How to check your Amazon Best Sellers Rank

Updated 10 November 2026

Open your product's listing on Amazon, scroll down to the product details and look for Best Sellers Rank. It's free, and you don't need any software or a Seller Central login. This guide shows you where to find it, what the number really tells you and how to use it to make better decisions.

Step by step

Open your product page on the Amazon site you sell on. Your rank is separate on each site, so Amazon UK and Amazon Ireland will show different numbers.
Scroll down to the product details. Depending on the product, this is called Product details, Product information or Additional information, and it can be a table or a list.
Find Best Sellers Rank. You'll usually see two or more numbers: one for a large category, such as Sports & Outdoors, and one or two for smaller categories, such as Water Bottles.
Click the smaller category name. It opens the best-seller list for that category, so you can see the products ranked around you.

Can't see a rank at all? That's normal for very new listings and for products with few sales. Amazon only shows a rank once a product has enough sales history in its category.

What the number means

A lower number is better: #1 is the best seller in that category. Amazon says the ranking is based on Amazon sales and updated frequently to reflect recent and historical sales. So it's a comparison with the other products in the same category, not a count of how many units you sold.

That has two useful consequences:

Your rank can move even when your sales don't. If a competitor has a big week, you can drop a few places without selling any less.
The same number means different things in different categories. #500 in a huge category can be far more sales than #50 in a small one. That's why there's no single "good" BSR. Here's how to judge yours.

Amazon also notes that it only shows a few of the most popular subcategories on each product page, so your product may sit in other categories you don't see listed.

Which number to watch

Your smallest category is usually the most useful one. Those are the products a shopper compares you with, and the products you're really competing against. The big category number is useful as a rough guide to overall volume, but it moves a lot with sales across thousands of unrelated products.

How to use it

Look at the trend, not one reading. Rank moves during the day. Check at about the same time each week, note the number, and look at the direction over a month.
Look one place above you. Open the category list and compare the product just above you: its rating, review count, price and images. That's often the clearest picture of what it takes to move up.
Connect moves to what you changed. Note price changes, new images, a promotion or a stock outage next to your rank readings. Over time you'll see which changes really move the number.
Compare like with like. Only compare ranks within the same category on the same Amazon site.

How to keep a record for free

A simple spreadsheet works well. Use one row per check, with the date, the Amazon site, your product, the category and the rank. Add a notes column for anything you changed. After a few weeks you'll have a trend you can trust far more than any single number.

What Best Sellers Rank can't tell you

It isn't your search position. You can rank well in your category and still appear low when shoppers search your main keyword. Here's how to check your keyword ranking.
It isn't your unit sales. For a real-volume signal, look for Amazon's bought in past month figure on the listing or in search results, where it's shown.
It doesn't explain why you moved. If you've dropped, this checklist covers the usual causes.

See it on the Amazon page instead

SellerRanks is a Chrome extension that shows your Best Sellers Rank, who is one place above you and what has changed on the Amazon pages you open. It's a one-time payment with no subscription, and it won't replace a full research suite. See how it works.
