I reviewed mine and looked at all the listings Etsy thought were similar. About half of the comparisons were inaccurate. It would be more useful if it would show all my listings. Perhaps they only show listings that they think are out of range.
Oh, get this big time. I have some items that I could sell a lot if the price were low enough, but I would work a lot more and make less money if I have to make a lot of the same thing I burn out on them. I made a pull toy for a custom order and offered it in my shop for a much higher price than the original. It sold, and I raised the price. Every time I sold one, I raised the price, and they kept selling. I got tired of making them and eventually disabled the listing. I follow this model with most items until I get something I can live with. A balance between sales, profit, and work. I refuse to work for free.
I don't have sales. I firmly believe that all you do when you have a sale is train customers to wait until the item goes on sale. I believe this because that is what I do.
Sales are so bad now that if I didn't have a lot of low-priced items, I would be making few sales. The interesting thing to me is these low-priced items are the ones that make the most profit percentage-wise. Material cost is near zero, and they are very easy to make.
