Module 2: Website Structure

I am trying to decide the best way to build a presell website and can’t seem to find an answer yet.

When using the free SASPremium Hosting, it appears that we are just creating landing/ presell pages.

If I create a website via bluehost and wordpress I have the option to create a website with a home page/about us/etc and than use subdomains (such as as my presell pages.

To me, it seems that to make a website look more professional if I had a main home page that is not a presell page and than the presell pages as subdomains. So is it more advantages to do that? Or is it better to simply create presell pages and not worry about having a main home page?

Thanks for the guidance!
