Here are a few simple steps to help you reach out to influencers:
Start with interesting questions in your caption. This breaks the ice and gets the audience to respond to your question.
Follow other accounts that are in your niche for better reach and visibility.
Examine your competitor and follow the trend with your own twist.
Post stories that are engaging. Polls are a good way to kick-start your engagement.
Schedule regular live streams. Your followers would love to see you and it appears more personal as if they are included in the circle.
