Highlighting multiple products: Companies can use carousel ads to showcase multiple products in a single ad, allowing users to swipe or click through to see more details and options. This can be an effective way to showcase a range of products, such as different colors or styles, and encourage users to make a purchase.

Telling a story: Carousel ads can also be used to tell a more immersive and engaging story about a product or service. By using multiple images or videos, businesses can create a narrative that captures the attention of users and helps them understand the value of what they are offering.

Offering special deals or promotions: Carousel ads can be a great way for businesses to highlight special deals or promotions that they are offering. By using engaging images or videos, companies can grab the attention of users and encourage them to take advantage of limited-time offers.

Driving traffic to a website or other online platforms: Ultimately, the goal of carousel ads is often to drive traffic to a company's website or other online platforms, such as an e-commerce store or social media page. By using engaging and compelling images or videos, businesses can entice users to click through to learn more and potentially make a purchase.
