A carousel is a multi-slide social media post that lets people swipe through several images, videos, or graphics.
Carousels are often used for tutorials, product highlights, before-and-after examples, checklists, and storytelling.
Because users spend time swiping through each slide, carousels can generate strong engagement and save activity when the content is useful.
The first slide needs to earn the swipe, while the final slide should give the audience a clear payoff, takeaway, or action.
Use as many slides as the idea needs, and no more. Many strong carousels land between five and ten slides, with the first slide earning the swipe and the last delivering a clear takeaway or call to action.
Each swipe counts as interaction and adds time spent with the post, which are strong signals to ranking systems. Some platforms also reshow carousels to the same person starting from a different slide.
Instagram, LinkedIn, Facebook, TikTok, and X all support multi-image or multi-slide formats, though the mechanics and slide limits differ by platform.
