IMHO Facebook ads are a black hole you an I may never recover from.
I am not saying Facebook Ads have no value, they do! It is just that they have become a massively sophisticated platform that we simply do not have the skill set to effectively manage.
That is you and I, the average content creator.
Too many of my online colleagues will encourage you to take a course to unlock the power of Facebook ads and manage your campaigns yourself.
More of my humble opinion........BAD IDEA! Listen to learn why!
