I am running a multisite network and am using the Domain Mapping plugin. Now we've wanted to check with Google the amount of indexed pages of the main domain using site:main domain.com.
As a result not only the pages of the main domain showed up, but also all the sub sites with their subdomains. No matter if they have a mapped domain or not.
If you click on such a search result with subdomains, the mapped domain works, but now we wonder how it can happen that the original sub domain is index and if that is causing any problems with duplicated content.
Any experiences anyone?
Many Thanks, Tee.
