One helpful site for Etsy sellers is Craftcult Type in your shop name and it will show you who hearts your shop, which items have hearts and how many, and who hearted each item. It also has tabs that show you if any of your items is being featured. I've been checking this site every day. I get excited when I have new hearts
Another helpful site is craftopolis. Type in the name of your shop and it will tell you if any of your items are in any of the current tresuries.
