, badge gained/lost, and configurable sales rank drop alerts joined Buy Box loss and suppression.
- Your listing content is watched now too. Title, image, bullet, brand, category, and variation changes land on a timeline and in your alerts.
- One daily email, your whole account. The daily digest summarizes every change by email or webhook, and team seats let you share the dashboard without sharing a password.
We ship constantly, but we don't always stop to tell you what landed. This post fixes that. Everything below went live between June 1 and July 30, 2026, and everything is available today.

The Badger went international
The headline of the summer: Buy Box Checker now tracks amazon.co.uk, amazon.ca, and amazon.ie, alongside amazon.com. Every English-language Amazon marketplace, one dashboard. Delivery dates parse the British way, prices show in pounds, euros, and Canadian dollars, and each country gets its own map instead of a map of the States. Shipped July 28 and 29.
Under the hood, brands became country containers: each brand belongs to one marketplace, and brand groups let you line up a brand's US, UK, Canadian, and Irish versions side by side. Their histories and alerts stay separate, because Amazon runs each country as its own catalog with its own Buy Box. The full story, including the grey importer we caught on day one, is in the international launch announcement.

Three new alert types
In July, three new alert types joined Buy Box loss and suppression. All of them run on every check, and all of them reach you in the app, by email, and by webhook. See the full lineup on the Buy Box alerts feature page.
- Hijacker Detected. Tell us which storefronts are allowed to sell your products. The moment a seller you don't recognize takes the Buy Box, you get a distinct hijacker alert instead of a generic loss.
- Badge alerts. When a listing gains or loses its Amazon's Choice or #1 Best Seller badge, you hear about it. Badges move traffic, and they change more often than most sellers think.
- Sales rank drop, on your terms. Alert when BSR jumps by a percentage, by an absolute amount, or past a rank level you set, account-wide or per ASIN. Your slow movers and your bestsellers don't need the same threshold.
We also made the existing alerts more honest. Late July, we rebuilt status classification to rest on seller identity rather than on whether Amazon happened to return delivery data, which eliminated a class of false "you lost the Buy Box" alerts. A quieter inbox you can trust beats a loud one you can't.
Product Page Changes: your listing content, on a timeline
The Buy Box isn't the only thing that changes on a product page. Titles get edited, images get swapped, bullets get rewritten, variations appear and disappear, and sometimes nobody on your team did it. As of July 18, Buy Box Checker snapshots your listing content on every check and records what changed: title, bullet points, description, main image, gallery images added or removed, brand name, category, variations, and video.
Changes land on a dedicated timeline in your dashboard, flow into alerts, and show up in your daily digest. Unexpected content edits are one of the earliest signs of a listing hijack, so this pairs naturally with the Hijacker Detected alert.
Sales rank tracking, charted properly
Every check now captures Best Sellers Rank, and the ASIN page charts it over time. Sounds simple, but BSR is a spiky, log-scale number that changes meaning when Amazon moves a product between categories, so the chart uses an inverted log axis and marks category flips instead of pretending the line is comparable across them. The ASIN table gets a sortable BSR column with a 7-day delta, and CSV exports include rank columns. Shipped July 18 and 19.
Track cities, not ZIP codes
Picking locations used to mean typing ZIP codes. Now you pick cities. Choose Austin, Denver, or any US city from the autocomplete, and we assign it a stable ZIP behind the scenes so results stay consistent check to check. Location labels across the dashboard, the map, alerts, and the digest read like places, not postal codes, and exact-ZIP entry is still there for sellers who want a specific warehouse or suburb. Shipped July 17, and it's the foundation the international city picker builds on.
Why locations matter this much: in our own tracking data, 72.6% of multi-location ASINs show a split Buy Box, with different winners in different locations at the same moment. One national number hides all of that.
One daily email instead of forty
The daily digest shipped June 11. Once a day, at a time that follows your timezone, you get a single email summarizing what changed across your account: Buy Box wins and losses, new alerts, and now content changes and rank moves too. Prefer it in Slack or another chat tool? The same digest delivers to any webhook URL, shaped so chat platforms render it cleanly. One-click unsubscribe, no login required.
Team seats, scoped to the right brands
Stop sharing passwords. Team seats shipped in early July: invite teammates for $5 per seat per month, up to 10 seats. Later in the month we added per-brand access, so an agency can give a client's team member exactly one brand, and a brand owner can keep a contractor out of everything else. Members see what they're granted, nothing more.
A free Buy Box check, no account required
Want to see what we see before signing up? Paste any ASIN or Amazon URL into the free Buy Box checker and get a real, live check across multiple cities in the US, UK, Canada, or Ireland. No account, no seller login. Every result gets a shareable link, which turns out to be a handy way to show a client or a skeptical colleague who actually owns the Buy Box in Denver.
Under the hood
Less visible, still worth your time: the homepage now loads in a fraction of the time it used to, because third-party marketing scripts wait until the page is interactive. We published a proper privacy policy. And the codebase picked up continuous integration, hundreds of new tests, and a hardening pass across the billing and database layers, which is the unglamorous work that keeps the glamorous features honest.
That's two months. The queue for the rest of the summer includes more marketplaces and deeper competitor tracking. If there's a feature or a country you need, reply to any of our emails, because that genuinely moves it up the list.
Frequently asked questions
Do the new features cost extra?
No. Everything in this changelog ships to every plan at no added cost, with two footnotes: international marketplaces require a paid plan, and team seats are an optional add-on at $5 per seat per month, up to 10 seats. A check is still a check, in any country.
Which Amazon marketplaces does Buy Box Checker support now?
Four: amazon.com, amazon.co.uk, amazon.ca, and amazon.ie. That covers every English-language Amazon marketplace. Each brand you create belongs to one country, and brand groups let you line up the same brand's countries side by side on your dashboard. More marketplaces are coming one at a time.
What can Buy Box Checker alert me about now?
Buy Box losses and suppression, an unrecognized seller taking your Buy Box (Hijacker Detected), Amazon's Choice and #1 Best Seller badges gained or lost, sales rank drops with thresholds you control, and product page content changes like edited titles, images, or bullets. Alerts arrive in the app, by email, and by webhook.
Can I try it without creating an account?
Yes. The free instant checker on the homepage and at /buy-box-checker runs a real Buy Box check on any ASIN in the US, UK, Canada, or Ireland, no signup and no seller account required. Every result gets a shareable link you can send to a colleague or client.
