Which ad format allows advertisers to showcase multiple images and videos within a single ad unit?

Carousel ads are specifically designed to allow advertisers to showcase multiple images and videos within a single ad unit. This format is interactive and lets users swipe through a series of images or videos, each potentially linking to different destinations. This capability engages users more effectively by providing a richer storytelling experience and giving advertisers the opportunity to highlight various products or features in one cohesive ad. The interactivity of carousel ads often leads to higher engagement rates compared to static formats, as users can explore multiple visuals without having to leave the ad.

Other ad formats, such as single image ads and video ads, are designed to present just one image or one video at a time, thereby limiting the ability to showcase multiple visuals simultaneously. Slideshow ads, while they can display multiple images in a dynamic format, are generally less interactive than carousel ads, since they automatically transition through the images and do not allow users to control the experience. This makes carousel ads the preferred option for those looking to utilize multiple images and videos effectively within a single ad unit.
