Facebook introduces new advertising options on Reels and Stories
Facebook is introducing new advertising opportunities for brands across Facebook and Instagram, including the trial of ad on Reels.
Reels ads will begin testing in Australia, India, Brazil and Germany and will be similar to ads in Instagram stories in running for a maximum of 30 seconds and taking on a full-screen format on mobile.

Users will be able to like, view, save, share and skip Reels ads like they would with organic Reels content. The ads can be served in most places Reels are shown to users; through the Reels tab, Reels in Stories, Reels in Explore and Reels in the feed.
