There are different types of Internet marketing.
One of the common types of Internet marketing is affiliate marketing. This is where marketers promote products and services from other companies. Affiliate marketing is very easy to get into. For one thing, it does not cost any money to join. However, it does take a couple of days to get approved in most cases. There are affiliate programs that approve applications at a quick rate. Often times, they are part of an affiliate network that you have already signed up for.
The only disadvantage that affiliate marketing might have is that you are only paid a percentage. Therefore, you are going to have to sell a lot of products depending on what you are promoting. That said, there are affiliate programs that pay a lot of money for sign ups or other forms of action which include a purchase. Even though you are only making a percentage of the full sale, you could still earn a lot of income from being an affiliate if you promote the right products. With other forms of Internet marketing when you sell your own products, you will be able to keep every penny you earn.
