What ad format is most suitable for showcasing multiple products in one advertisement?

The carousel ad format is particularly effective for showcasing multiple products within a single advertisement. This format allows advertisers to include several images or videos that users can swipe through, making it ideal for presenting a range of products in a visually engaging manner. Each card in the carousel can highlight a different product, feature, or aspect, providing an interactive experience for the audience. It encourages users to engage with the advertisement by navigating through the various options, which can lead to increased interest and potential conversions.

While other formats like slideshow and collection also have their merits, they do not provide the same level of interactivity or product exposure as carousel ads. A single image is limited to one product at a time and does not take advantage of the potential to showcase a variety of items, which is a significant strength of carousel ads.
