It depends on what you are selling. Ebay usuallyis only good for the most in demand items, eg: cabs, or LV mirrored items etc.
If the start bid is too high, people won't even look at it. Sometimes you have to jsut start low and trust the market. Set a reserve if you get worried, or else you can always at least resort end the auction if you aren't getting your price.
And even though you may think its a fair price, we all tend to want to set a higher price, then the market sometimes really demands. So you may have to let it go for a little less then you hoped.
A lof of factors can be, start and stop time, generally try to set auction end dates on weekends so more people have access.
Pictures-you don't need a ton of pictures but you definately need good clear pictures.
As much information as possible, if you are the original purchaser stating that is helpful, when, where, and why you are selling give people more faith.
Another way to get people in...offer free shipping! Who doesn't love that.
