@RMMulder Hi RMMulder, I did not even know I'd reach that rank, so I'm not sure what I did to get there.
The first advice I'd give is 'don't look at the ranking' or at how engaged the readers are. unlike Royal Road, readers here don't seem to be interested in interacting with the writer. in over close to 200 chapters, I can count on two hands the number of times I've had actual interactions with a reader here.
after that, I'd say it's the same as with other places, write a good and compelling story, clean it up as best as you can, and post on a regular schedule.
I just write the story I want to read and I don't really look at anything else.
Hopefully, this helps in a small way
