If that's not enough to woo you, Craftopolis also offers a Tag Report, which shows you how people found your items by giving you the specific tags that they searched as well as the page number that they found your item on. So, if you see that your locket was on 6th page when someone searched for lockets, you know that you should either relist or renew soon so that your item will appear higher in the search listings.
To make it easy, Craftopolis has Edit Express, which is a fantastic and easy way to adjust your store's prices, item titles, descriptions, and/or quantity. You can edit every item in your store at once or check only certain items. You can completely change the description or modify by adding an extra line of text. You can change the prices on sale items by a set dollar amount or a percentage. The functionality is amazing. I can't vouch for how well this function works just yet, but I will be trying it out soon & will be sure to report back.
