Here are a few things you may want to consider when selling on ebay.
1.Try to place your ads on Sunday evenings. The reason is if you list an item on sunday for 7 days then it will end the following sunday. Most people are at home on a sunday night, so they will be there to bid on ebay.
2.Next is describe your item in detail. Even though you have pictures on your ebay listing people like very detailed desciptions. Use colors, brands, sizes, material, measurements. Decribe your item like you would if there were not any pictures.
3. Good Pictures. If you don't have good visable pictures then no one will want to buy from you. Make sure your pictures are clear, upclose and use many. The more pictures the better.
4. Shipping Costs- Do not charge an outrageous shipping rate. People are more likely to bid on something that has Free Shipping or low cost shipping.
