Ok so, I am not new as an author, my novel is about 7 months old
My views and reader rate has slowed down considerably and I want to know is there any way to get more attraction, keep the retention without having to go to threads and chats to advertise my novel? And also without having to post 50 chapters a week?
Well, you have 4 options.
1. Chap tricks. This is the sort of thing everyone has been recommending so far.
2. Throw money at it. In other words, buy advertisements.
3. Get gud. This would be just becoming better at writing and making something that's actually worth the views.
4. Exploit the system. Most of the exploits on SH have been closed, so you are going to want to find a newer site if you want to use this one.
My personal recommendation is to just use option #3 and consider your current story a practice run. I've taken a peek over at it, and honestly, there are several points that are lacking. The title has nothing interesting to it, your synopsis seems like you are being edgy just for the sake of being edgy, the cover reeks of Chunibyo, and your opening paragraph in chapter 1 lacks a strong hook.
Paragraph 1 sentence 1 of your series is live or die for the entire work, and you spent it talking about pastel shades of blue. There's absolutely nothing interesting in talking about the color blue.
It's a good effort to learn the lay of the land in the writing world, but I'm afraid this story doesn't really have much of a future in the long-run. I would encourage you to continue it anyway, just for the sake of gaining some experience. I had been writing for 8 years before I even started posting publicly. During that entire time, I was learning. Even still, once I started posting publicly, I noticed my writing ability increase several times faster than during my 8 years of practice.
Just keep at it and keep your schedule consistent. You will get better eventually. Once you do improve your skills, start over with a new series once you're able to better apply your writing skills.
