Which shopper engagement will trigger charge for Auction Banner Ads campaigns in most cases?

The selected answer option is correct because, in most cases, Auction Banner Ads campaigns are charged based on impression. This means that advertisers pay when their ad is displayed to a shopper, regardless of whether the shopper interacts with the ad by clicking or making a purchase. The impression-based pricing model is typically used for display ads like Auction Banners, where the goal is to increase brand awareness and visibility, not necessarily to drive direct conversions. By charging for impressions, advertisers are paying for the exposure their ad receives, making this an effective strategy for reaching a wide audience and generating interest in their products or brand.
