Correct approach to a business website with separate content for personal and business customers

[CucumberGroup]

I'm laying the groundwork for a fairly involved website. The website is for a telco that caters to both residential and B2B. I was browsing the websites of the likes of Verizon, AT&T, Sprint & T-Mobile. What I saw is that they compartmentalize almost everything - all their business pages are in a business subdoman, all their investor info is in an investor subdomain and so-on.

So I'm going implement this strategy on this website update. I just want to make sure that my idea makes sense and isn't a complete cluster****.

I've attached a link to the mind map. Everything with "(sub)" attached to it is a subdomain. Everything else is a page at the root level of the top domain. Most of the visitors we get to the website are residential, so instead of loading a portal at first and asking if they're there for person or business reasons, I'm considering forwarding all visitors to the top-level domain to the personal.example.com site. Is this okay or would it be better to just keep the content in the top-level rather than forwarding all traffic to a subdomain?

Thank you!

Depending on the size of the company, it might be better to leave subdomains out of it. Subdomains are like brand new sites, so you'd be working a lot harder to get things ranking if you went that route. You don't have a ton of pages per category, so everything might be more manageable under the single domain with good URL structure.

Websites that aren't AT&T need all the help they can get, and keeping things in subfolders instead of subdomains will help keep all your authority under a single domain.

So, site.com/business, site.com/personal, etc.
