I've been on etsy since July or so. I've sold lots of stuff, but not knitted items. I sell yarn and African violets as well as my knit items. I'm not sure what the secret to selling handmade yarn items is. But, I have EVERYTHING I do connected to each other. I have a yarn website, sell on ebay (to end by the end of the year...had enough of that nonsense), bonanza (very poor performance), and a website (free) on ecrater. Two facebook pages, one for yarn, one for violets. Blogs connected to yarn, knitting, crocheting, and African violets. One also for Buddhist malas that I make. The facebook pages, I paid to advertise to get followers. You control how much you spend. The blogs, they get traffic from me promoting them on facebook pages and people who come along them from ALL OVER THE WORLD. I'm on blogspot and I can see where viewers come from. Usually from facebook, but literally from all over the world. Do they buy? I'm still trying to figure that one out. But my point is, everything is connected. There are links to etsy, facebook, bonanza, ecrater, and I post things on the blog and let people know on facebook. I also put in my ebay listings I'm leaving ebay and moving to other sites. I get inquiries from people on there where I'm moving to. I give them a list as well as one goes in every shipment. I have seen that produce sales.
I have google analytics for Bonanza. Literally hundreds of views and practically no sales. I think the format of buy it now or best offer confuses people or they don't want to "join" something else.
It's a ton of work. I have to keep coming up with interesting content for the blogs and facebook to stay in faces.
