To pay for Advertising on ETSY or not too?

So recently I've been pondering the idea of potentially advertising my ETSY site on secondary web pages to increase traffic to my shop. This is really hard considering I have never done the likes of this before, and I have to wonder what percentage of ETSY shop owners actually participate in this type of marketing. This is just another hurled in my dream of creating a viable, self sustaining, shop.

If anyone has any great ideas on marketing, secondary web sites, etc. please comment below.
