The social network said in a Facebook for Business post that the carousel format for mobile app ads will support up to five images, with links, adding that advertisers using the format have seen costs per conversion 30 percent to 50 percent lower than single-image link ads and costs per click 20 percent to 30 percent lower.
Facebook also said early analysis shows that the new format has helped boost click-through rates by an average of 12 percent compared with carousel ads when advertisers let the social network automatically optimize their order of images.
Mobile app install ads and engagement ads in the carousel format are now available via its ads application-programming interface, and the social network offered some examples of the use of the format in the Facebook for Business post:
