For someone who is completely new to marketing, you would be well advised to start reading about different ways of marketing. You can build websites, write articles, and the list goes on.
It doesn't matter what kind of background you have in marketing, it would be best to pretend you know "nothing" about internet marketing. Many people think they know it all and wind up failing.
Don't sweat the little details of everyday learning. The best way to go about your business is to simply "dive in". Be persistent and never give up. Many of today's well known marketers got to where they are, because they never gave up.
You would be surprised how many marketers actually enjoy helping each other out. This business isn't about trying to outdue the other guy, it is about helping and giving back. Ask questions and learn as much as you can.
One of my favorite methods for teaching newcomers, is the method of SEO. This stands for search engine optimization and is the process of being able to get your website to rank well for a particular search term.
If someone buys from you once, they are more than likely to buy again, provided they want the item. By having a form on your website to capture visitor information, you give yourself the chance to sell to your visitors many times over.
There is also the option of selling on eBay. Many people from all walks of life use that auction site to sell goods on the side. You can too if you really want. Visit www.sky-high-auctions.com for more information on getting started with eBay.
