Everyone loves free, and one of the best ways to get people to buy your products is to offer them a teaser for free. And Web 2.0 offers many ways you can get your product samples out there, give a people a taste of your product and show them where they can buy the full version.

Obviously, this method isn't for everyone and is suited only to certain products. If, for example, you sell cars it wouldn't make much sense to offer people a free wheel as a teaser. However, if you sell online tutorials, eBooks, audio books, video content or software, this method works really well.

You will also benefit from backlinks to your website which will help your standing with the search engines.

So, here are some tips on how to give potential customers a taste of what you offer and leave them wanting more.
