What type of ad format did the advertiser use to design the ad below?

The advertiser used a Standard ad format. Standard ads feature a single image or video, which is the most common and basic ad type on Pinterest. This format is effective for showcasing a specific product, service, or idea directly. Idea ads (formerly Story Pins) are multi-page formats that combine images, videos, and text, offering a more immersive experience. Carousel ads display multiple images or videos that users can swipe through within a single ad unit. Collections ads combine a hero image or video with several smaller product images below it, designed for product discovery. Since the ad presented shows only a single, static image, it aligns with the definition of a Standard ad.
