Ecommerce Marketing – Shopify Neighborhood

I am questioning as to where the best locations to promote at. I have actually got a Shopify store and I’ve been trying to find out how to get sales from my shop, but I can not determine where to promote at. I have actually heard that Facebook and Instagram are expected to be good places to market at, but I’m not convinced that those are the only or the finest places to promote at. I’m looking for concepts and suggestions.
