taaj, you need to write more. you can't just write 4500 words (17 amazon pages = 4500-5000 words) and expect popularity ..

well, i don't know what you're aiming for, but 4500 words won't get you much of anything

short story collections generally do poorly

you have to write a novel 60000- 80000 words and there's all sorts of factors that are important to how well that novel sells
cover art, blurb description, first five pages, the story itself, the title!

i can give you a ton of ebooks and reading material if you want to succeed in self pub or a fiction=writing career

writing 5000 words (and it's not even one story, it's multiple stories) and then marketing it to death is not going to get you anywhere
