Hey Yash, just say your message on the tab and thought to personally help you out. The thing is as new writers even we faced the lack of desired engagement on our books but with due time it effectively grew.
We are not yet good at giving tips but these certain tips might help you:
1. Search and add creative tags related to your book.
2. Reach out to different writers, to either ask for help/tips or to also promote your book (with their permission, if required.)
3. Try to maintain a consistency while posting the chapters. Especially the beginning ones, because the audience don't yet know the quality of your writing so it somehow becomes the writer's duty to earn that interest of the readers on our writing.
Hope it helped, all the best!
