There are two types of keywords on Amazon. Targeted and negative keywords. The ones you want your product to show up for are called targeted keywords. At the same time, you can easily “tell” the platform for which keywords you do not want to pay for. This means that once you enter negative keywords to your campaign, the system will not show your ads when a user is searching for that keyword on Amazon. Negative keywords can be more or less restrictive, depending on their match type. Exact match type negative keywords are less restrictive, meaning that Amazon will not show your ad for that specific phrase in that specific order. Phrase match negative keywords are more restrictive because they will prevent all similar search phrases from triggering your ad.
