Many people use Instagram as a pure marketing platform when it actually should be used for nurturing and building a relationship with your community and audience. It's a great place to show off your expertise and personality but is harder to start off building a community or audience because of its fluctuating algorithm. I encourage you to focus on bringing more people from your other platforms to your Instagram so they know more about you, get educated, and see your personality. Don't build your entire business on it and be sure to use your full traffic ecosystem so it does its job of nurturing.
