If you're not already, I recommend to just keep doing what you're doing now, which is interacting with other authors. Keep making yourself visible. As you do this, you will gain followers who will help you be more visible by commenting on and resteeming your posts so their followers can see them.
For the first little while, it's like trying run up a bit of a steep incline, but keep going and give it time and you'll start seeing the rewards. ;-)
