Track main and subcategory BSR for every ASIN across 21 marketplaces. Daily history and trend averages Seller Central doesn't offer.
A single rank snapshot tells you nothing. Without daily tracking, you can't tell if you're gaining ground or losing it.
Opening Seller Central product pages one by one catches a snapshot, not a trend. By the time you notice a rank drop, it's been sliding for weeks.
If the whole category grew 30% and you grew 15%, your BSR got worse. Without rank context alongside sales, you can't tell momentum from a rising tide.
Your main category BSR can hold steady at #2,000 while your subcategory position drops from #8 to #25. The subcategory is where your actual competitors live. Ignoring it means missing the competitive signals closest to your product.
Is #1,500 in Kitchen & Dining good? Without 30-day and 90-day averages, every BSR number floats in a vacuum.
From daily snapshots to 90-day averages. Nova connects your BSR data with sales and profitability so rank numbers actually mean something.

From setup to BSR visibility in under 5 minutes.
Link through Amazon's official SP-API. Nova automatically identifies every ASIN in your catalog and starts pulling BSR data for main and subcategories.
Every morning, Nova captures a BSR snapshot for every product. Over time, this builds into 7-day, 30-day, and 90-day trend averages you can use for analysis.
See which products are gaining or losing rank. Compare BSR trends across periods, filter by marketplace, and connect rank changes to your sales and profitability data.
Stop bouncing between tools. Read rank, demand and margin in the same row, then open any SKU to compare rank across every marketplace it ships in. See the full setup on the BSR tracker page.

They talk about Nova
If your category position drives your business, your BSR data should be more than a number you glance at.
You're launching new products, running promotions, and adjusting pricing. BSR trends tell you whether those moves are working relative to the category, not just in absolute sales numbers.
You manage dozens or hundreds of ASINs across multiple brands. You need to know which products are gaining rank and which are slipping, without checking each one manually.
Your clients want to know where their products stand. BSR trend reports with 30-day and 90-day averages give you a clear story about category position that goes beyond raw sales numbers.

Amazon Best Sellers Rank (BSR) is a numerical ranking assigned to every product on Amazon based on its sales velocity relative to other products in the same category. A product ranked #1 in its category has the highest recent sales volume. BSR updates hourly on Amazon, reflecting both recent orders and historical sales patterns.
Every product has at least two BSR values: a main category rank (e.g., #3,400 in Health & Household) and one or more subcategory ranks (e.g., #12 in Vitamin D Supplements). The subcategory rank is often more useful because it compares your product against a tighter competitive set. A product can be #5,000 in its main category but #3 in its subcategory.
BSR tracking means capturing these rank positions daily and building trend data over time. Without historical data, a BSR number has no context. Is #2,000 good for your product? You can only answer that if you know it was #3,500 last month and #1,800 last week. Nova automates this by pulling BSR for every ASIN across 21 marketplaces, building 7-day, 30-day, and 90-day averages so you always have the full picture.
Verified 5-star reviews on Trustpilot and Reddit.
“Nova has become a core part of how we run our Amazon agency. Data Share puts clean, structured Amazon data straight into our own stack, so we no longer maintain those pipelines ourselves. The hourly updates mean we spot changes during the day instead of managing accounts on yesterday's data.”
“The P&L view is the big one. It captures everything Amazon-related with the granularity to track down every unexpected expense, giving me a real profit statement I can run the business off of. No more guessing margins or waiting for end-of-month reconciliation.”
“Nova is exactly the kind of tool the e-commerce industry has needed for a while. Fast-moving, responsive, and adding value to every Amazon business at every turn. The team is always open to hearing feedback and new ideas.”
“We had a great experience working with the Nova team. They were incredibly responsive, helpful and professional, and truly committed to improving the tool in ways that made it both simple and genuinely useful. It felt like they were invested in our success.”
“The Nova team has built something truly special. The days of clunky Looker Studio dashboards are over. They are communicative and collaborative, and work hard to make the platform as helpful as possible for their users.”
“Nova keeps us up to date across all of our client accounts and provides a unique set of analytics. The data is live, which lets us make quick decisions faster than with other tools. The events feature is excellent for logging listing changes and running lift tests.”
“I manage multiple brands and Cockpit, P&L and Day-to-Day are now part of my daily workflow. What used to take hours across multiple tools I now see in one place. Antoine and Maxime are clearly building this with real seller challenges in mind, and they listen.”
“The team is genuinely responsive; they actually listen to concerns and implement suggestions into the tool, which is a big part of what makes it so powerful. The UI is clean and managing multiple accounts across marketplaces finally feels organized.”
“We use Nova to manage and analyze our Amazon marketplace data across multiple accounts and regions. Clean interface, useful business insights, and strong visibility into KPIs. Support is proactive and continuous improvements keep landing. Highly recommended.”
