Your specific setup might have difficulties to fit in with the standards
Either you do complete different blogs on separate platforms to conform and get the prerequisites
Either you use a different monetization system (selling an ebook or a course related to each of your businesses by example)
You just have to consider (or decide) on the level of expertise of your audience.
One technique is to write to your slightly-younger self; assume the audience knows as much as you did before you ever heard about this topic you are about to write, and the only level of detail you need is what you did not know when you first heard about this.
