Which platform can be used to set up a Facebook ad campaign?

Ads Manager is the primary tool used for setting up, managing, and analyzing Facebook ad campaigns. This platform provides a comprehensive suite of features that allow marketers to create tailored advertisements, define target audiences, set budgets, select ad placements, and monitor the performance of campaigns through detailed analytics.

While Business Manager is a valuable platform for managing multiple ad accounts, Pages, and permissions, it serves more as an organizational tool rather than a direct interface for creating ad campaigns. Content Creator is focused on content development and publishing, not specifically on advertising. Page Insights provides analytics and performance data about a Facebook Page but does not offer functionality for setting up ad campaigns. Therefore, Ads Manager is the most appropriate and functional platform for creating Facebook ad campaigns.
