The plan is how many people will interact per day and how many new people will be follow per day...
As example,
If you could follow 15 a day thus you follow 450 people a month. And if you did well with your interaction, you'll get at least %20 follow back, it mean that you'll around 90 new followers a months.
What is the specific time for working with social media interactive 30 or an hours a day..
Who should you interact with them, and how to interact with them..
Please ask yourself, "Why does people love to talk with you on Intagram?" and "How"
I hope it helps..
