I have not done anything on etsy so this is all just armchair crap from me-- but I've read that they are doing very poorly since they opened trading to vendors with non-handmade items. They've been flooded with cheap mass produced items at prices that artisans can't compete with, and buyer traffic to the website has also slowed, since etsy customers are not generally interested in the mass produced stuff that's all over their platform now.

So I don't know if you can rely on incidental internet-browsing traffic- it seems like those days are over- but you might have some success if you do your own advertising legwork and treat it more as a platform for displaying all your work and completing financial transactions securely.
