The answer is simple. When you buy a house do you not first have a home inspection?
When you go to have your car worked on do they not almost always give you a multi-point inspection?
They don't inspect only one part of your home, a home inspection inspects the entire home before you buy it.
The dealership doesn't inspect just one part of the car, a multi-point inspection inspects the entire car.
The reason is because you don't always know where the problem is and at other times you don't always know where things are going well. Your business is no different.
You need to fully audit, you need to fully inspect your social media content creation strategy so that you can best understand who your target audience is, why they're your target audience, and most importantly you can get your content in front of the right eyes at the right time.
