How to estimate Amazon product sales

First, add the listing you are referencing to the shopping cart, then set the order quantity to the maximum quantity of 999. If the other party's inventory quantity is less than 999, you will be prompted with the number of items available for sale (as shown below)

This way you will know the current inventory quantity of the listing. Repeat the above steps the next day for one or two weeks, and average the recorded data to roughly know the average daily sales of the listing.

However, since the review statistics and display start from the time the listing is put on the shelves, the data from three years ago is not very relevant. It would be better to use the last three months or six months as the time node and only count the data within this period, which will be closer to the truth.

According to experience, on the US site, if a store's sales are basically stable, then 4-5 times the number of feedbacks in the store in 30 days is equivalent to the number of orders in one day. For example, in the figure below, the number of feedbacks in the store in 30 days is 126, multiplied by 5, the number of orders in the store per day is about 600.
