The main advantage of using the Facebook Ad Manager app is its ability to synchronize and manage multiple business accounts in one place. For digital marketers, the platform makes it easier to create and maintain separate accounts for each business, allowing them to manage Facebook advertising campaigns.
If you want to run a business with an ad account, you should point out that you need a page so that advertisers can access their page to post ads. If you use Business Manager to manage a Facebook page and an advertising account of the customer, then it is important to use the Request Access option to add a page option.
