Online selling is subtly different from traditional selling because the buyer does not actually see the item until after it has been paid for and delivered.
Tips about item descriptions and photographs can be read in our article How To List An Item
It is always a good idea to put ones self in the buyers position and ask the question what do I need to know about this item before I purchase it. If you get a number of e-mails asking for additional information, then either the Title, Description or Photographs are lacking information.
Would you buy an expensive Rolex or Cartier watch from a one-line description and an out of focus photograph?
At any antique fair, the first thing people do is pick up the item, to look at it, feel it, examine it or ask questions about it. When selling online, only your Title, Description and Photographs create the virtual conditions of the antique fair.
What is required to sell a stamp, vintage clothing or an oil painting will vary according to the item and its value. A low value item represents a small risk if it is not as expected upon arrival, but an expensive oil painting, stamp or piece of silver represents a large risk if it is not what you expected.
The Title, Description and Photographs should send a clear message to the buyer that since you have taken the time and effort to describe and show the item including dings, dents and flaws then you are trustworthy since you are not trying to hide anything. Whilst this may not end in a sale, but it takes away a major reason for people not to buy.
Regarding the number of photographs. Most broadband accounts include 4 to 10 MB space for a small home website. Some auction sites restrict the number of photographs you can list per item, but you can host your own photographs and place a link in your auction advert to these photographs, so you are not restricted to a certain number of photographs after all.
