A large furniture retailer wants to launch a conversion campaign using a mix of images and videos that highlight their line of modern furniture without a product feed. What ad format and KPI metric meets the retailer’s goal? (select one)

The selected answer is correct because Collection ads are uniquely designed to display a multi-asset experience—featuring one large "hero" image or video above three smaller secondary assets—which can be created manually without the need for an automated product feed or catalog. Since the retailer wants to highlight a specific line of modern furniture using both images and videos to drive a conversion campaign, CPA (Cost Per Acquisition) is the most appropriate KPI metric as it allows the advertiser to optimize for and measure the cost of specific bottom-of-funnel actions, such as purchases. While Showcase ads also support multiple cards, Collection ads provide a more integrated mobile-first storefront experience that is specifically recommended for retailers aiming to drive product discovery and sales.
