To be honest with you, there is no easy way to make money online. Anyone that says this process is easy is going to try and sell you something that probably does not work. Making money online involves the following:
*Find a problem that you are passionate about - As a teen, you are probably passionate about clothing. So lets say the problem is people are looking for a good place to shop for clothing. Now you have your product.
*Create a website, maybe using a template at wix.com or angelfire.com giving free information about your solution. Write some articles and take a few nice pictures.
*Time to monetize - Have your parents set up a Google Adsense account. Follow the steps to place the banners on your site. Now you will get paid for people clicking on advertisements. Next, try to search for apparel affiliate networks to sell their products.
*Time for traffic - Building traffic is the hardest part when it comes to making money online because it takes continuous work. However, it is very rewarding. I provide free marketing training at Wealth Creations Network. It is all free but you will need to have your parents sign up because you have to be 18 years old!
