So I have this epic wordpress install on one of my servers. The address for the main wordpress site is "www.oursite.com". On this site we sell solutions to other clients. These solutions include access to our content that's on "yoursite.oursite.com" but we brand the content based on the subdomain. We simply import a css file based on subdomain to style the buttons, text, etc. to their needs. This wordpress site only has one database. So you could see the same content and URL structure for either site. We installed Yoast SEO as well.
1. Is this duplicate content for both sites even though it's a subdomain?
2. If we were to block "yoursite.oursite.com" in our Google/Bing webmaster account would it hurt anything?
3. Do we need to put a rel=canonical on "www.oursite.com" regardless of what we do with "yoursite.oursite.com"?
Thanks for any feedback!
