Platform term. Also written swipe post, multi-image post.
Introduced by Instagram in 2017 as multi-image posts and adopted since by LinkedIn, TikTok and others. The name comes from the horizontal rotation of the slides.
Rewards a reason to swipe: the first slide has to earn the second. Common structures are before-and-after, step-by-step and a list with one point per slide. Platforms often measure swipe depth, so a carousel that holds attention across slides can outperform a single image on the same content. LinkedIn document posts work the same way.
Safe and purely descriptive. The only real trap is making a carousel with no reason to swipe, which performs worse than a single well-chosen image.
One post containing multiple images or videos that the viewer swipes through.
Enough that each earns its place. Most platforms allow up to ten or twenty, but engagement usually depends on the first two.
Often, because swipes signal engagement. It depends entirely on whether the content gives a reason to keep swiping.
