There are tons of opportunities to make money online, but what are the BEST opportunities to make money online?

Specifically, what are the best opportunities to make money online... when you don't have anything to sell?

It might surprise you to hear that not having a product of your own to sell needn't hold you back from taking advantage of the online marketplace.

In fact, you may actually have a lot to sell -- you just don't know it yet!

So here are the top 5 opportunities to make money online... even when you have nothing to sell:

1. Sell an eBook: An eBook is an information product that people purchase and then download online, meaning there are no shipping costs and they receive their purchase immediately.
   
   But eBooks aren't just great for consumers -- they are THE most profitable of all the opportunities to make money online for sellers, too. That's because, once you've written your eBook -- ideally on a topic you know about and know there's a demand for -- there are no more costs to eat into your profits.
   
   No print costs. No storage costs. No shipping costs.
   
   Simply put, eBooks = 100% profit!
   
   And because most Web users search for information online, there will always be a demand for well-targeted information products.
2. Promote other people's products: Another of the best opportunities to make money online is to promote other people's products, or "affiliate" products.
   
   An affiliate program allows you to promote another company's products on your website -- in return for a sales commission.
   
   You can find affiliate programs to join at websites like www.AffiliateGuide.com and www.AssociatePrograms.com.
3. Place advertising on your website: You can also make money online by signing up to be a publisher for a contextual advertising program like Google Adsense.
   
   After you become an Adsense publisher, ads related to keywords in the content of your site will show up on your Web pages. This strategy is especially suitable for high-traffic, content-rich websites and blogs.
4. Sell a service: You may not have a product to sell, but do you have a service to sell? Are you an accountant, a writer, a dance instructor... ?
   
   You can promote and sell any practically service online, and you can even create tailored services to sell as if they were products. For example, if you're a writer you could offer a résumé-writing service on your website for a set fee.
5. Sell your "junk": The last, but not least, of the top 5 best opportunities to make money online is to sell stuff you don't want anymore.
   
   Websites like www.Craigslist.com (a classified ad website) or www.eBay.com(an auction website) allow you to sell anything and everything. You might not want that bright yellow coffee table you inherited, but someone else might!

So, if you think you have nothing to sell, look around -- there are opportunities to make money online everywhere!
