Collection
Instagram Reels


Instagram Reels enables people to create entertaining short-form videos with editing functionality, music and effects. Instagram Reels ads are full-screen, vertical ads that can appear between organic reels.
You can use the collection ad format in Instagram Reels to include a cover image or video with up to 3 smaller product images below it arranged in a scrollable, horizontal layout. When someone taps on the cover image or video, a full-screen Instant Experience will open and enable them to discover, browse and purchase products and services on their phone. When someone taps on the smaller product images, product detail pages provided by you will open to encourage purchase on their phone.
