Duplicate ASINs and split variations make product search and purchasing decisions difficult for customers. Creating duplicate ASINs or separating ASINs of the same model in multiple families is a violation of Amazon’s listing policies.
If you have ASINs in your inventory that match other ASINs on Amazon, you can inspect them in the Potential Duplicates page and avoid suppression by accepting or rejecting it as duplicate. Learn more about Suppressed Listings.
To avoid suppression of your ASINs identified as potential duplicates, follow these steps:
When Amazon identifies a potential duplicate ASIN, we will add the ASIN to the Potential Duplicates page in Manage Inventory. From the date an ASIN starts showing up on the Potential Duplicates page, you have 30 days to review and respond by following the steps above. If you do not provide a response on an ASIN on the Potential Duplicates page within its 30-day grace period, the ASIN will be suppressed from search as a duplicate. Once an ASIN is suppressed, the ASIN will not show up on the Potential Duplicates page. You can view all suppressed ASINs on the Suppressed page.
To reinstate an ASIN that has been suppressed as a duplicate, follow these steps:
To report other ASINs that are potential duplicates, see Merge Duplicate Product Pages.
Amazon supports only one product detail page for a given unique product in order to provide a positive shopping experience. In some cases, Amazon, or any given seller may incorrectly create two sets of variations for the same model of product, and that would be considered a split varition.
In order to correct the situation, you may request both sets of variations to be combined under one single parent. This process is Not the same as Merge Duplicate Product Pages. Merge implies the fact that there are two detail pages for the exact same product. Combining a variation is when, for example, different sizes and colors for the same model of product are separated in two (or more) parent ASINs, which causes multiple details pages that could be grouped.
For example, for the model of show Cole Haan Men’s Nantucket 2.0 Penny Loafer, there are two sets of families divided in two details pages:
These two sets of variations should be together for all the palette of colors to be available to the customer in one single detail page. Therefore, a combination of variations should be performed.
If you identify that your variations are split in different sets of families, please contact Selling Partner Support and report the situation.
