Meta offers several ad formats — single image, carousel (multiple swipeable images), video, and collection ads — each suited to different goals and products. This lesson covers choosing the right format based on what you’re promoting (e.g. carousels work well for showcasing multiple products), along with selecting the most effective call-to-action button (like “Shop Now,” “Learn More,” or “Sign Up”) to match your campaign objective and make it clear what action you want the viewer to take.
