Aside from that, I really don't know how people get reads at all. Would like to know if you've got any advice on this as well. I've been writing and uploading my stuff online for over six years but barely anyone has shown genuine interest in my works. Maybe I'm just not good at writing. I don't know.

Some ways to get traction: If you're in Social Media (like FB-Groups), there are some that allow promotion (often with conditions, like in the thread that is posted once a month). This brings readers interested into your genre on board.
Post often at the beginning. This way people become more interested.
Have good cover. It's the first impression of your story. Have a cover that tells a story in itself.
Have an interesting blurb/synposis. After the cover, it's the second thing potential readers will consider whether your story is worth the while or not.
While this forum doesn't allow self-promotion, you can use the recommendation section to suggest your work to readers that are looking for something like your fiction (just make sure not to necro threads).
If you engage in the forum life, people are more likely to check your story, especially if the start thinking, that you're a cool person. Having a signature that links to your story is also good.
It also helps to write stories people want to read. There are also writers who write what they want and post it, because they see no reason not to let people read it, but if you're doing your own thing, it may become harder to get fans. Main-stream is a thing, after all.
Be beware though, that the more people read your story, the more you'll find that won't like it.
