It has been mentioned on here, Try listing your item's for over 11 days gives the bots on search engines time to find your items,
So when anybody is looking say on google hopefully google bots will have seen your item and show it in the list, Will show as eBid then some of the advert of what you are selling,
Try it type in item in google search and see pending how many are there been sold you will see a few ebaa with adds of what you are looking for as well as the other places.
Worth a try Ken
