There are 3 main components that you absolutely MUST have in order to make money online:

1: A targeted and responsive email list
2: Quality Content to retain subscribers
3: The ability to promote offers to that list

Whilst step 3 comes down to the marketer, I can still walk you through steps 1 and 2. Building a list doesn't have to be time consuming or difficult, even if you are new to online business. In fact, all you really need to do is create a squeeze page, set up an opt-in box and offer quality material that people will gladly trade their name and email address for.
