The time has come to talk about one of the most crucial points of data in the Amazon ecosystem. What am I talking about? The Amazon Best Sellers Rank.

This single datapoint is crucial to sellers of all types, from retail arbitrage to wholesale and even private label.


Because it gives us an incredible insight into sales velocity, trends, and overall competitiveness of an item.

And it’s one of the only data points we can rely on to do so.

Today, we’re going to dive into exactly what the Best Sellers Rank is.

Then, we’ll talk about some tips and tricks to boost your product’s BSR, and a few comments about top-level categories.

Understanding the Amazon Best Sellers Rank

Before we talk about analyzing the Best Sellers Rank, we’ve got to describe what it is.

In essence, the BSR is the product’s sales velocity compared to other items in its main category.

There are, at the time of this writing, over 30 main categories on Amazon.

So, if a SKU has a BSR of say, #4,235 in Tools and Home Improvement, it’s the #4,235th best selling Tool on Amazon, relative to other Amazon products in that category.

Estimating Sales Velocity

Now that we know how the BSR describes a product, it’s time to take a look into sales velocity.

Luckily, there’s quite a few tools that estimate this.

You can learn a bit more about estimating sales here, but in general, a tool will give you a quick estimate of the monthly sales.

To go back to my previous example, we can take a look at #4,235 in Tools. We’ll head over to JungleScout and enter that criteria:

JungleScout’s Sales Estimation Tool is great for quick, one-off checks of sales ranks.

And boom! We’ve got a good number of estimated sales for that rank. 1,320 units per month – not bad!

This isn’t perfectly accurate, but it gives a great estimate to go off of.

How to Rank Your Products Higher

Now that you know the power of the BSR algorithm, I’m sure you’re thinking, “This is all great, but how can I boost my product’s BSR?

There’s a lot of ways to go about this, many of which can be pretty complex. Here’s a few of the basics.

Enrich Your Listing

The first thing I’d recommend if you want to improve your BSR is enrich your listing.

Well, what does that mean exactly?

You want to make your listing keyword-optimized while also being conversion-optimized.

Try a tool such as this to hunt for some keywords. Are they in your listing’s description?

use tools like to hunt for keywords and boost your product's Best Sellers Rank is a great tool to hunt for those missing keywords, and optimize your listing.

Is your listing’s copy good? Great?

How are your conversion rates? I shoot for at least 10%. Likely, 20%+.

If they’re lower than that – either your ad traffic is poor, your listing is poor, your reviews are poor, or your product is poor.

These are a few things to keep in mind when editing.

You want to be in a nice sweet spot where your listing isn’t spammy looking, but fits in just the right amount of keywords.

Leverage A+ content where possible. Take into account customer reviews when making listing updates.

Make your listing incredibly clear to understand, read, and purchase! Make sure those listing bullets are tidied up.

Once this is all done, give your product a couple weeks.

Boost Your Amazon Best Sellers Rank with Amazon Advertising

I know, I know. Many sellers don’t like the idea of more ads.

But you can try this with a small budget.

Try even just $5 a day on some of those new keywords you just found.

Leave that running for a week or so. Find anything good?

Keep the keywords you like the conversion rate on. Drop the bids, or exclude the keywords you don’t.

Continue refining this week by week. You can even automate this if you’re feeling super lazy.

Subcategory Ranks

Sometimes, you may come across an item that straight-up doesn’t have a rank on the page, or maybe has a subcategory rank.

This can be a decent warning sign – often, products that don’t display a rank have one that’s so high, they’re probably not worth purchasing.

There are a few exceptions to this rule, however.

There are a few categories that ranks currently don’t display in, at least on some listings.

Clothing is one of these.

To make sure you’re keeping track of all sales ranks over time, try using a tool like Sellonaut. It’ll make your rank data clear and easy to filter and understand.

Graphing Trends

Now that we’ve gotten down the basics of the Best Sellers Rank, let’s leverage it to power our purchasing.

Any experienced Amazon Wholesaler will tell you that leveraging the BSR is absolutely crucial to purchasing criteria.

It tells us how fast something moves.

And eventually, over time, you develop a bit of a feel for the BSR. You’ll learn that #150,000 in Sports is maybe not worth your criteria, but #50,000 is.

However, to make this easier, we like graphing it out.

Here’s a few examples of sales rank graphs in Sellonaut.

Leveraging sales rank graphs and historical data is crucial for any Amazon wholesaler.

In these graphs, the sales rank, or BSR, is notated by the red line.

When the red line drops, sales are increasing.

When it goes up, the sales velocity is decreasing.

So, at a high level: Items with a consistently lower-level red line are selling a lot faster than a higher-average line.

We want to chase the averages here.

In Sellonaut, we’d add a filter based on the 90-Day BSR average. If I want decent, fast moving items, I add a filter for a 90-day average under #25,000, and profit over $1.

Then, I can setup daily exports based on my purchase criteria.
