A carousel is a Pin with multiple images. Carousels are a great way to showcase different features of a product, advertise multiple products at once, or tell your brand story in chapters.
People see the carousel in their home feed just like any other Pin. They can swipe through the different images (or cards) directly from the feed. Or, they can tap on the carousel and swipe through each card and its corresponding site, essentially swiping through the different landing pages. When someone saves a carousel, they save the entire Pin including all the cards within it.

Anyone with a Pinterest business account who’s in an ad market can create a carousel in Ads Manager or the bulk editor.
