Amazon may contain multiple listings for the same UPC/EAN Product ID. By default, Analyzer.Tools will return ALL listings that match your Product ID which may result in multiple results for the same UPC/EAN. Viewing all matches can be useful when analyzing your potential product’s viability vs. other listings of the same product as competition.
You can specify to return only the top matching results by Sales Rank in the Duplicate Product Listings section of Processing Options as shown below.
