What do carousel ads allow advertisers to do?

Carousel ads are designed to showcase multiple images or videos within a single ad unit, allowing advertisers to highlight various products, services, or features in one cohesive ad. This format is effective for storytelling or presenting different aspects of an offering, as users can swipe through the cards. While carousel ads can drive users to a specific landing page, that's a general function of most ad formats, not their unique defining characteristic. They are not primarily for creating interactive polls or exclusively for showcasing user-generated content, although UGC could be incorporated into a carousel.
