Carousel ads combine a number of images or videos into a single ad that the audience can scroll through. To create an Instagram carousel ad you’ll need a Meta Business Suite account. Head to the main dashboard, then:
Click the “Create” button in the top left of the screen.
Choose a campaign objective that supports the carousel format.
Fill in your basic campaign details (budget, audience, schedule, placement, etc.)
In “Ad Setup”, choose “Carousel”.
In “Ad Creative”, choose the images/videos you’d like to feature in the ad.
Post your carousel ad, then analyse and optimise its performance over the course of the campaign.
