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 several products, services, or features. This format enables a more comprehensive story to be told, as users can swipe through various cards, each potentially linking to a different product page or offering more details. While driving users to a specific landing page is a general goal of most ads, it's not unique to carousels; carousels specifically enhance this by offering multiple landing page options within one ad. Creating interactive polls and showcasing user-generated content are functionalities typically associated with other ad formats or organic posts, not the primary purpose of a carousel ad.
