Your plan is a bit vague and reads like you copy-pasted it from somewhere. What kind of CMS did you use for the websites?

I assume you are targeting low competition keywords. How many articles/content are you going to write per Amazon niche website and how many keywords are you going to target? Are you going to list many products? What is the structure of the content? What are your competitors doing?

These are all the questions you should be addressing before you start. Once the structure of the website and the content is perfect, you can start thinking about backlinking.
