A good ad only needs to be four things-
Firstly and most important, be honest, if the item you are selling isn't described honestly you are asking for a bad experience. If part of your item you are listing doesn't work, let the bidder know, far better than trying to clean up the mess later. Never assume they will know "what you mean". Communication initially will minimise endless and repetitive questions, when selling multiple different items you can receive hundreds of emails in one week that could have been avoided by listing an item carefully. Keep the value of an ebay sale by respecting bidders and a better experience is assured.
- Easy to read
Some folks like to see pictures, some like a detailed description, many will just "flick" through ads. Try to make your ad cover all of these buyers. Use a small picture in the description, photos on the right or left of the ad make for easier reading, this caters for people that don't want to read the text but may do if the content is good. Use bold and larger fonts if your text is minimal but don't get excessive, use the "Review" window to make sure its not to much. The small cost for extra photos is an excellent investment. Rule of thumb, try and think of every question you could possibly get, answer all of them by presenting your ad with all that information.
This is so simple.... PHOTOS!!!! I wont bid on anything without a photo. Photos provide not only a visual media but provide honesty and trust. If you think two photos are good enough.... put in four. Take some time to select good images, I usually take two photos of everything and select the best. Plan ahead and take photos during the sunlight hours, digital cameras are great but dark images still dont do justice to an item. Ebay works well for me as it's an outlet that gives you an excellent opportunity to provide photos of items that print media can't. Digital cameras are dirt cheap and are a mandatory investment should you choose to deal on ebay. Go and find an ad with no photos and consider how confident you would be bidding on that item.
- Finish the Sale
This is where your feedback comes from, if your ads good, your items advertised honestly and packaged well, you can still ruin the sale by not communicating. At the end of a sale send an email via ebay saying "well done.. please contact me via.... how would you like the item sent...." Most people will expect you to initiate the final delivery/postage/payment. There's no need to pressure people, you just need to be pro-active, don't wait for it happen. Keep working until you have feedback or your told that your customer is happy. Answer every single email, I have had many that seem like a waste of time but have ended up in a sale.
Go ahead and sell, go global, it's amazing what the dust covered things in your shed will sell for in LA or England or.... well just about anywhere. Hope your experience is as good as mine has been and hope that some of this is some value to you.
