These are paid ads that appear between regular product listings on Marketplace (mobile only), helping businesses reach more users where they’re already scrolling and shopping with purchase intent. While Facebook Marketplace paid ads appear among other relevant products, they are set apart by their larger size and a Sponsored label.
Facebook Marketplace sponsored ads are available through the Ads Manager, just like all the other ad formats. Advertisers design and create their own ad set, define their budget, and select an ad placement. Facebook recommends the Automatic Placements setting so that ads will appear across different placement options such as News Feed, Instagram, Messenger, Audience Network, and Marketplace.
Note: Marketplace ads also appear as News Feed ads, because it’s not currently possible for ads to only show in Marketplace.
