Depending on how new you are to all of this, some of it may be too basic and can be tedious to get through. Do it anyway.

It's very easy to get distracted, lose focus, start bouncing around, and before you know it, you are completely lost.

There is a lot of information here and it can be overwhelming so just go a step at a time. That's most likely your best bet for getting a solid foundation and seeing exactly what you are in for with affiliate marketing.

Best wishes for your success.

Think I just responded to your other post but I'll sum it up quickly here. Labman listed the tools available to you below but I would follow his link to the getting started training and work your way through each of the lessons. It is pretty straight forward and will help you get on the path to starting your own online business with step by step instructions. If you are just starting I do recommend that you try to keep focused because there is so much information on the site and it can be easy to become overwhelmed or confused.

I had shiny object syndrome and kept clicking on different links until I was so confused I didn't know up from down. Once you get focused on setting up the basics it will be easier to replicate in the future and you can focus on building out your ideal site.
