The purpose of the analyzer tool is just too narrow down the list into profitable products, but you will still want to go through yourself and analyze each product individually. So, you would start with the first product and use the FBA fee calculator to determine the profit, then you'll go to the listing and check out the sales rank, the competitors, the Keepa graph, etc. So, the tool results are not an end all solution to just order the products. It is a shortcut to narrow the list down, so then you know which ones to dive deeper on.
We recommend going through each of these products and doing in depth research on them by following the methods in the Product Research section of the course.
Do analyzer tools do all the analysis for me?
Can I trust the numbers that come out of the ASIN Scanner?
