For me I gained a bit of a following as I was producing new chapters for one of my fanfics (YCCiP to be specific) and I guess in my case it appealed to the audience I had because of the background it had, which in YCCiP’s case, was FNaF. But generally, I think it all comes down to blurbs and narrations. What you have right now is currently fine, but if anything, make them a little bit longer and reveal a tiny bit more about the story. It’s just a suggestion, you can keep yours the way they are if you want :3
I guess for attracting an audience, they would be willing to read books that appeal to them, right? So just wait, and you’ll get yourself a following of people who like your story concept or your writing style that may be willing to read more of your works!
In conclusion, try to make blurbs attract a little better and just be patient!
