Need Google Analytics help

I have two websites to sell my fidget mats and will probably have more in the future. So far, I haven't gotten any sales on either Etsy, my personal website, or Inspire Uplift. How can you help? Here are my links: https://www.etsy.com/shop/ReneeHeiss
https://www.reneeheissart.com/fidget-mats.html
https://www.inspireuplift.com/shop/QuietlyCreative

What am I doing wrong?
