Testing server indexed in Google
Assume our internet site domain name to be www.example.com.
And also we have actually developed a different screening setting within our major domain name: Claim: www.project.example.com.
So we have 2 variations within our major domain name web server. One is for screening and also constructing new updates and also the various other one is real-time web server.
I see www.projects.example.com indexed in Google which is our screening web server.
Exists any kind of alternative to limit this screening setting from being indexed in Google?
