What is a Facebook Ads agency?
A Facebook Ads agency (also called a Meta Ads agency) is a firm that plans, manages and optimizes its clients' advertising campaigns on Facebook, Instagram and Messenger from Meta's Ads Manager: it chooses the audiences, produces the creative, sets the budget and measures the sales the ads actually generate.
Facebook and Instagram both belong to Meta: a single campaign runs in the feed, Stories, Reels and Messenger on one budget. The work of a Facebook Ads agency is therefore less about picking the network than about three levers: the audiences, the creative and the quality of the sales signals sent to Meta (Conversions API).
