Let me give an example just to make sure I'm understanding this one correctly.

If I have a Cat themed silver site and a Dog themed gold site, I create this RSS feed using any PLR content I want using my best Dog themed keywords, link back to my Dog site and run it from my Cat site.

Now I imagine i could also use Dog themed PLR content as well. The goal is as many one way links back to my Dog site from this feed (which can be replicated and run on any number of "tin/silver" sites) as possible regardless of the feeds dog content relevancy.
