Yes, if you buy actual active Instagram followers, you'll almost certainly see a boost in interaction. To begin with, active Instagram users will always give options for your content to be interacted with. When you remove the bots and spam accounts, you'll be left with a high-quality list of followers who will help you enhance your interaction.
It is also up to you to determine how effectively they engage with you. To begin, you must ensure that you are providing the material that invites people to participate. This implies that you create interactive stories, quizzes, and polls on your postings, among other things.
