Hihiii!! First of all let me tell you how glad I am that you wrote me, I’d love to give some tips!
To be fair I started writing in a niche sector (a fanfic) which helped me gain views and recognition. Finding a sector like that helps to draw in people that like a specific type of book, and from there you build up your base. It’s good to have a constant uploading schedule for you chapters as well, so people don’t give up on your book. If they have to wait too long for updates, they usually forget about the plot and stop reading all together. So I suggest you write some chapters in advance and release them in a regular interval.
TikTok did help with additional views, but it was not my main source. I only started an account after writing my second book :)
Having a good description of your book is one of the main things that you need to look out for as well. Add tags to it so that people who usually read that type of book get it as suggestions. For example I had “abused” as a tag and my story was in the top suggestions for quite some time as more and more people get drawn to it. Was that clear?
I hope that helped so far, let me know if you need more information or clearing up, my Angel!! Xx
