It can be tricky in getting started. There is soo much information to learn about all different types of internet marketing. Such as PPC advertising, CPA, Affiliate marketing, clickbank, etc. My best suggestion to you is to start with something fairly easy to understand. I like to encourage newbies to checkout YouTube as it's a web site that gets billions of views each month and can target just about any niche. Any hey, it's free marketing.
I would look in the YouTube section here and see what others are posting. I have seen a few just in the past couple weeks here show up for free.
Best of luck in the journey!
