How to improve my store advertisements (I'm only 15)?

[livelyfog404]

So I am 15, and hoping to get into college. I opened an online store to help pay for the fund, but I havent been getting many views. Every time I ask this question it gets deleted, but I just want some advice. I opened this store a few days ago, and went around to telephone poles posting advertisements for my store. I have a Google Analytics account and I only get about 4 views a day. Is there something people don't like about my advertisements? Please give me some advice on it and how to improve them?

It says redesigned because when I typed opened above, I meant re opened. I had the store for about two years, but redesigned it recently.
