A conversion ad is especially well suited for eCommerce. It is designed to target potential buyers, and not just 'window shoppers' or browsers who may visit your site, but are unlikely to make a purchase.
Unlike dynamic product ads, conversion ads that use catalogs do not automatically show users the products they've already engaged with (since the ads may also be shown to cold, or new audiences). However, Facebook does use the data it has on its users to show them products they are more likely to click on, based on their browsing history and preferences.
A conversion ad can be created in any of the following formats: video, single image, carousel, or collection.
Finally, in conversion ads, you can set up multiple ad creatives in a single ad set or campaign.
