The carousel ad format is available for Facebook, Instagram, Messenger and Audience Network, and allows you to showcase up to 10 images or videos within a single ad, each with its own link. With more creative space within an ad, you can highlight different products, showcase specific details about one product, service or promotion, or tell a story about your brand that develops across each carousel card.
