SEO noob questions [CPA Project]

[PUT0M0N0]

Hello, I'm working on my first SEO project, and I have a lot of doubts. I will try to explain them as best I can.

For all the examples I will use a download pokemon niche, because it is similar to mine. I'm targeting to long tails with low competition like:

download pokemon sun and moon
download pokemon blue
download pokemon red (remember this is just an example)

Okay, my first doubt is... In all my post I'm setting up a locker to lock the download and maybe it affects to SEO. Is it better to redirect to a download page through a no follow link and set up the locker there? The download page should be in the same domain or an external one?

Second doubt is that I'm posting a table with the characteristics and another one with the installation steps, and I post in all of my posts. These tables are pretty similar... Will Google treat it as duplicate content or as it is in the same domain does not matter?

Whether download page on same domain or external domain, the only thing matter is your main money page. You can link to external page with nofollow link if you want. If you have doubt about locked links on SEO, then remove them and put them back when your site start ranking in TOP 10.

I do not understand what you mean with "the only thing matter is your main money page". So let's continue with the previous example. My domain is http://downloadpokemon.com and I have several posts triying to rank for long tail keywords, I want to rank these posts not my home page.

http://downloadpokemon.com/blue/
http://downloadpokemon.com/red/
http://downloadpokemon.com/sun-and-moon/

Currently the locker is in these posts, and I thought about moving it because maybe it can affect to SEO. If a make a page called download and redirect every single post (throught a button with no follow and target blank) to the download page where is the locker. It will be fine or I need to create a different download page for every post?

http://downloadpokemon.com/download/ or http://anotherdomain.com

I will do this "make a page called download and redirect every single post (throught a button with no follow and target blank) to the download page where is the locker"
