NNNNOOO!! Not the promo games! Yes, they will get you views and faves, but they are not QUALITY views and faves. It is highly likely that they people playing those games, who are other etsy sellers, are not your target market. I spent way too much playing those games, and got nothing in return. It was only after I stopped it with them, and worked on adding more products, worked on my SEO, and marketing off of Etsy is when my sales went up.
Like Anna said, find a fashion blogger, who has a large and credible fan base, and ask them to feature your products.
Hit up your social media daily. That way your followers won't forget about you.
Have you tried selling at craft fairs?
