A business manager is an extension of a social account that is linked to it and used to scale an advertising campaign.
There are three types of BM: Limit 50, Limit 250 and Confirmed by documents.
The only difference between them is the limit, but the BM confirmed by the documents is more valuable for Facebook and is less often blocked.
Restrictions on the frequency of using BM and reducing the number of locks do not have much effect. It is recommended to use the BM for those who already know how to run ads on Facebook without blocking and need to quickly scale the volume of advertising.
It is recommended to always have additional links to your Business Manager, since in case of blocking a social account, the created advertising on it will continue to work until the money runs out on the linked bank card.
It is not recommended to attach more than 5 Business managers to one social account (they should be attached with a break of 1 hour).
BM Acceptance Process:
Through the invitation link (the most common option). To do this, follow the link, enter the password from the social account and click the "Accept BM" button.
Sending an invitation by email (exactly the same process as in step 1, the invitation link will just be on your mailbox).
