ASIN merging is only one of several strategies manufacturers (vendors) may use to combat illegal Amazon merchants.
By consolidating duplicate listings, merchants may improve their market placement on Amazon and discourage illegal sellers from having their items shown alongside brand-name products on the SERP.
The primary purpose for merging ASINs is to retain brand protection. This technique can assist companies in their battles against illegal vendors who violate their MAP agreements.
ASIN merging is an advantageous approach for Amazon sellers seeking to protect their brand from illegal sellers or to clean up their catalog listings.
