Amazon is a competitive marketplace—as much competitive as it can get.

In such a cutthroat environment, it is paramount for every seller to keep an eye on competitors and carry out extensive product research before entering any product category. 

ASIN lookup or reverse ASIN lookup powered by a specially designed tool is an effective way to do that.

However, many such tools don’t yield the desired results. For instance, some of them can’t fetch the accurate data of a given ASIN. Another shortcoming of many such reverse ASIN lookup tools is you can’t find out the KPIs of multiple ASINs all at once. 

If you want to know how to carry out bulk ASIN lookup, then look no further. 

In this step-by-step guide, we will share with you how it is not just possible but also very easy and swift to conduct a comprehensive bulk ASIN lookup.

How to Do Bulk ASIN Lookup within Five Minutes? 

You will need an effective bulk ASIN lookup tool to analyze multiple listings at once— a tool that can provide you with a 360-degree insight into all the listings. 

Sales Spy is one such tool where you can run your analysis on a bulk of competitors’ listings in a go to find their estimated sales, revenue, and profits. 

Sales Spy is part of ZonGuru’s seller toolkit. First, log in to your ZonGuru account and open Sales Spy from the side menu bar (under the Product Research drop-down).

Start adding the ASINs you want to look up in the search bar (separate them by space or comma). Also, select the duration for which you want to fetch the data. Besides last week, last 30 days, and last one year, you can also set a custom range. Lastly, select the marketplace (US, UK, Germany, etc) for which you need the data. 

After putting all the ASINs you want to analyze, click the +Add button to get the bulk searches.

At a glance, you can see all the important data points for all the ASINs you want to monitor. Scroll down and see the numbers for your entire bulk of listings.

Let’s break down all the data you get in this bulk ASIN lookup. 

  • Price: The price of an individual unit in the selected time period (30 days in this case).
  • Sales: Everyday unit sales for the selected time period.
  • Revenue: The revenue for the selected time period along with the daily breakdown.
  • Estimated Profit: The estimation of the profit at a 30% net margin for the selected time period along with the daily breakdown.
  • Rating: Average ratings the ASIN has received in the selected time period. 

The Action tab at the end of the row has two buttons: Graph and three dots.

By clicking the graph icon, you can get multiple data points for each ASIN of the bulk.

In the first raw, you find out when the ASIN was established on Amazon. This information lets you know how strong the foundation of the given listing is. Then, you can see its current BSR and how many sellers are listing for the same ASIN.

Then, there’s a graph where revenue, sales, and BSR are plotted against the selected time period.

Next, there is a “three dots” button. From there, you can either download the data as an excel sheet or delete the ASIN entry from the tool.

As demonstrated in the above discussion, you can find revenue, sales volume, and estimated profit of multiple ASINs in a single go through Sales Spy.

An ASIN with eight sellers already on it implies tough competition for any new seller

An ASIN with three sellers mean one can consider it for their retail arbitrage or wholesale gig

Importance of Bulk ASIN Lookup Tool for Agencies/Enterprises

A bulk ASIN lookup tool is a godsend for entities that are managing multiple listings under several brands and seller accounts. Handling multiple ASINs with every ASIN having numerous competitors, it can get quite overwhelming to carry out a competitor analysis for every listing.

With the help of a suitable bulk ASIN lookup tool, those Amazon agencies can conduct complete competitor analysis of any listing within a couple of minutes. Just as shown in the above section, you can find sales, revenue, and optimized keywords of dozens of ASINs in not more than 1-2 minutes. 

This robust lookup feature comes in really handy when you have to do in-depth competitor analysis for dozens of listings within a single working day. 

Besides competitor analysis, an intuitive bulk ASIN lookup tool can also help agencies and enterprises in viewing the data of their own ASINs more conveniently. For instance, you can see the sales volume, revenue, and BSR of your listings from one window instead of going down the rabbit hole of Seller Central.   

You can review all the sales and revenue data of bulk ASINs at a glance rather than mining loads of data available across gazillions of Seller Central business reports.
