Like the home page, the category listings on the site are randomised every four hours. So sometimes you'll have to browse to see your product, and sometimes it will show near the top. At this stage we have quite a lot of products listed on the site, so if you have to browse a while then that's why. The most important way to make sure people see your things is by marketing them.
Remember to make sure that your photos are looking clear and bright so that your product stands out. For feedback on your photos, ask your peers in the Hello Pretty Sellers Community on Facebook.
