Hello,
My account gives me the option (in "settings") to add company information, if renting via Airbnb is commercial activity.
It's even an obligation , coming from rules dictated by EU. (Yes, i know about the "Brexit"...)
It points me also to this via a "read more" button:

Having been recognized as some kind of company, airbnb gives you also a special "homepage-facility", where all listings appear together, also a nice opportunity to "link to it" from external sources like websites, email etc...
I have such a homepage, at some point Airbnb decided to provide it to me and considered me probably as a "commercial" host.
I am not that far, but slowly moving to something more proffesional approach
Hope this helps,
Emiel
