90% of the battle feels like it lies in getting yourself out there and promoting yourself wherever you can (Like here, in other forums, on social media and so on)
I'm currently struggling myself, along with my artist, to just get those few extra views and subs, while I check the stats obsessively every day. It's not healthy xD
Some do have luck and gets discovered quite quickly with the rest of us just having to learn the hard way 
A good idea would be to post your link in your post, as it wouldn't be out of place, and would give people the opportunity to check it out, and maybe give you one or two followers.
(Like I'm shamelessly doing with mine now):
