While the WordPress MU Domain Mapping plugin is used to map WP network subdomains to other domains, all subdomains are beiing indexed by Google.
Clicking the indexed url's (subdomain.example.com) leads via 301 redirect to the mapped domain; so thats good.
- How to make sure in future installs the subdomains are not indexed by Google when this subdomain of the network is mapped to another domain?
- How to solve this issue at current network installs?
One example can be found at network install http://recruytment.com
