Almost all of my online retail sales through 3rd party facilitators like Etsy and Zibbet were not with people who cruised to my ads via the virtual shopping aisles of these sites. Rather, most of my customers found me through my personal website, photo postings on other sites like Pinterest, social media postings and Google searches.
Follow the online sales "holy trinity":
1) Find your niche, so your things stand out quality and design-wise
2) Network all the time and in every way possible
3) Apply good SEO techniques in your ads, and use words/phrases carefully so search engine spiders find you, and place your ad links higher in the search results
