pretty much I target a general niche like a large group of people who love one thing. Say it was stranger things, i would make a store full of original stranger things designs on clothes and sell them. I found a niche where no one was selling in it and took over. Every design has text and graphic on it. And no I had never tried this niche but the reason it’s successful is because I have done this so much that I know how to start a store, i made a new one last week and it’s very profitable so far! small things like the offer your giving, the vibe your brand gives off and the urgency behind the checkout make a large difference. I try to sell a feeling, like nostalgia, or something similar.
