Product launch ads are a great candidate for the image or carousel ad template. Use it to tell a story about the making of a new product and highlight different aspects of it, either through high-quality, featured image or a series of images in your carousel. The copy for these ads should drive home the real-world value your new product or service provides. Make Facebook users as excited for the release as you are!
While carousel and collection ads are the obvious choice for these kinds of situations, a dynamic product ad or Instant Experience ad can also work well. Regardless, when featuring a set of products, make sure that each one is visually distinct from the other and includes its own headline and CTA (which should be specific to the individual product).
