Silo - Online-Shops?

Hi guys,

I'm starting my SEO learning journey with a website that I created like three months ago. It's not an affiliate website, but rather something like an edu website, where I share my 'knowledge' on a topic (with Books, Online-Courses, Videos).
I came across the topic of SILOS and website structure. I'm wondering what would be better for the user (user experience) as well as SEO:

Is it better to create a structure like domain.com/video-course and have like some information about the videos and what you can learn and sell that directly on that site (like a section with "add to cart" on the bottom of the page). Or would it be better to create an extra domain.com/shop where are all products and domain.com/video-course point to the shop?

I'm thinking about the right cluster of keywords. Like when you have domain.com/shop you could add keywords such as 'buy video course' (which is commercial) and keywords like "what is this video course", "video course", and so on (informational keywords) to domain.com/video-course

Love hearing your opinions!

if you have multiple products and want to offer a centralized shopping experience, creating an extra domain.com/shop can be a good idea. You can still link domain.com/video-course to the shop page where users can explore and make purchases.

Thanks for your post! You sound a little bit like it wouldn't be necessary? I'm just thinking about the keywords and their intention. Everything that I'm reading says to sperate those. Commercial on one site and informational on another (or something like blog posts that are linking to the shop or "main" site).

Have I understood that correctly?
