I have multiple servers which host several sites, some of them being QA environments.
Unfortunately, Google has found its way to some of them, and it is displaying results which are in fact competing with the corresponding live site URLs, for multiple sites.
Is there a way I can tell google, via analytics or something similar, to simply delist all of the existing information for subdomains *.a.example.tld
or *.b.example.tld
?
