Track Best Seller Rank (BSR) over time for every ASIN on your project across all the categories they're listed in, so you can spot when sales are slowing and figure out whether it's just you or the whole niche.
Plan availability: The BSR tracker is included on all four new plans: Starter, Professional, Team, and Agency. Compare plans and limits.
When to use this
BSR is one of the earliest signals that something has changed in your sales pattern. Open the BSR tracker when you want to:
Diagnose a sales drop. If your BSR is getting worse but your competitors' BSRs are stable, the issue is something about your listing or your traffic. If everyone's BSR is sliding at the same time, the niche itself is cooling off.
See your true competitive position, not just your sales trend. Rising sales alongside a falling BSR mean seasonality is lifting you while competitors are pulling ahead even faster. That's a warning sign your raw sales numbers won't show you.
Confirm a sales lift came from a real change you made, not just a rising tide across the category.
Spot competitors climbing fast in the same category before they become a threat.
Get a quick read on niche health over the last 30 days.
Datarova captures BSR daily for every ASIN on the project, in every main category and subcategory it appears in, so the data is already there waiting for you.
Open the BSR tracker
Open your project and go to the Ranks tab.
Click BSR.
The grid shows every ASIN on the project as a row, with BSR across the columns over time.
An Amazon Seller Central account has to be linked to Datarova to use the BSR Tracker. This is required as the Seller Central APIs are used to retrieve the BSR data for the ASINs you track each day.
Choose a category
Use the category dropdown at the top-left to pick which category you want to see BSRs for.
The dropdown groups categories by main category, with relevant subcategories nested underneath. The number next to each category shows how many of your project's ASINs sit in that category.
If your project has ASINs spread across more than one main category (for example, some in Kitchen & Dining and some in Home & Kitchen), you'll see all of them grouped together here. Switch between them to compare BSR within each category context.
Read the grid
Each row is an ASIN. Each column is a date. The number in the cell is that ASIN's BSR in the selected category on that day. Lower is better.
A few things worth knowing:
Cell colours are dynamic per category. A BSR in the top 1,000 is excellent in a broad main category like Kitchen & Dining but unremarkable in a tight subcategory like Garlic Presses, where you'd want to be in the top 10. The colours adjust automatically based on the category you've selected, so green always means "doing well in this category context."
You can sort by any column. Click a column header to sort by that day's BSR, which is useful for ranking your competitors at a particular point in time.
You can add context columns with Edit Columns in the top-right (brand, price, rating, review count, visibility, and more). Worth adding two or three columns when you're investigating a sales drop, so you can see whether a competitor's price or review changes line up with their BSR movement.
Tips
Check both main category and subcategory views when investigating a change. They tell you different things: subcategory tracks how you're doing against direct competitors, main category tracks your broader visibility.
Compare your BSR trend to your top three or four direct competitors first, not the whole list. If those few are moving with you, the niche is shifting. If they aren't, something specific to your listing is.
BSR is a noisy daily metric. Look at the trend across a week or longer rather than reacting to a single day's number.
