Features
See your Buy Box the way Amazon actually works
Amazon assigns Buy Box winners by location. One ZIP code can show you winning while another shows a competitor. We give you the full picture.
ZIP Code-Level Tracking
Amazon shows different Buy Box winners in different locations. A single national check misses the 30% of products with location-level issues. We check every ZIP code you care about.
No Amazon Account Needed
There is no Seller Central login or API connection to set up. Paste in ASINs and go. Because we check public product pages, you can monitor any ASIN, your own catalog or a competitor's.
Continuous Monitoring
Your Buy Box status can change at any time. We check automatically throughout the day so you see problems within minutes, not days.
Instant Alerts
Get notified the moment your Buy Box status changes in any location. Catch hijackers, suppressions, and lost Buy Boxes before they eat into your sales.
Listing Hijacker Alerts
When an unauthorized seller takes your Buy Box, we flag it as a hijacker, not just a generic loss, and show who it was and how far they undercut you. Keep an allowlist of your real distributors so approved resellers never trip a false alarm, and authorize a new one in a click.
Product Page Change Tracking
Amazon and bad actors can quietly rewrite your listing: titles, bullet points, images, even your brand name. We snapshot every product page daily and show you exactly what changed, old versus new.
Wake Up Already Knowing
A daily digest hits your inbox with an AI briefing of what changed: what you won, what you lost, and who took it. You start the day ahead of problems instead of finding out days too late.
Alerts Where Your Team Works
Pipe the same digest to any webhook and Buy Box changes show up in Slack, Teams, Zapier, or n8n. Route them onward to SMS or WhatsApp so the whole team reacts, not just one inbox.
Ownership Analytics
See your 30-day Buy Box ownership percentage broken down by ASIN and location. Spot patterns and find the products that need your attention first.
Best Sellers Rank Trends
We record your Best Sellers Rank on every check and chart it over time. Spot momentum, catch sudden drops, and see 7-day movement across your whole catalog at a glance. When Amazon recategorizes your product, the chart says so instead of showing a fake cliff.
Sales Rank Drop Alerts
Set the drop that matters for each product and hear about it the moment its Best Sellers Rank slides, whether that is a percentage slip or falling out of your top spots. The Badger catches the slide before it shows up in your numbers.
Badge Change Alerts
Amazon's Choice and the #1 Best Seller badge move real sales. Know the instant you win one or lose one, so you can defend the badges that are driving your orders.
Multi-Brand Dashboard
Manage ASINs across multiple brands and seller accounts in one place. Bulk-add ASINs and get a single view of your entire catalog.
Delivery Date Tracking
See Prime and free delivery dates alongside Buy Box data for every location. Understand where slow delivery is costing you the Buy Box.

How ASIN checks work
One ASIN monitored in one location counts as a single ASIN check, so your usage is ASINs × locations. Tracking 100 ASINs across 10 cities uses 1,000 checks. Tracking those same 100 ASINs in a single location uses 100. Unlimited locations removes the cap on how many ZIP codes you can choose. It does not add checks on top of your plan.

Questions about ASIN checks and plans
How usage is counted, what locations cost, and how to size your plan.
What is an ASIN check?
An ASIN check is one product (ASIN) monitored in one location. Your plan limit is the total number of these checks, and because each location is counted separately, your usage is ASINs × locations. For example, tracking 100 ASINs across 10 cities uses 1,000 ASIN checks. Tracking those same 100 ASINs in a single location uses 100.
Why do locations multiply my ASIN checks?
The Buy Box can be won by different sellers in different cities, so we check each ASIN independently in every location you choose. That separate, per-location check is what makes regional Buy Box tracking possible, and it is the unit your plan counts. One ASIN watched in five ZIP codes is five checks.
What does "unlimited locations" mean?
On the Patrol and Badger Pro plans, unlimited locations means there is no cap on how many distinct ZIP codes you can monitor across your account. It does not add extra ASIN checks on top of your plan. You still spend one ASIN check per ASIN, per location, so your total ASINs × locations needs to fit inside your plan's check allowance.
How do I estimate how many ASIN checks I need?
Multiply the number of ASINs you want to watch by the number of locations you want to watch them in. Tracking 250 ASINs in 4 cities is 1,000 checks. If you only need national coverage with one location per ASIN, your ASIN count and your check count are the same number.
How often are Buy Box checks run?
Every plan refreshes your Buy Box status once daily across all of the locations you monitor.
What happens when I reach my plan limit?
You can keep monitoring everything you have already added. To track more ASINs or add more locations beyond your limit, upgrade your plan for more ASIN checks, or earn bonus checks through the referral program.
What counts as a product page change?
We track your title, bullet points, description, main image, gallery images, brand name, category, variations, and video status. Every change is logged with a before and after view, and shows up in your alerts and daily digest the same day.
Where does the Best Sellers Rank data come from?
We capture BSR from the public product page on every daily check, both the main category rank and the subcategory rank. No Seller Central connection needed. The trend chart builds automatically from day one.
