A fashion retail advertiser wants to showcase their new TV ad and promote their full product catalog to generate sales. Which ad format should they choose?

The selected answer is correct because Collection ads are uniquely designed to bridge the gap between brand storytelling and direct commerce by pairing a high-impact "hero" asset—such as a video of a TV ad—with a row of three smaller, secondary product images pulled directly from a product catalog. When a user interacts with the ad, it expands into a full-screen, immersive mobile experience that can display up to 24 additional shoppable products, allowing the retailer to use their premium video content to capture attention while simultaneously providing a direct path to purchase for their entire inventory.
