Always Include a Photograph,

Lack of adequate information is almost certain to bring lower winning
bids and in many cases no bids at all.
3. Always Include a Photograph. Pictures sell. Good pictures sell
even better. There are a very small percentage of items that don’t need
a photograph. The rest do. Provide multiple photographs for expensive
items (e.g., at least five or six sharp photographs for a vehicle).
Sellers Beware
I know of a woman in Sonoma County, California, who has an
interesting eBay strategy. She buys items on eBay from auction listings
that include poor photographs. She then takes good photographs
of the items, relists them on eBay, and sells them for a profit.
Great moneymaker.
4. State Your Requirements. Clearly state your requirements for sales
to inform bidders of what to expect. Be sure to include everything that
will cost winning bidders money.
Tell Them Before
If you intend not to sell to bidders with undesirable feedback, state
that in your sales requirements. Then check the feedback on the
leading bidders. If one is undesirable, email him or her before the
auction ends to state that you will not accept the bid and ask him
or her to retract it.
5. Remember the Search. Craft your auction title to include keywords
for buyer searches and to be readable.
6. Answer Inquiries Immediately. Always answer bidder email
inquiries immediately. If you wait, you may lose a bidder. A robust
auction ad will help reduce bidder inquiries.
