Here are the things you have to do, in order to post the initial eBay auction of yours:

1) Open a seller’s account on eBay.
If you are a buyer on eBay, you should already own your account, so simply log into your account and click on ‘Sell’ at the very top toolbar of the web page. After that, you should create your account as a seller.
If you have never been on eBay yet, a new account will need to be opened, first and foremost. This can be done by clicking on ‘register’ under the toolbar. Then, click on ‘Sell’ and then create your account as a seller. eBay will then come up with a guide that can speed along the process quite easily. To keep security, you may have to give out your bank information and credit card details for future transactions.

2) Know what you wish to sell.
If you are just starting out and experimenting on eBay, this does not matter much. Just look around you and if there’s something you no longer need in there, try posting it. This could be anything from tiny books to CDs.

3) Submit the item.
Once you click on ‘Sell’, you can start listing the items.
A category will need to be chosen. The best way to find one is to simply type what you perceive the item to be and then eBay will select it for you. Then, write a simple title along with a description. Add keywords that people would want to use in searching for it, as well as other information it may need in the box of descriptions.
Then, you will need to set a certain starting price, of which $0.01 would usually be the best since people will then be very interested in bidding for the product. Then, you will need to set a certain bidding duration, which is completely your call. The sales that last longer usually get the most bids, but they also take forever to end. It is also important to add a picture for the item, as they tend to sell more.
Lastly, choose the payment method you want to use; PayPal would be best, and where the post should send it.
Then, click on ‘Submit’ and that’s it!

4) Wait.
All you have to do now is sit back and wait. Buyers will eventually see the item you are selling and bid on it. Several buyers may ask questions and these should be answered as fast as possible. If you don’t sell the item, you can re-list it if you wish.

5) Get paid and send it.
The buyer will be sent an e-mail, wherein he will be guiding in the buying process. Ensure that the money is there that was agreed upon before sending it. Once the payment has been received, all that is left for you is to pack these items and posting them.
