See what your BSR is really telling you
Track main and subcategory BSR for every ASIN across 21 marketplaces. Daily history and trend averages Seller Central doesn't offer.
A rank without history is just a number
A single rank snapshot tells you nothing. Without daily tracking, you can't tell if you're gaining ground or losing it.
You check BSR manually and miss the patterns
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.
A sales spike doesn't mean you're winning
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.
Subcategory ranks tell a different story
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.
No historical view means no context
Is #1,500 in Kitchen & Dining good? Without 30-day and 90-day averages, every BSR number floats in a vacuum.
Rank data that builds over time
From daily snapshots to 90-day averages. Nova connects your BSR data with sales and profitability so rank numbers actually mean something.

What is Amazon Best Sellers Rank?
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.
Why Sellers Choose Nova for BSR Tracking
"We used to check BSR manually for our top 20 products. We had no idea our #4 subcategory product had dropped to #19 over three weeks. By the time we noticed, a competitor had taken our spot with an aggressive PPC push. Daily BSR tracking would have caught that in week one."
