If a subdomain becomes banned will it effect the main domain?
The answer is yes. It may get the main domain banned
if they are linked to each other. There has been proof of main domains being banned, yet i have heard of many instances where they have not.The main domain may not get banned under certain circumstances. The question shouldn’t be whether the main domain can get banned because of a subdomain, but instead, why would your subdomain get banned in the first place.If you want to experiment with untested or controversial methods, do so on a new domain.
