Zhang wants to advertise wicker baskets and wants to prevent their ads from appearing on irrelevant shopping results. Which targeting method should they use?

Negative keyword targeting prevents ads from showing for specified search terms. In this case, Zhang can add irrelevant keywords (e.g., "plastic baskets," "metal baskets") as negative keywords to ensure their wicker basket ads only appear for relevant searches. Negative product targeting is used to prevent ads from appearing on specific product detail pages or categories, not for search terms. "Negative product match" is not a standard Amazon Ads targeting method.
