BSR Explorer ​

Use the BSR Explorer to follow your products' sales ranks over a selected period. Best Seller Rank (BSR) describes a product's position within a category: a lower number means a better rank.

Owners, Admins, and Viewers can view and export BSR data. Only Owners and Admins can manage BSR KPI sets and add custom events from the chart. See Permissions.

Where BSR data comes from ​

sellerfox updates sales ranks once a day through SP-API.

  • Amazon does not provide historical BSR data through SP-API. The BSR history in sellerfox therefore starts with the first reading after workspace onboarding is complete. sellerfox cannot load earlier ranks.
  • Each marketplace has a separate rank history. For example, an ASIN can rank differently on amazon.de and amazon.fr.

Depending on the category, Amazon assigns a shared Best Seller Rank (BSR) to the product family or separate ranks to individual variations.

Choose a period ​

In “Filters”, choose a preset under “Time frame” or use “Select date range …” to set your own range. The default is “Last 30 days”.

The selected period applies to the overview and the rank history in the detail view.

Read the overview ​

The overview shows one row per product family and marketplace. Use “BSR KPI Set” to choose columns for the main category or subcategories. The default is “Main category”.

Use “KPI selection...” to choose your own columns. See KPI sets for saving and managing a selection.

Rank, change, and trend refer to the selected period.
ColumnWhat it shows
Sales (Total)the product family's revenue in the period, in the workspace's target currency
“… BSR”the last rank in the selected period, with the category name below
“… change”the change in rank over the selected period
“… trend”the rank history in the period as a line

A green arrow means an improvement toward rank 1; a red arrow means a decline. A 0 means the rank is unchanged. A dash means a rank is missing at the start or end of the evaluated period. If Amazon changes the category assignment, the displayed change may be based on ranks from different categories.

For product families, each category shows the product with the best rank. Revenue covers all variations.

“As of:” shows the last day with BSR data in the selected period. Hover over the date to see the date for each marketplace. If the period reaches today and the data for at least one marketplace is more than three days old, a warning icon appears.

A product with no main-category rank on the marketplace's latest data date is missing from the overview. You can still open the product's stored rank history through “View BSR history” on the product detail page.

Revenue and rank are updated separately and may reflect different update times.

Click a column header to sort by revenue, rank, or change.

Filter and open a product ​

Use “Product list” to narrow the overview to a product selection or a saved product list. If the workspace has several active marketplaces, you can also filter by marketplace. Confirm with “Apply filter”. See Products & product lists.

Open the rank history with “View BSR history”. For product families, this opens the product with the displayed main-category rank. Switch between the parent and variations in the product header, or use “Change product” to select another product. Use “go to product detail” to open the product detail page.

Export BSR data ​

Use “Export” to download the data as XLSX or CSV. The column headers in the file are always in English.

  • Overview: the filtered products for the selected period, with columns from the selected BSR KPI set, excluding trend columns.
  • Detail view: the product's daily ranks and categories for the selected period, excluding additional Product KPIs shown in the chart.

Read the rank chart ​

The chart in the detail view shows how ranks developed over the selected period.

The summary above the chart can highlight notable changes in ranks and product metrics. Changes happening at the same time do not establish a cause.

Above the chart, you can see the rank and change for the main category and up to three subcategories. Use the checkboxes to show or hide the lines. The link icon opens the category on Amazon.

The detail view shows the selected product's rank history for the selected period.

The chart places rank 1 at the top. Each point represents a stored reading. Days without a reading have no point. The solid line shows the main-category rank. Selected subcategory ranks appear as dashed lines.

Use “Add KPI” in the “Product KPIs” bar to compare product metrics with the rank history. For the parent, Product KPIs cover the entire product family. The rank history shows the parent rank if Amazon reports a separate rank for the parent.

Under “Chart settings” you can show events with the event labels and put KPIs that share a unit on one axis. Owners and Admins add a custom event for a day by selecting a point in the chart.

What the BSR Explorer does not do ​

  • The BSR Explorer shows stored daily readings, not a live copy of the Amazon product page.
  • Through the MCP server, get_bsr_ranks returns the latest rank with the change over about seven days and the revenue of the last 30 days, independently of the period selected here.
