Pinterest Performance+ creative optimization ads can scale ads by auto-generating which type of ad formats?

Pinterest Performance+ creative optimization can automatically generate Shopping ads and Collection ads to help scale campaigns. Shopping ads display products directly from a catalog, making them highly effective for driving purchases. Collection ads group multiple products together, allowing users to browse a curated selection within a single ad unit. While Carousel ads (multiple images/videos in one ad) and Showcase ads (immersive, multi-page experiences) are effective ad formats on Pinterest, Performance+ creative optimization does not auto-generate these specific types. Instead, its focus is on leveraging product feeds to create scalable, performance-driven ad experiences.
