To get a good idea of how the carousel format can help boost the performance of a campaign, you can run a test:

1. Create two ad sets in one campaign. One should have three to ten ads with different images or videos in the single image format. The other should have an ad in the carousel format containing the same three to ten images or videos.
2. Ensure that everything about the ad sets is as similar as possible. They should have identical budgets, bids, targeting and landing pages.
3. Run the campaign.
4. Create an insights report and compare the metrics relevant to you for each ad set.
