What benefit does are marketing list have for a Smart Shopping campaign?

A remarketing list allows Smart Shopping campaigns to target users who have previously interacted with your website or app. These users have already shown interest in your products, making them more likely to convert again. Smart Shopping campaigns leverage machine learning to optimize bids and ad placements for these high-value audiences, aiming to maximize conversion value. The other options are incorrect because: Smart Shopping campaigns do not use keywords in the traditional sense; they rely on product data feeds and machine learning. While remarketing can target past customers, it doesn't specifically identify those who made in-store purchases unless that data is integrated into the remarketing list. Smart Shopping campaigns primarily focus on online sales, not exclusively driving in-store traffic based on local product interest.
