Many factors influence the growth of a novel's readership, such as content, genre, tags, synopsis, cover, prologue, number of chapters, regular updates, promotion, and even luck.
Some novels have hundreds of chapters but still have less than 10,000 views and less than 100 bookmarks. Others have only a dozen chapters but already have 100,000 views and hundreds of bookmarks. There are cheat codes, such as using the red genres (I don't recommend it).
But the best thing is to keep updating chapters while continuously improving your content and packaging, especially the cover and synopsis.
By the way, I'm also four months into writing a novel on SH. My novel is set in a dark fantasy world, centered on a young mother who is a former justice executioner and now wants to live a peaceful life raising her little daughter in a world with amnesia. I'm not sure if my novel's growth is healthy or not. Currently, it has 22,000 views and 215 bookmarks. I regularly update 3 chapters per week, although updates are starting to decrease.
