It's really sad to say, boys are the only way to get new people to discover you on IG. The way IG works now is based on monetizing for advertising. So it actively works against their user base to minimize the ability for its users to organically gain new followers. They do this so you now rely on purchasing ads to gain followers. Pic related is impressions (basically means how many people see the post) notice only about 1-2% of all the views come from hashtags, that's next to nothing. I bot my account and that's really the only guaranteed way of gaining new followers without spending money unfortunately.
