Facebook’s Business Manager is kind of like your toolbox. It essentially ‘holds’ your assets inside, like your Ad Account, Business Page, and Pixel. You can give people access to particular assets, or to the entire Business Manager. Creating this setup and organization is the first step.
If you’ve tried running Facebook ads based on audience interests, it can be kind of fun. Searching for things that might target your customers, thinking like they do, and getting that needle in a haystack. Until of course, you run ads and nothing works :/.
