To find eBay, simply use your favorite search engine and type in eBay. eBay tailors its site to countries all over the world, so make sure that you are looking at your country's eBay site. For people in the United States, it is www.ebay.com. Check out eBay's seller information pages. These pages thoroughly discuss eBay's selling policies. Experiment with eBay's search features, and browse a few listings. Knowing how eBay's search function works will help you make better listings. Try changing the search results by changing the options in the "Sort" menu. Keep a good eye on listings that appear at the top of the search results and those that appear to be receiving many bids. eBay can provide you with a name, but if you come up with an attractive name, it can increase the chances of selling. Avoid anything that is offensive or lowers the value of items you are selling. Per eBay's username policy: eBay usernames must have at least two characters and cannot contain symbols such as the at sign, ampersand (&), apostrophe, parentheses or less/greater-than signs, nor can they contain spaces or successive underscores. eBay usernames also cannot begin with a hyphen, period or underscore. eBay does not allow the names of websites or email addresses as user IDs, nor does it allow anything with the word "eBay" or the letter "e" followed by several numbers. This avoids abuse by users who want to pose as eBay employees, or redirect customers to other, less reputable sites via eBay. Don't use a trademarked name (such as a brand) unless you are the owner of it. Names like "iselljunk" or "chickmagnet69" seem unprofessional and can repel buyers. Names that are hateful or obscene can be blocked by eBay. Since so many people are already on eBay, spend some time checking that the name you want is actually available and come up with alternatives when your preferred name is already in use. You can change your User ID later; however, you can only do this once every 30 days, and if frequently done, your repeat customers may be lost. Go to eBay's main page and look for the "sign in" link near the top of the page. Enter your name and a valid email address and choose a password (must have 6-64 characters and contain at least one letter and one symbol). You will be asked to choose a username after you do this. eBay will send an email to the address you provided. Follow the instructions in the email to confirm your account. If you have an existing business, you can also sign up for a business account. On the sign up page, click the link at the top of the registration page that says "Start a Business Account." You will be prompted to enter your business name and some additional contact information. Accepted payment methods vary by country. In the United States, sellers are required to accept PayPal or to have a merchant credit card account. Set up your PayPal account following the links from the eBay website, or visit www.PayPal.com. Check eBay's accepted payments policies to find out what is allowed . One important way that ebay maintains itself as a safe marketplace is by encouraging buyers and sellers to leave feedback about each other. Buyers look at sellers' feedback ratings, and buying a few items is the quickest way to add positive ratings to your profile. Try buying small items that you want or need anyway, and pay immediately to get good feedback as a buyer. Don't worry about buying things you can resell. The main thing is to establish yourself as a reliable member of the ebay community. Potential buyers who see a new seller without feedback can be very wary that you're a "fly-by-night" seller, and they may hesitate to buy from you. It's not necessary to have a very elaborate profile if you are just selling small items, but adding a picture and some information can help reassure buyers that you are a legitimate seller. For selling more expensive items, adding more information about yourself is more important, especially if you are a new seller. People do read these to try to find out more about you, so it's a good place to explain your credentials, such as being a collector, a retailer, a person with knowledge of particular items, etc.
Explore the site a bit. Decide on a good account name. Create an eBay account. Set up your payment method. Build your reputation by buying a few small items. Set up your profile page.
