People are naturally terrified when you ask them to sell anything and when it comes to trying to earn money online, the same fear is very much evident. Alas, the good news is that there are thousands of folks making money and some even earn a pretty comfortable living online without having to sell anything.
I am well aware that this is one of those statements that usually causes people to doubt the person uttering it or writing it down in this way. So I will quickly give you an example of just one program where folks are able to earn some serious money online easily and without having to sell anything.
Have you heard of the Google AdSense program$%:
Numerous webmasters and bloggers earn their money online from the program which pays for clicks that happen at your site. Nobody needs to buy or make a purchase for you to make money. You see the smart folks who are really into math worked out the fact that a site needs dozens of visits and sometimes hundreds of hits before they register one sale. So rather than paying the commission to the one site that refers the person who actually makes a purchase, the commission is divided amongst every hit that makes it to the site. This gives everybody a huge incentive to keep on sending hits by displaying the AdSense ads at their site.
Little wonder that the AdSense program is by far the most popular on the World Wide Web and most people who earn money online make their cash from this program.
There are of course numerous other ways one can use to without having to sell anything online.
