site structure and hard silos - how to choose correctly

Hi,

I'm currently thinking about the site structure of my 1st website. Total newbie here so I apologize if some things I say don't make sense :)

The site will be a mix of affiliate links (mostly courses) and courses I'll sell myself.

I'll be using pages and hard silos.

Since hard silos can't be changed without trouble once they are set, I'm trying to think about how to differentiate the 2 kind of courses.

For example, perhaps something like this:

- for affiliate course: homepage/recommandations/courses

- my personal courses: homepage/courses

In the "Recommendations", I'll have affiliate links to Online courses, apps, some amazon stuffs. Maybe also some non affiliate links like Suggested Youtube channels.

What to do think? Have you ever encounter a similar issue? Is it bad to have "courses" in two different URLs even if they are not in the same place? Should I change "Recommendations" by something else?

Thank you for your help! :)
