First thing is to learn the lingo.
There is really a learning curve involving jargon. A beginning is to read around a bit and pick up a basic view of what affiliate programs are, what an autoresponder is and what a squeeze page is.
After that you need to know a bit about the different business models.
You can function as a writer who primarily sells their own products. Or as an affiliate who reviews and sells other people's products.
Do you want to sell real goods - like furniture or would you prefer to sell information products?
Or perhaps function mainly as a blogger?
There's no right or wrong here - but there is something which suits you and which you do most easily and make a success of.
Make the most of this and other communities - after all we may be your first customers!
All The Best
