Business ads manage is strictly for managing and creating ad campaigns. When you’re in the ads manager, you can select which individual ad account you’d like to view under your profile or your agency’s profile depending on who owns the ad account. For example, if your agency is an ad account owner, you can add business profiles under that account and create their own ad account under your agency’s. In ads manager, you can also check out ad campaign reports, which are super handy when you’re discussing ad performance with your clients.
