What is BSR?

Best Sellers Rank (BSR) is Amazon’s way of ranking products based on their sales performance within a specific category.

• A product with a BSR of 1,000 means it is the 1,000th best-selling item in its category.
• Rankings are dynamic and update frequently, especially for products with higher sales volumes.

Because Amazon categories can include thousands (or even millions) of items, raw BSR numbers can sometimes be difficult to interpret at a glance.

Why Productchimp Uses BSR Percentiles

To simplify analysis, Productchimp converts BSR into a percentile format. This helps you instantly understand how a product compares to others in the same category.

• Lower percentile = better performance
• Higher percentile = lower relative sales performance

Example:

• A product with a BSR percentile of 3% is in the top 3% of best-selling products in its category.
• A product with 0.00%, as shown in the image, indicates extremely strong sales performance.

Where to Find BSR in Productchimp

You can view BSR in the Ranks & Prices section of the product panel.

Here’s what you’ll typically see:

• BSR (Top %) – Displays the product’s ranking as a percentile
• Additional pricing data such as:
  • Buy Box price
  • Amazon price
  • Lowest FBA price

This placement allows you to quickly evaluate both demand (BSR) and pricing competitiveness in one view.

How to Use BSR for Product Decisions

1. Identify High-Demand Products

Products with a low BSR percentile (e.g., under 5%) generally indicate strong and consistent sales.

2. Compare Within the Same Category

Always evaluate BSR relative to the product’s category, as competition levels vary widely.

3. Combine with Other Metrics

BSR should not be used alone. Pair it with:

• Estimated sales
• Profit margins
• Competition indicators

4. Monitor Changes Over Time

Since BSR updates frequently, tracking changes can help you:

• Spot trending products
• Identify declining demand

FAQs

Does a low BSR guarantee high sales?

No. While a low BSR indicates strong relative performance, it does not guarantee future sales. Market conditions and competition can change quickly.

How often does BSR update?

BSR updates frequently—sometimes hourly—especially for high-selling products.

What is considered a “good” BSR percentile?

Generally:

• Top 1–5%: High demand
• Top 5–20%: Moderate demand
• Above 20%: Lower demand

Why use percentile instead of the actual BSR number?

Percentiles make it easier to understand performance across large categories by standardizing the ranking.

Can BSR vary between categories?

Yes. A product may have different BSR values depending on the category it is listed in.
