Sub domain on root domain
- by dror
I have a site, actually a "portal"/ "directory" for service providers.
Now, for start, we opened every service provider own page on our site, but now we get a lot of applications from those providers that thy want sites from their own.
We want to make every service provider his own site, but on sub domain url. ( they don’t mind… its ok for them)
So, my site is www.exaple.com
There site will be: provider.exaple.com
Now I have two questions:
can it harm my site in SEO?
if one from those sub domain , punished by Google because is owner do "black hat seo" , how it will affect the rood domain? It can make the root domain to get punished?
