I have a SaaS platform where people can create their own white labeled job boards.
My main product domain is www.myproductdomain.com
When clients sign up they automatically get clientname.myproductdomain.com
. They can also choose to use a custom domain by setting up a CNAME.
This means that every client by default has at least one domain, but could have two pointing to the same content if they choose to use a custom domain, i.e.:
clientname.myproductname.com
<-- default subdomain on sign upwww.clientname.com
<-- if they choose to setup a CNAME and have a custom domain
This essentially means there is duplicate content. In the above scenario, when Google hits the default clientname.myproductname.com domain, I do a 301 redirect to their custom domain. Does this seem problematic? Is there a better approach?
