I have some experience and it can definitely be done but it is not as easy these gurus claim. Many of them have only made money teaching other people how to make money online. Lately it's become even harder because Google, MSN and now Facebook are unlikely to approve your ads if you are a first timer selling a pure information product--mostly because information marketers took their craft to a whole new level and got into the habit of repackaging freely available content (or books whose copyright had expired) and reselling it. Between 2003 and 2009 some people minted millions doing this in what was then known as "Get Cash From Google Program"!

thanks for the info

I created and sold an info product by doing webinars to a niche audience. It can definitely be done.

How much did you make if you don't mind me asking and how did you build your audience?

I sold each copy for $199 and I did it by doing webinars for the target audience. I contacted people that ran webinars (they often want guest speakers) I would do a presentation and then sell copies after.

A lot of people wanted me to do other consulting work for them as well.
