Informational Articles - How to fit into site structure?

I realized all the articles on my money site are basically buyers guides.

I want to start adding informational articles to make the mix of content more natural.

I have various silos for my different money articles, with a large topic article (for example, "All About Exercise Bikes") that lead to more granular articles ("Best Stationary Bikes", "Best Elliptical" etc...)

Should I add information-dedicated articles within the silos? Or should I dump them all on a Blog section of the website and link over to my silos and money articles?

Thread moved.

Hey David, this post is about site structure for SEO, not copywriting. Can we move this back to White Hat SEO?
