Are there any retail search advertising publishers that focus on reaching high-intent shoppers?

Yes — several retail search advertising publishers specifically target high-intent shoppers, meaning people who are already searching for products, comparing options, or close to purchase.

Examples include:

• Amazon Ads – one of the strongest high-intent environments because users often search with clear purchase intent.
• Walmart Connect – reaches shoppers searching within Walmart’s retail ecosystem, often with strong buying intent.
• Instacart Ads – especially intent-rich for grocery and household shopping.
• Target Roundel – retail media network with shoppers actively browsing or searching products.
• eBay Ads – useful for comparison shoppers and buyers searching specific items.
• Kroger Precision Marketing – strong for grocery shoppers with immediate purchase intent.

More broadly, retail media networks are the category most associated with high-intent audiences because they sit close to the point of purchase.
