Hi,
Building a reader base can be slow.
Things I've learnt on here.
Update weekly.
If you start a book, have at least half the chapters written in drafts.
Have a beginning middle and end in mind for the book.
Pick a genre to write about and tag accordingly.
EG. Supernatural, romance, thriller......
Follow writers that write in your genre and their readers to begin with, to build a reader base.
There is no fast track on here I found, you just have to keep writing.
Good luck.
