It's surprisingly simple to get started posting your very first auction on eBay. Here's what you need to do.

Step 1: Open an eBay seller's account.

If you've bought things on eBay, then you already have an account - just log in with it and click 'Sell' in the toolbar at the top of the page, then click 'Create a seller's account'. If you've never used eBay before, then you'll need to open an account first using the 'register' link underneath the toolbar, and then click 'Sell' and 'Create a seller's account'. The eBay site will then guide you through the process. For security, this may involve giving card details and bank information.

Step 2: Decide what to sell.

For your first little experiment with eBay, it doesn't really matter what you sell. Take a look around the room you're in - I'm sure there's something in there that you're not all that attached to and could put in the post. Small books and CDs are ideal first items.

Step 3: Submit your item.

Click 'Sell', and you're on your way to listing your item.

The first thing you need to do is choose a category - it's best to just type in what the item is and let eBay choose for you. Next, write a title and description. Include key words you think people will search for in the title box, and all the information you have about the item in the description box.

Now set a starting price. $0.01 is the best starting price, as it draws people in to bid who otherwise wouldn't, and items will almost never finish at such a low price. The next thing to set is the duration of the auction: 3, 5, 7 or 10 days. This is up to you: longer sales will usually get more bids, but will also seem to drag on forever. If you've taken a picture, add it now - items with pictures always sell for more. Finally, tick the payment methods you will accept (just PayPal is best for now), and where you will post to (limit yourself to your own country to begin with). Submit and you're done!

Step 4: Wait for it to sell.

This is just a matter of sitting back and letting eBay do its thing - buyers will find your item and leave bids on it. Some bidders might email you with questions about the item, and you should do your best to answer these questions as quickly as you can.

Remember that if your item doesn't sell then you can list it again for free.

Step 5: Collect payment and post it.

eBay will sent your buyer emails guiding them through the process of sending you payment for the item. Make sure you have the money before you send anything.

Once you've got the payment, all you need to do is pack the item for posting (make sure to use some bubble wrap), take the buyer's address from the confirmation email eBay sent you, and write it on the parcel. Put some stamps on, post it, and you're done!

I hope you enjoyed selling your first item. Now that you're starting to get into it, the next email will give you a checklist of things you need to do to be a successful seller.

Your eBay reputation is everything you are on eBay - without it, you're nothing. Your reputation is worth as much as every sale you will ever make.

If you've ever bought anything on eBay (and the chances are you have), then think about your own behaviour. Buying from a seller with a low feedback rating makes you feel a little nervous and insecure, while buying from a PowerSeller with their reputation in the thousands doesn't require any thought or fear - it feels just like buying from a shop.

A Bad Reputation Will Lose You Sales.

In fact, a bad reputation will lose you almost all your sales. If someone leaves you negative feedback, you will feel the pain straight away, as that rating will go right at the top of your user page for everyone to see. Who's going to want to do business with you when they've just read that you "took a month to deliver the item", or that you had "bad communication and sent a damaged item"? The answer is no-one.

Your next few items will need to be very cheap things, just to push that negative down the page. You might have to spend days or even weeks selling cheap stuff to get enough positive feedback to make anyone deal with you again.

It's even worse if you consistently let buyers leave negative feedback - once you get below 90% positive ratings, you might as well be invisible.

You Can't Just Open a New Account.

Besides eBay's rules about only having one account, there are far more downsides than that to getting a new account. You literally have to start all over again from scratch.

You won't be able to use all the different eBay features. Your existing customers won't be able to find you any more. Your auctions will finish at a lower price because of your low feedback rating. Opening a new account is like moving to a new town to get away from a few people who are spreading rumours about you: it's throwing out the baby with the bathwater.

A Good Reputation Will Get You Sales.

When a PowerSeller tells me something, I tend to believe them. They can be selling a pretty unlikely item, but if they guarantee it is what they say it is, then I trust them - they're not going to risk their reputation, after all. This is the power of a reputation: people know you want to keep it, and they know you'll go to almost any lengths to do so.

This is true even to the point that I would sooner buy something for $20 from a seller I know I can trust than for $15 from someone with average feedback. It's worth the extra money to feel like the seller knows what they're doing, has all their systems in place and will get me the item quickly and efficiently.

You really will find selling on eBay so much easier, and there's only way to get a good reputation: make sure you please your customers every time. But some customers can be, well, just a little difficult to please. In the next email, we ask: is the eBay customer always right?

Yes, you read that correctly: ten years. eBay was created in September 1995, by a man called Pierre Omidyar, who was living in San Jose. He wanted his site - then called 'AuctionWeb' - to be an online marketplace, and wrote the first code for it in one weekend. It was one of the first websites of its kind in the world. The name 'eBay' comes from the domain Omidyar used for his site. His company's name was Echo Bay, and the 'eBay AuctionWeb' was originally just one part of Echo Bay's website at ebay.com. The first thing ever sold on the site was Omidyar's broken laser pointer, which he got $14 for.

The site quickly became massively popular, as sellers came to list all sorts of odd things and buyers actually bought them. Relying on trust seemed to work remarkably well, and meant that the site could almost be left alone to run itself. The site had been designed from the start to collect a small fee on each sale, and it was this money that Omidyar used to pay for AuctionWeb's expansion. The fees quickly added up to more than his current salary, and so he decided to quit his job and work on the site full-time. It was at this point, in 1996, that he added the feedback facilities, to let buyers and sellers rate each other and make buying and selling safer.

In 1997, Omidyar changed AuctionWeb's - and his company's - name to 'eBay', which is what people had been calling the site for a long time. He began to spend a lot of money on advertising, and had the eBay logo designed. It was in this year that the one-millionth item was sold (it was a toy version of Big Bird from Sesame Street).

Then, in 1998 - the peak of the dotcom boom - eBay became big business, and the investment in Internet businesses at the time allowed it to bring in senior managers and business strategists, who took in public on the stock market. It started to encourage people to sell more than just collectibles, and quickly became a massive site where you could sell anything, large or small. Unlike other sites, though, eBay survived the end of the boom, and is still going strong today.

1999 saw eBay go worldwide, launching sites in the UK, Australia and Germany. eBay bought half.com, an Amazon-like online retailer, in the year 2000 - the same year it introduced Buy it Now - and bought PayPal, an online payment service, in 2002.

Pierre Omidyar has now earned an estimated $3 billion from eBay, and still serves as Chairman of the Board. Oddly enough, he keeps a personal weblog at http://pierre.typepad.com. There are now literally millions of items bought and sold every day on eBay, all over the world. For every $100 spent online worldwide, it is estimated that $14 is spent on eBay - that's a lot of laser pointers.

Now that you know the history of eBay, perhaps you'd like to know how it could work for you? Our next email will give you an idea of the possibilities.
