Find out and compare Amazon Sellers tools chrome extensions. But what those extensions are for?

For remind, those extensions often allow Amazon Sellers to detect and find a product opportunity browsing in 19 Amazon Marketplaces among over 350 million products.


When introducing Amazon, we cannot miss this company is a giant tech company with Global Marketplaces which are United States, Canada, Mexico, United Kingdom, Germany, France, Italy, Spain, Japan, Singapore, United Arab Emirates, Brazil, Australia, India, Netherlands, Saudi Arabia, Turkey, Sweden (new in 2020), Poland (new in 2021). Undoubtedly Amazon is the biggest online retail market and includes over 350 million products…

But how this colosal number of products is referenced and sorted?

Firstly, an unique ASIN (Amazon Standard Identification Number) ISBN (International Standard Book Number) based on UPC identify each product. Secondly, on Amazon, products are also sorted by category and several levels of sub-category.

Indeed, the 26 Amazon’s categories and sub categories are:

Obviously, these chrome extension use several criterias to calculate an indicator or produce an analysis on all Amazon products or in a part of Amazon catalog.

Criterias are at least the following:

At last let’s see the offers of 3 competitors (, Jungle Scout and Viral Launch)

Already we cannot miss that this Chrome extension have an LQS indicator for each product and allow to download product review with filters in CSV format.

LQS indicator means Listing Quality Score and include 3 sub indicators with different weights in total as following:

Conclusion: this chrome extension is more to improve Listing Quality but it does not allow to detect product opportunity

When opening, this chrome extension includes for each product 5 parts presented in 5 tabs:

Jungle Scout

When browsing in Amazon, we notice Jungle Scout extension fits really well to page.

Also, we can track product. Moreover without launch extension we have already an insight of product datas as monthly/daily sales, ASIN, LQS, Net, Fees, Dimension, weight.


When launching extension, in one glance chrome extension provides 4 important informations on the product, average monthly sales, Sales Rank, price and Reviews.

On extension we also find a menu:

Conclusion: Jungle Scout presents a lot of product datas but in one glance is it good deal? But, we don’t know we have to deepen search and compare maybe thanks to tracking.


Scoring of competitors extensions


[table id=1 /]



To conclude, I think graphically and Jungle Scout extensions fits well to Amazon marketplace page ( However is not a decision maker tool to find product opportunity to sell.

When regarding listing improvement, is the best extension. Otherwise, Jungle Scout extension is the most complete product and get the best scoring.

Finally, Jungle Scout and Viral Launch allow to track products, it’s a very interesting feature to not loose time.

But my preference of Amazon starter seller go to Viral Launch which is the only tool to produce analysis on potential product opportunity. Obviously, this feature is essential to launch products on Amazon.
