To start creating and running ads on Instagram, you need an Instagram account. Whether you are creating a new account or already have an existing account, you can add it to your Business Manager to run the ads. Alternatively, you can connect your Instagram account to your Facebook page. If, however, you do not have an Instagram account and have no intention of creating one for your business, you can use your Facebook page to be the face of your Instagram ad. This page-backed Instagram account means that you will not have to create a separate Instagram account that will be rendered useless once the ads run their course.
