When conducting product research, one of the most important parameters to evaluate is demand. How? spy on the competition.
There are lots of software that can help you figure out how many units of a product are sold.
One of the most widely used tools is definitely Jungle Scout. But lately. Helium 10 Is considered a must-have.
The problem is that the data of Jungle Scout are based on estimates, which in the case of low-volume products are not very accurate.
JungleScout | Sales | % difference | |
Product 1 | 97 | 99 | +2% |
Product 2 | 67 | 73 | +9% |
Product 3 | 143 | 161 | +13% |
There is a trick, however, that is 100% accurate for spy on the competition on Amazon FBA.
It is very simple to find out how many products are being sold: just put the product we are interested in monitoring in the cart, set the quantity to 999, and Amazon will give us an alert telling us how many units of the product are in stock.
After a week you can do the same operation and we will have an estimate of how many products the seller manages to sell each week.
This sounds like a tedious operation: can't it be automated?
Fortunately, there are tools that allow us to automate this process, which is very useful if we are monitoring several products.
Fortunately for us Sellics offers this possibility. In fact, the tool will perform the operation in an automated manner every single day giving us an accurate estimate of the units sold.

It should be emphasized that this trick does not always work. The seller may have put a cap on the number of items that can be purchased, so in some cases it will be impossible for us to know the actual stock in the warehouse.
However, there are various tools for Amazon FBA who can make estimates of products sold, which although they do not give certain data, are quite accurate.
The importance of analyzing competition is extensively explained in the Amazon FBA course.
