One of the easiest, most profitable ways to make money is by writing and selling digital products on eBay. Browse through the current listings and you’ll see that eBooks sell from as little as a penny to $17 or more. Clearly, this is a product type worthy of your consideration but I bet you’re wondering where all those sellers get their material.

The truth is, a lot of them write their own. Even if you’ve never thought about being an author before, now’s the time to think about it seriously. And, rest assured, creating an eBook isn’t nearly as difficult or scary as it might sound.

In fact, New York Times best selling author Robert G. Allen says each of us has at least one book inside us. The good news is that most of us actually have several potential eBooks we could write!

Writing a successful eBook is all about sharing what you know and the key to having a hot seller on eBay is all in your subject matter. The narrower the niche your dealing with, the better you will do. This is merely a matter of filling a need while minimizing your competition.

For example, right now there are literally hundreds of "make money fast" or "loose 95 pounds in 10 days" eBooks selling for under a dollar on eBay. Clearly, those two topics are overexposed and you’re sure to find others worth eliminating for the same reason.

What’s left to write about? There are a myriad of topics left to choose from. "How to Make Great Money with Bagpipes, an eBook on CD, has been selling for $17. So, if you have a career, hobby or particular interest with years of experience behind you, write about that. If not, identify a specific, narrow subject that you have learned a lot about and create a digital product to sell on eBay.

Pick information-heavy subjects that will quickly appeal to the right people. Titles like "101 Golf Techniques" or "How to Keep Your 1965 VW Running Smoothly" will immediately attract specific committed buyers willing to pay for the information. A tax accountant specializing in home based businesses will do very well with "10 Ways for New Home Based Business to Organize Their Taxes" as would someone who has spent years perfecting organic gardening techniques that work within a city location.

If you are now intrigued by the idea of creating an eBook but feel that you don't know how to write — no problem! The best eBooks are written in a conversational manner. Remember the last time you explained to a friend how you grew this new type of organic squash? Take those words and write them down!

Remember that people are looking for eBooks which are easy to read, easy to understand and contain strategies that are easily implemented. They also like information with helpful links and visuals so take your own photos or pull some from a website that includes public domain art. Make sure you have a nice cover page (even if it means shelling out some money for an art director) and consider a distinct picture for your listing that short hands what your book is about.

For those of who would like to offer a higher-priced option, eBooks sold in CD format (which requires minimal shipping costs) sell very well too.

The best part about this idea is that you can give it a try with little or no money invested, just a short amount of your time!
