Finding readers for my published NewAdult/YA romance novel.?

[TheBellJar]

arjun Amazon does not do any promotion for self published books, not one thing, That's why it's called self publishing you have to do everything yourself, but most publishers don't do much for their authors either, unless they have hit the big lists already, and that's why they are losing a lot of authors to Amazon. (One of the reasons.)

You are right though that spending money on advertising rarely works for authors. Most of the people I know who have tried it spent more than they made and were pissed off.

OP you sound like you are doing pretty much all you can do, you just have to find ways of doing it more effectively. One way I know is to just spend time talking to people. I don't actually do enough of it, but just sitting on social networking sites without interacting doesn't do anything.
